      Gunsmithing - Patrick Sweeney

      Introduction

      Please allow me to introduce myself is the beginning of the Rolling Stones’ song Sympathy for the Devil. Great music, bad sentiment. This book is the second one I wrote for a publishing company known back then as DBI Books. That book first saw the light of day in 1999, which is not only in a previous century, but in a previous era and a time that was almost quaint. The internet was only a few years old, all jokes aside about Al Gore inventing it by voting for the program that created it. If anyone has any doubts about the absurdity of that claim, just consider this: arriving at the Patent Office, claiming a patent on something one merely voted for.

      But, I digress. In 1999, the date of September 11th was known only to historians of European history before the Age of Enlightenment. The Assault Weapons Ban of 1994 was halfway through its misguided life, and attention was only just beginning to be paid to the AR-15 as a rifle, a system and a way of life.

      Sniper rifles were still wood-stocked or with some new ones, synthetic stocked, bolt-action, and looked like heavy-barreled hunting rifles.

      We were five years away from the invention of Facebook. Little did we know that just in the year 2000 alone, former Major League pitcher Bob Lemon, actress Hedy Lamarr, and actor Walter Matthau, along with the science-fiction writer A.E. Van Vogt, would leave us. I have to say, had I known that in the year 2000 the group N’Sync was going to be all over the charts, I’d have asked for a do-over.

      1999 was also the year I went to the Philippines for my first IPSC World Shoot. I did three more after that, ending up with a pair of Team Gold Medals for my travels.

      A lot of shooting things changed or went away. No one talks about fire-lapping barrels any more. Barrels have become so good, and rifles are now so accurate right from the factory, that some defy improvements. Likewise with ammunition. It used to be that you could pretty easily load more-accurate ammunition, ammo tailored to your rifle, and that you bought factory for practice and to make once-fired brass. Now? Factory ammo is the standard against which you measure your ammo, and often fall short.

      Since then, the gun-control efforts of many have hit their high-water mark, and have decreased. Oh, there are some places where firearms restrictions are as bad, or worse than ever. But now, concealed carry is at least theoretically possible in almost every state. Suppressors are legal to own in at least 41 states. Firearms ownership is at an all-time high, not just in the numbers of firearms, but the numbers of owners.

      There’s a curious anomaly in firearms statistics. Actually, two. Since 1999, firearms purchases have been ever-increasing. If you took the estimates of how many firearms were owned in America, in, say, 1995, and you added to that estimate the reported number sold, you’d come up with a figure higher than the current estimates. I joke about creative accountants who can make the addition of two plus two equal five, but in this instance, the sum seems to be three.

      The current estimates of firearms ownership are 350 million, for 320 million residents in the United States. Works for me.

      The other anomaly is the increase in firearms, but the decrease in households owning firearms. Depending on the source, the percentage of homes owning firearms has dropped from the mid-50% to the low-40% ranges. Or the 60’s to the 40’s, or, well, you get the idea. According to pollsters, surveyors, and so on, the percentages are down.

      Huh? We’ve been selling/buying firearms at the millions per year, and the number of people owning is going down? The span from 1999 to 2011 shows the low at 6.3 million, and the high at 10.0 million NICS checks (The actual firearms production figures are published by the ATF, but the NICS check total covers them all, and is a good-enough rough estimate.) In total, from 1999 through 2011, there were just about 100 million NICS checks done. That’s a lot of guns.

      Now, consider this: You’re at home, the phone rings, and it is a pollster, asking questions. That you don’t hang up the moment you hear them is a minor miracle. They ask, Do you own any firearms? My surprise is that anyone answers yes, let alone some 40+% of respondents. Me, I don’t talk to pollsters except to torture them mercilessly.

      The point of all this is simple: More people than ever own firearms. More firearms than ever are in the hands of users, hunters, collectors, competitors and those seeking safety in a dangerous world. And more than ever, they need knowledge on how to keep their firearms running, improve them, and be safe.

      Some Legal Considerations

      Okay, time to let a bit of the real world intrude into our wonderful little corner of the universe. Ever hear of a governmental board called ITAR? They are the International Traffic in Arms Regulation. This is a nest of bureaucrats whose job it is to keep American industrial and firearms secrets from being dispersed to our enemies and competitors around the globe. If they actually did that, we’d be fine. They are not part of the ATF, they are within the fold of the State Department.

      What they do is restrict the flow of products and information, and do so by hanging the costs around our necks. We can blame Bush the younger for this. In one of the fits of governmental budgeting squabbles of the time, he made a deal; the agency could continue doing its good work without hampering the budget, by making it self-supporting.

      That entailed raising the price for an ITAR license from a nominal figure for a real firearms manufacturer, to $2,250 a year. If you are a manufacturer, and anything you make goes overseas, then you have to have an ITAR registration. The problem with this?

      Everything can go overseas, and in typical governmental thinking, if it can, it probably has or soon will, and so you have to pay just to be sure.

      And bureaucratic grasp being what it is, there is always somebody who was previously outside of the need, who they suddenly discover needs to be within the fold. As a result, there are some gunsmithing operations that, to the governmental hive mind, fall within their purview.

      The rule came to us July 22, 2016, and it is §122.1. Basically, only one instance of import or export means you fall under the requirements. But, I’m just gunsmithing you say? They covered that, and here are the ugly points (emphasis is mine):

      2. Registration Required – Manufacturing: In response to questions from persons engaged in the business of gunsmithing, DDTC has found in specific cases that ITAR registration is required because the following activities meet the ordinary, contemporary, common meaning of manufacturing and, therefore, constitute manufacturing for ITAR purposes:

      Use of any special tooling or equipment upgrading in order to improve the capability of assembled or repaired firearms;

      Modifications to a firearm that change round capacity;

      The production of firearm parts (including, but not limited to, barrels, stocks, cylinders, breech mechanisms, triggers, silencers, or suppressors);

      The systemized production of ammunition, including the automated loading or reloading of ammunition;

      The machining or cutting of firearms, e.g., threading of muzzles or muzzle brake installation requiring machining, that results in an enhanced capability;

      Rechambering firearms through machining, cutting, or drilling;

      Chambering, cutting, or threading barrel blanks; and

      Blueprinting firearms by machining the barrel.

      This has been going on for a few years, and I have not heard of gunsmiths being prosecuted (or persecuted, depending on your mood at the moment), but if you do those things for yourself, you are most likely in the clear. But, accept $20 from a friend for any of these operations, and some Inspector Javert of the ITAR could find it within his dark heart to nick you for the registration fee.

      How to avoid it? Don’t be a manufacturer. Here’s what ITAR says about that:

      Occasional assembly of firearm parts and kits that do not require cutting, drilling, or machining;

      Firearm repairs involving one-for-one drop-in replacement parts that do not require any cutting, drilling, or machining for installation;

      Repairs involving replacement parts that do not improve the accuracy, caliber, or other aspects of firearm operation;

      Hydrographic paint or Cerakote application or bluing treatments for a firearm;

      Attachment of accessories to a completed firearm without drilling, cutting, or machining—such as attaching a scope, sling, or light to existing mounts or hooks, or attaching a flash suppressor, sound suppressor, muzzle brake, or similar item to a pre-threaded muzzle;

      Cosmetic additions and alterations (including engraving) that do not improve the accuracy, caliber, or other aspects of firearm operation beyond its original capabilities;

      Machining new dovetails or drilling and tapping new holes for the installation of sights which do not improve the accuracy or operation of the firearm beyond its original capabilities; and

      Manual loading or reloading of ammunition of .50 caliber or smaller.

      Activities limited to the domestic sale or resale of firearms, the occasional assembly of firearms without drilling, cutting, or machining, and/or specific gunsmithing activities that do not improve the accuracy, caliber, or operations of the firearm beyond its original capabilities (as described above) are not manufacturing within the context of the ITAR. If you are not manufacturing, exporting, temporarily importing or brokering defense articles or services, you are not required to register with DDTC.

      The inclusions cover a lot. The exceptions also cover a lot, but are also contradictory. How will this all work out? No one knows, and only by working through our organizations like the NRA, and complaining to our congressmen and women, can it be kept under control or changed.

      As I was wrapping up this manuscript, the word came out that the current administration was planning to change the whole sorry mess. The plan, at least as outlined, was to move all non-military firearms and ammunition to the Commerce Department, removing it from the State Department. The military gear would still be covered by State. This means also the removal of non-military production entities from the purview of the State Department. No ITAR requirement. If so, and if that happens without the opposition stepping in and making a mess of things, then we no longer have to worry about ITAR.

      But nothing is certain until after it has happened, so I’m leaving the above in here. In part because if the plans don’t pass, we’re still covered by ITAR. And if it does pass, then we should not forget what burdens the anti-gunners have been willing to place on us in the past.

      We’re Baaack!

      I have less expensive ways to chop down trees.

      The emperor of China after seeing a Maxim machine gun for the first time. During the demonstration, the gun was used to cut down a mature tree.

      A long time has passed since the first issue of this book. Almost as much time has passed before this book, when I was first thinking I might be involved in firearms as a career. I was in homeroom, in junior High, and I idly thought, Waitaminit, in the year 2000 I’m going to be how old? That’s old. When you’re in junior high, being middle-aged is old. When you are old enough to have voted in nine presidential elections, middle-aged is the peak of health.

      And firearms, rifles? A century-old rifle, one that has been tended to, and looked after, is still solid, useful, not showing its age. Good tools last.

      Man has been referred to as the tool-using animal. I think it would be more accurate to say man is the tool-building animal, because anthropologists have seen other primates, and even birds, using sticks and rocks as tools.

      One category of tool developed by man is the projectile weapon. Before the Neolithic Age (new stone), humans used fire-hardened spears and small-team tactics to clear the Eurasian continent of cave bears. But the more dangerous adversaries, other humans, required better technology. Rather than jump on their prey or their enemy with a club or sharpened tool in hand, humans set about to invent a tool that would secure prey or stop an enemy without the danger of close proximity. After all, who wants to go mano a mano, up close and personal, with a potential dinner source that was more than a ton on the hoof? To do so, the tool needed to launch a projectile. A rifle is the latest manifestation of the projectile weapon.

      A well-made machine will last a long time. The Maxim has been around now for well over a century, and the Russian ones are the Model 1910, if that gives you a clue. Take care of your rifle, and it will last.

      What is a rifle? Different shooters will give different examples. A deer hunter would mention his favorite hunting rifle. A veteran (depending on which war he was involved in) might suggest the M-1 Garand, the M-14 or the M-16. To a benchrest competitor, the only rifle worthy of the name is something accurate to the point of being spooky.

      Rifles come in various sizes, a huge listing of calibers, and may be richly decorated or strictly utilitarian. Characteristics they all have in common are these: 1) A rifled bore. 2) Each launches a single projectile for each pull of the trigger. 3) All are designed to be used with both hands, fired from the shoulder. 4) Accuracy is paramount.

      Can non-rifles have rifled bores? Sure, the proliferation of shotguns with rifled bores for deer hunting is not new. Before the 20th century, a long gun with a smooth bore that had a couple of inches of rifling at the muzzle saw some use. The system, called Paradox, allowed a shooter to use either shot or slug. Today, the screw-in choke-tube system allows a shotgun shooter to use a rifled choke tube and shoot slugs with accuracy.

      Can we call such firearms rifles? No, if for no other reason than to avoid confusing new shooters. Also, the government will not allow us to call it a rifle. A rifle with a bore larger than .50-caliber is classified as a destructive device and to own one requires much paperwork. The few rifles chambered in calibers used in dangerous game hunting are exceptions. To avoid that paperwork, we do not call a 12-gauge shotgun with a fully rifled bore a .70-caliber rifle.

      Otherwise, your shotgun, with its rifled bore for deer hunting, would be in much the same category as the fabulously expensive M2HB .50 machine gun. (A recent auction price on one was over $50,000!)

      Additionally, many competitions encourage handgun shooters to fire using both hands. But a rifled bore and the use of both hands for firing aren’t enough to qualify the weapon as a rifle. Adding a stock may push the gun into that category, but it is also against the law without the requisite paperwork. What about something like a Heckler & Koch MP-5 or Colt AR-15/M-16 in 9mm? The use of a pistol caliber is not enough to exclude these from the rifle group. Rifled bore, shoulder stock, one round per trigger pull when the selector is set on semi. Even the grumpiest curmudgeon will have to admit that the definition of a rifle will stretch to cover a large number of firearms, including pistol-caliber carbines. Rifles in handgun chamberings were common in the 19th century on the American frontier.

      Projectile weapons mean you don’t have to get up close and personal to tag your target.

      No one knows when or why the first gunsmith cut grooves into the bore of a musket. This was long ago, and back then there weren’t nearly as many gun magazines to trumpet the latest and greatest advances in technology every month. Al Gore hadn’t invented the internet. Looking back, it would seem to be an obvious attempt at creating room for the large amounts of fouling that black powder creates. After the first experiment proved successful, the next one would be to give the grooves a twist, to increase their volume. At that experiment the rifle was born.

      It has a rifled bore, it fires one round at a time, and has a scope. Is it a rifle? No. It is a souped-up shotgun that has lost the capability of shooting birdshot or buckshot in a useful way. By the way, this Remington is accurate even by rifle standards, shooting 3-inch groups with ammo it likes.

      Before rifling was invented, smoothbores were the only way to go. Even after its invention, the hassles with using a rifled bore kept it from general acceptance for militaries. That didn’t keep hunters and target shooters from using it. Now, rifling is so common we take it for granted. For granted, that is, until it is worn out, like this barrel, which was then sectioned so we could see what it looks like.

      What does the rifling do for us? By imparting a spin to the projectile, the rifle stabilizes the bullet for its trip to the target. A pitcher throwing a knuckleball has figured out how to throw the ball without giving it any spin. Without spin, the ball drifts off its initial path, buffeted by the slightest breeze or change in atmospheric density. Once thrown, neither the pitcher, catcher, nor hitter knows for sure where it will go. So it is with bullets.

      In places where weapons, firearms, are held only by the upper classes, they are almost always richly decorated. Egalitarian societies afford a market for plain firearms, but we can make ours less than plain, right?

      In the days of smoothbore muskets for military use, an individual was safe from any particular shooter if he was only 200 yards away. Regardless of his skill, the shooter could not guarantee that a fired bullet from a smoothbore would pass within 10 feet of the intended target at that distance. The poor accuracy of muskets lead armies to develop a great deal of faith in the bayonet. Units would maneuver until they were 50 yards apart, unleash a volley at each other and then charge with bayonets. After the initial volley, warfare reverted to the type of combat known since the first phalanx was formed, but without shields.

      So why not issue rifles to the troops back then? That darned fouling again. To ensure a tight fit between the bullet and the rifling — necessary to make sure the bullet would spin coming out of the barrel — the bullet would have to be pounded down the bore. Even using cloth or leather as a patch to seal the bore, the fouling would quickly make seating another shot impossible. The gap between the ball and the bore, called windage, was made generous enough on muskets that without the paper wadding the bullet and powder were wrapped in, the ball would roll right out of the bore if the muzzle were pointed down. The paper wadding both created a marginal gas seal and kept bullets in bores and against the powder charge until they could be fired.

      The most elegant attempt at a fast-loading rifle using black powder at the time of the American Revolution was the Ferguson. The trigger guard was attached to a spiral block that ran through the rear of the rifle. Rotating the trigger guard lowered the block, exposing the breech. The shooter would then put ball and powder into the breech. As the block was rotated up, the excess powder could be pushed into the pan, and the flintlock cocked and fired. It could be loaded faster than a regulation musket, and an experienced shooter could easily hit his target at 200 yards. When demonstrating it to British officials of the Royal War Office, then-Captain Ferguson fired four aimed shots a minute in a pouring rain and hit his target at 200 yards every shot for five minutes straight.

      Lever-action rifles won the West, but they proved to be unsuited for military use. Not that Winchester didn’t try, and various militaries tested. They are fine hunting tools, and capable for defense and competition, however.

      The hide-bound War Office was so under-enthused by this that they ordered 100 rifles and sent the captain off to the Colonies to try them out. Despite their obvious advantages, the rifles were never adopted, and the American Revolution succeeded. Looking back, it is easy to see that if the Royal War Office had taken even a fraction of the money spent on Hessian mercenaries and spent it on Ferguson rifles, the Americas might still under the control of the British.

      The United States did not lack for experimentation in the field of breech-loading rifles. One attempt that got as far as adoption by the U.S. Army was the Hall rifle. Not only was the Hall a breech-loading rifle, it used percussion caps instead of flints and was manufactured on machines (not hand-filed), allowing parts to be interchanged. The breech of the Hall lifted in the front, allowing the powder and ball to be inserted. When the breechblock was pivoted back down in line with the bore and fired, the ball would engage the rifling for spin, and also push some of the previous fouling out ahead of it. The Hall was used for 25 years, finally being retired on account of three main factors: the poor seal between the breechblock and the bore, the fragile stock, and improvements in other designs.

      The next advance in rifle technology came from France. Captain Minie came up with the idea of using a hollow-based lead bullet with a clay plug in the base. The undersized bullet could easily be rammed down over the powder. On firing, the powder gases would rudely shove the clay plug forward, expanding the base, where the bullet would be gripped by the rifling and rotated on its journey. Experimentation soon showed that the clay plug was not needed. This rifled musket was the main infantry weapon in the American Civil War, and some say the horrendous casualty rates were a result of common battle tactics not having caught up with the advances in weaponry. Accustomed to the accuracy and range of muskets, officers and soldiers spent too much time in the open, trading rifle fire with opposing units. It was not uncommon for battle summaries to show units that had suffered 40-, 50- even 60-percent casualties.

      Rifles can be had in various-sized cartridges, from the lowly .22 LR or even a .22 Short, up to these. Here we have an array of hunting cartridges, ranging from the regular (6.5 & .308 on the left) to the large and ohmygod, the .470 Nitro on the far right.

      As an example of how ferocious the fighting could be, at Gettysburg, the 24th Michigan, part of the Iron Brigade, suffered 80-percent casualties on the first day of engagement.

      Advances in rifle technology continued. The next step was the fixed cartridge. Unlike the musket, with separate bullet, powder and cap, the fixed cartridge contained all three in a copper or brass cylinder. The first breechloaders were rimfires, with the priming compound in the edge of the folded head of the case. They were also less powerful than the rifled muskets in use at the time. For military applications, power didn’t really matter for combat. When faced with a unit that could fire 10 shots to their two, the musket-armed soldiers did not care about power. This is a lesson that had to be learned again almost a century later.

      By the end of the 19th Century rifles had evolved into magazine-fed repeaters using fixed ammunition, still loaded with black powder. The last hurdle was the powder. Black powder is bulky for its power, and has a low burning pressure. The only way to get more power is to use a larger cartridge. Black powder also generates a large amount of smoke outside of the bore and residue inside. It is sensitive to moisture.

      The French, again, led the way to something new. They developed a smokeless powder and teamed it up with a new cartridge, bullet and rifle. While the powder was fantastic, the bullet was a sensational leap forward. Instead of being a round-nosed solid-lead bullet, it (after a bit of experimentation and testing) was sharply pointed and turned from bronze. Its shape and velocity turned the usual thrown baseball trajectory of previous bullets into a nearly flat line. The hard bullet penetrated almost all obstacles. Any military facing it would be at a serious handicap. The Germans, long-time competitors of the French and winners of the previous war between them, began their own work.

      In little more than a decade, every major military establishment on the globe, and many minor ones, had changed the rifle they issued to the troops. They had changed from a black-powder single-shot rifle throwing low-velocity lead bullets to a magazine-fed repeater using smokeless powder, many with a high velocity spitzer bullet in the case. Some, the United States being one, changed their rifle more than once.

      In 1892 the United States Army went from the Trapdoor Springfield in .45-70 to the Krag rifle. The Krag was a magazine-fed repeater, and its cartridge was a smokeless round with a copper-jacketed bullet. Still, the advance was not enough. Faced with Mausers in the hands of Spanish defenders in the 1898 war with Spain, the Army wanted better. By 1903 they had the Springfield ‘03 rifle and a new cartridge in the .30-03. Even this had to be upgraded in 1906, ending with the now-legendary .30-06. As far as the military was concerned, such rifles were good enough for the next half century.

      Hunters and target shooters also experimented ceaselessly. The plain bolt-action rifles the military used were too generic, too jack-of-all-trades for these gun lovers. After all, soldiers use rifles to shoot other soldiers. But hunters might use a rifle to shoot game from one pound up to a couple of tons in weight. No cartridge could cover all those game animals. So they went to work. As a result, we have a large variety of rifles and cartridges. Today, the choice is perhaps overwhelming. In Britain, where the expense of owning rifles and going hunting could only be easily borne by the landed gentry, the double rifle arose as a tool for dangerous-game hunting. An outgrowth of the side-by-side shotgun, it offered a hunter the fastest second shot of any action. For those hunting dangerous game, a heavy-calibre double was comforting indeed. Handmade and frightfully expensive, they are rare and beautiful rifles. How expensive? Well, I just checked with a couple of British makers. A Rigby London Best Vintage starts at $21,000. That’s a bolt-action rifle. A relatively plain Holland & Holland double rifle will set you back some $80,000. Truly, if you have to ask, you can’t afford it.

      If you are thinking of gunsmithing, you obviously have an interest in investigating, improving, modifying things. Read. Learn. Ask. Listen. There is an encyclopedia’s worth of information out there to be had.

      The rest of the world went right from single-shot black-powder rifles to bolt-action rifles. Once Peter Paul Mauser had refined the Mauser 1898 bolt-action rifle, his marketing department went out and sold it to most of the governments of the world. The Mauser rifle collector has perhaps the richest field to select from, and some collectors sub-specialize in one aspect of Mauser rifles. The United States, after facing Mauser rifles, designed their own rifle, the Springfield. They took so many details straight from the Mauser design that the U.S. government had to pay royalties to Mauser until joining Great Britain and France, against Germany, in The Great War. Lesson: war trumps lawsuits.

      The sporting use of rifles in the United States went down another path, led by one company, and one designer. Winchester had the exclusive services of the world’s best firearms designer in John Moses Browning. Winchester wanted lever-action rifles. Starting with their improvements of the Volcanic Repeater in 1866, Winchester had had a 20-year run of market success. When Browning offered his services, Winchester accepted, and he designed lever-action rifles beyond compare. While the rest of the world was switching to bolt-actions for hunting, the American hunter was using lever-actions. Plenty accurate for hunting, with power to spare for medium game, the lever-action is faster than the bolt for most shooters. The lever-action was found in most American hunting camps until after the American experience in WWI. There many men were exposed to the benefits of the bolt-action rifle. The lever-action held on, but the accuracy, durability and power advantages of the bolt-action were too much for the levergun. Lever-action rifles, with their tubular magazines, could not use the new pointed bullets. When telescopic sights became inexpensive and durable enough for hunting, the bolt gun surged ahead. The lever-action, with few exceptions, had no place to easily put a scope.

      This is the action that finally got me out of gunsmithing. The Remington 742/1100 trigger mechanism would get absolutely packed with debris, and in the shotguns, with unburnt powder. There was no glamor in scrubbing out the trigger mechanism, and no way to improve it, so it was just scutwork. Twenty years of that, and I’d had enough.

      The size, shape and power of the common military cartridges did not satisfy some hunters and experimenters. At the end of the 20th century we have hundreds or maybe even several thousand cartridges to choose from. Rifles can be had starting in .22 Short up to the immense .50 Browning machinegun cartridge. The .22 Short started life during the American Civil War as a handgun cartridge produced by Smith & Wesson. The Big Fifty saw the light of day as a heavy machinegun and anti-tank round, designed by John Moses Browning for use during WWI. In between are a plethora of cartridges designed to bring down every kind of game. The target shooters did not let any moss grow beneath their feet. From BR-50 competitions using .22 rimfire to the 1,000-yard benchrest matches with rifles chambered in .50 Browning, you can have a target rifle made up in the caliber of your heart’s content.

      Rifles can be single-shots, bolt-actions, lever-action, pumps, self-loaders or double rifles. Each is favored by some segment of the competition or hunting crowd. There are still black-powder rifles, even black-powder cartridge rifles. These are not just for nostalgic hunters, but for serious hunters and serious competitors. Despite the differences in caliber, action type or purpose, they all are intended to be fired from the shoulder at a particular point on a target.

      And what is the measure of success? For some it is an impossibly small group size. For others it is a game animal successfully hunted and brought back. For some competitors, the measure of success is a certain number of hits within a specified amount of time. One standard that all rifles can be measured by is the groups size they can shoot (with human guidance) at 100 yards. When I am discussing the performance of a rifle in this book, I will use one of two standards. All center-fire rifles will be measured by their performance at 100 yards. All rimfire rifles will be measured at 50 yards. So when I refer to a rifle that shot 1-inch groups you will know how far away the target was. Otherwise I will have to write the phrase ...at one hundred yards several hundred times. For most of the 20th century the 1-inch group at one hundred yards (see? I did it all ready!) has been the aspiration of shooters.

      To ask Can your rifle shoot a 1-inch group? is almost to question a shooter’s manhood or veracity. I know shooters who have laminated and targets they have shot. When it comes to the minds of some shooters, accuracy is everything.

      One aspect of change has been in rifle accuracy. In the latge 1990s, it was still common for an accurate rifle to be a relatively expensive rifle. It didn’t have to be made by hand, or custom, but it was going to be the top-of-the-line model from the firearms maker. That has changed.

      The advent of synthetic stocks, in particular synthetic stocks with molded-in chassis bedding systems, and CNC machining centers, has caused a revolution. It is now common for bolt-action rifles to cost almost nothing compared to the old days, and deliver sub-minute-of-angle (MOA) groups. Rifles like the Ruger American, or a host of Savage models that have a retail cost of around $400, can be certain of shooting groups under an inch. Adjusted for inflation, a standard, maybe sub-MOA, maybe not, rifle in 1998 would run you $750 in today’s dollars.

      I think accuracy is important, but not at the sacrifice of comfort, handling ability, and in some cases, looks. To my mind a rifle has to look right, or it just isn’t a rifle.

      Why all the fuss over rifles? For the simple reason that they last. In this age of disposable goods, a quality rifle that is well-maintained is a lifetime possession. On the southern coast of Turkey, a harrowing 22-kilometer drive east of Antalya, is the ancient city of Perge (Pear-gay). Already a going concern by the Third century B.C., it survived through the Roman occupation and much of the Byzantine Empire. Saint Paul preached there after he left Cyprus. If you happen to be there after a rain storm, you will hear the sound of running water. That is the city drain system, still working after the city has been abandoned for 1,000 years. You want quality design and construction? Try to beat that record. A quality rifle that is well-maintained will keep its accuracy for many thousand rounds. For many shooters, 1,000 rounds is a lifetime of shooting.

      A rifle represents power and independence. As Jeff Cooper has remarked, The ability to strike a blow at a distance merely by willing it is a distinctly god-like ability.

      An experienced shooter with a rifle has the ability to decide Hit that, and not the other. for almost anything he can see. Anyone with the will to learn and practice can gain it. It only takes practice, determination, and self-control. Posting a high score on an arcade or computer game is small satisfaction compared to acquiring the skill to use a rifle. But to improve your skill you must have a tool up to the job. A quality rifle is a most valuable tool.

      What will rifles be in the future? While there are many technologies that show promise for improving rifles, there are also stumbling blocks. Any new technology must not only offer real and measurable improvements, it has to fit in with the traditional or expected view of a rifle. One case in point from recent history are synthetic stocks. While a stock may be made of space-age materials, it is shaped just like the wooden one it replaced. Another example is that of the new scopes that have a built-in laser rangefinder. A neat idea, but the problem is, it makes the scope so large it looks like a rifle with a goiter. The moment any manufacturer can get the scope/laser combination down to the size of current scopes they will sell truckloads of them. Any improvements to a rifle must fit the image of a rifle, or they will founder on the rocks of consumer indifference.

      The 21st century should prove to be a grand ride.

      Safety

      My father gave me one very good piece of advice on one of my first trips to the range: Remember this: All guns are loaded, all dogs bite, all snakes are poisonous. Since I watched him load the previously unloaded .22 LR rifle, our dog had never bitten me or anyone else, and my friend Toby and I had caught many a garter snake each summer, I found that information strange.

      It took a while, but I figured it out: if you approach all firearms as if they were loaded, if you assume that any dog may bite you, and that all snakes are poisonous, you will not be surprised when any of those are in fact true. The first time, and every time, you pick up a rifle (or any firearm) to work on it, check it. Make sure it isn’t loaded. I shudder to think of how many times someone came into the gunshops I was working at, with an unloaded firearm. We’d invariably check, and every now and then, just as the owner was saying It isn’t loaded, a round would go flying out as we worked the action.

      Check. Every time.

      Requirements for Rifle Gunsmithing: Skills, Tools and a Place to Work

      I’m a gunsmith. I can fix anything.

      Uttered annually by various tradesmen.

      The wide variety of skills that a general gunsmith must have to solve the problems his customers bring to him is enormous. The level of skill and attention to detail he (or she) needs to satisfy the picky or discriminating customers is gained the same way you get to Carnegie Hall. Practice. Practice. Practice. The general gunsmith might be called on to cut and file metal or wood, sand and finish either or both, solder and file, weld and re-blue. The professional gunsmith will also be required to explain the process, hold the customer’s hand, and properly fill out all of the mandated government paperwork. If you aspire to work full-time as a gunsmith, there is no time to waste, start reading and practicing now. Like that Carnegie Hall aspirant, it will take years to get there.

      If you just want to work on your own guns, for fun, to make a change that might be too expensive if shopped out, or to learn at a leisurely pace, then you can get started simply and work your way up. The majority of work you will do on your own rifle can be done with simple hand tools and a stable bench. Do not be hesitant about taking care of your rifle’s basic needs, or your desires. Even a serious competitor who puts many rounds downrange each year does not need a fully-equipped machine shop just to clean his rifle after each match. The truly serious competitor will clean his rifle that often. The dedicated hunter who is out in the woods every weekend in the season does not need power tools to keep his hunting rifles in top shape. The fancy gadgets and power tools are nice, but not necessary.

      You need a place to store your tools. If you don’t, they will bang against each other on the bench, get nicked and dulled, and you will not be happy.

      Just what is involved in cleaning and maintaining your rifle? You will spend most of your time taking your rifle apart, cleaning it, and putting it back together. Each rifle (and handgun and shotgun) has a limited capacity for how much shooting you can do and how much neglect it will take before it complains. The complaints might take the form of decreasing accuracy or decreasing reliability. When your rifle reaches its limit, it stops working. Each time you compete in a match, or go hunting, or head off to the range for practice, you use up part of that margin. Sort of like the oil in your car. Every time you drive, you get closer to needing an oil change. Go too long, and the engine wears out faster. Going too long without cleaning your rifle means it will also wear faster, and it also may just quit on you. Cleaning your rifle brings that operational odometer back to zero. If you use that margin up completely but don’t realize it, your rifle will malfunction the next time you go to shoot it. If that happens while staring at a big buck through your scope, you will not like it. Failure to clean was the largest single cause of malfunctioning that brought rifles and their owners to my shop. Every time I was faced with a rifle that had failed to fire, failed to cycle, or lost accuracy, each was immediately treated to a thorough cleaning and then tested. More than 90 percent of the time, cleaning solved the problem.

      You need a place to work besides your lap. Fixing firearms in the field might call for that, but you’ll be a lot happier with a proper workbench to work on.

      That situation was also the reason I stopped being a full-time commercial gunsmith. I realized that most of my work, and thus income, came as a result of many hunters putting their rifles or shotguns away after hunting season had ended. Putting them away uncleaned, even wet and already having malfunctioned. And it was up to me, now, in the two weeks left before opening day, to solve the problem. (They always came in at the last minutes, alas.)

      So I walked away. But this book is one result of that decision, so you now benefit.

      The other common tasks you could need or want to do include mounting a scope or receiver sight on an already drilled and tapped rifle, replacing minor parts that are worn, repairing cracked or dented stocks, and tuning the trigger pull on your rifle.

      Mounting a scope is not a difficult job, once you know how and have the right tools. The trick is in getting the scope on straight, securely and undamaged. This does not require expensive tooling, just patience and the right procedure. Installing a receiver sight is simple, if the proper holes are already there in your action. More on these in Chapter Five. To replace small parts, you have to be able to disassemble your rifle, which is part of that cleaning we talked about just a moment ago. Replacing parts with new, improved or just different parts does not take a rocket scientist. Repairing dented, cracked or chipped stocks is straightforward with a few supplies and some practice. On some rifles, adjusting the trigger pull is easy, if exacting, work. Before you flip ahead to the section on trigger work, which seems to consume much of the interest and passion of shooters, let me give you some advice: You cannot improve your shooting solely by making the trigger lighter! Unless you are a serious benchrest shooter, a trigger lighter than 3¹⁄2 pounds will not, by itself, do anything good for your shooting. Unless the existing trigger pull is truly horrendous, practice with a rifle until you have worn out the barrel, then start thinking about a lighter trigger pull.

      One small tool that is a lifesaver to the professional, but one that you might need only rarely, is the frozen-screw jack. Working on over a thousand firearms a year, I ran into many screws that defied normal removal. The B-Square frozen-screw jack allowed me to remove many of them. The ones that broke off, or resisted even the jack, were turned over to my welder. Will you ever need one of those? Probably not, if you tend to your rifle at the end of hunting season and not eleven months later.

      Involved gunsmithing jobs require an investment in both tools and practice. The first time you glass bed a rifle, you will probably have to glass bed it two or three times to get it right. This is not a problem, provided you used release agent and can get the action and stock apart. Why twice or thrice? The epoxy may not get everywhere you wanted it to. Or you didn’t mix enough. Epoxy doesn’t care, just clean the to-be-epoxied surface to remove the release agent, rough it up to give the next application a place to bite, re-apply release agent to the part you’ll be removing once the epoxy sets, and start again.

      If you are replacing your stock with a new wood one, you’ll need files and scrapers. If you are refinishing the old stock or finishing a new one, you’ll need sandpaper and stock finish. To clean up and repoint checkering requires a magnifying visor and checkering files. Refinishing a stock is not an overnight operation. It will take at least a week of regular shop sessions. After you have refinished the stock, you definitely will want to take your rifle to the range and check your zero. It probably has not changed, but who wants to find out on Opening Day? Replacing the trigger on your rifle may require removing wood from the stock. You’ll need the same scrapers, files and chisels that you used for the new stock installation. You may also need drift punches to remove the old trigger mechanism from the action.

      While soldering does not involve a larger investment in tools than these other tasks, it takes more practice. If you are planning to solder sights onto a barrel, it is worth the investment in a scrap barrel as a practice bar. Rather than solder your sight onto your one-and-only heirloom hunting rifle several times before it stays on, heat up the practice barrel. If you think a soldered-on barrel sling swivel stud is the neatest thing since sliced bread (on the right rifle, I have to agree), then solder it onto your test barrel, then try to pull it off. Once you have the technique down pat, you can always heat the stud up, remove it from the practice barrel, and then install in on your hunting rifle. Or buy a new one and install it, instead. The hardest lesson for some people to learn about soldering is that 90 percent of the time involved is spent in prep and setup. The actual heating is almost an afterthought.

      Larger jobs require even more of an investment in tools. Replacing a barrel is something you can do, within limits. Replacing a barrel requires a barrel vise and action wrench, and a bench sturdy enough to stand still for the wrestling. You’ll also need a chambering reamer and headspace gauges. If you are not starting the job with a pre-threaded, chambered and contoured barrel, then you can’t do the job without a lathe. If you want to have your action trued, again you need a lathe. And not just a small hobbyist one, but a large and precise one. If you want such work done professionally, use the information you will gain from this book as a guide in your instructions to your gunsmith. If you need to drill and tap the rifle for a scope mount or receiver sight, you’ll need a drill press. A hand-held variable-speed drill will not be enough.

      If you want to drill holes, you need a drill press. Well, for most jobs. You won’t need a drill press to drill out and plug screw holes in a stock.

      If you are going to work on rifles with a lathe, you need one big enough for the job. Anything that is even just a bit too small, is too small.

      These are also jobs complicated enough that you may want to practice on another rifle before you perform the operation on your pride and joy. Practice is easy. For cleaning, you practice by cleaning. As long as you use a bore guide or muzzle cap along with a coated one-piece rod, you can only harm your rifle when cleaning it by leaving the most aggressive bore solvents in the barrel overnight. To practice disassembly, again, you follow the instructions to disassemble your rifle. Mounting a scope is simple enough that it doesn’t require practice to do correctly. It does get faster the more times you do it. The expense of a practice rifle is small, compared to turning your father’s hunting rifle over to a professional gunsmith after going ahead and drilling and tapping it without practice.

      In case you were wondering, I have seen such rifles. One poor fellow who did this used a hand-held drill. The four holes were not in line, and not straight up and down. The major miracle of his work was that he had not drilled the forward screw hole so deep that it protruded into the chamber! (I have seen holes drilled right into bores and chambers.) I ended up removing the barrel, welding the holes up, and then re-drilling them in my mill. I finished by re-blueing the action and then screwing the barrel back in. All this work cost him more than a practice rifle would have. If you do not want to buy a whole rifle, then buy a scrap barrel and a used stock. Head on down to the nearest gun show, and buy something close. They need not be the exact model of yours, but if you can manage it, that is just great. That does make it easier. A practice rifle, or parts, is less cost, less paperwork if you live where a rifle requires paperwork, and there is no sentimental attachment with just parts. You can practice to your heart’s content or until the barrel and stock are used up. Then buy replacements.

      A lathe that can work on rifles is not something you can pick up and set on a bench by yourself. Even you and a couple of your best buddies can’t do it. So plan on how you are going to move and set up your new tool. Or else.

      The top-end of gunsmithing tools are the free-standing power tools. The drill press is a compact tool that can fit in the corner, or even on a benchtop. For drilling holes in steel, especially the hardened steel of rifles, you can’t beat a drill press. With a drill press and the proper fixture, you can drill and tap scope-mount holes, install iron sights or put an aperture sight on a rifle that didn’t come from the factory ready for one. More important, you can drill them straight, in the correct locations, and in a straight line to the bore.

      Other power tools take up much more room. Even the smallest mill that can handle gunsmithing work will require at least 12 square feet of floor space. If you add a lathe capable of handling barrels, you will require another 18 square feet, and either a concrete-slab floor or reinforcements to a frame floor. What should you consider when looking for a mill or lathe? The mill should have a table at least 2 feet long. Anything shorter and you won’t be able to properly clamp and brace a barreled receiver while you work on it. Avoid mills that do not have micrometer vertical adjustments. A good mill will allow you to move the cutting tool up and down by means of a crank, using a scale as your guide. A cheap mill only allows you to move the cutting head up and down in rough increments. To use the cheap one, you have to fuss endlessly while you attempt to move the cutting head, measure where it will cut, and re-adjust until it is correct. On a good mill, you simply bring the cutting tool down until it touches the top surface, pull the tool to the front or back for clearance, and then lower the tool the precise amount you need to cut. Pull the rotating cutter head across the part, and violà, you have a milled slot, dovetail or flat surface.

      A safe big enough to step into is a beautiful thing. Unless, of course, you don’t have the room to store it, or the money to buy and move it. Cabinets do a lot of useful things, so use them for the things that don’t need a safe.

      Cleaning rifles requires more space than cleaning handguns. You’ll need long, one-piece rods, and it is best if you keep them in good shape. Cleaning rods can be bent or damaged if not taken care of. When you go to the range, pack your rods in a rod case such as this one from MTM.

      Do you need CAD/CAM and power-feed capabilities? No. While they are nice to have (along with a digital readout), you’ll pay more for these features than you will for a big mill, let alone a small one. If you are going to be doing production-like work (multiple firearms receiving the same work/job, for instance) then, OK, digital and power feed are nice. But that is past home gunsmithing.

      A lathe suitable for rifle gunsmithing must be larger than the minimum needed for handgun work. The clearance hole through the headstock has to be large enough for a receiver or a barrel blank to fit into it. You’ll need at least 1 ¹⁄2-inch diameter. The lathe must have a four-jaw chuck. A three-jaw chuck is convenient for fast work, but you cannot center a piece as precisely with the three-jaw as with the four-jaw chuck. When you go to true-up the important surfaces on a receiver, you have to be able to center it precisely in the chuck. The bed of the lathe should be long enough to work on a barrel. I have not seen a lathe yet that didn’t have power feed. Used to cut threads, your lathe does not have to have quick-change capabilities on either chuck revolutions per minute or thread adjustments. You won’t be using it for production, so it doesn’t matter if it takes you a minute or two to change from one setting to another.

      A brass cleaner takes up one square foot of space, if that. Scrubbing the bore of a rifle takes up a lot more elbow room, so plan for it, or suffer banged elbows.

      What about combination tools? By building a machine tool with both the lathe and milling mechanisms as integral parts, you can save a good amount of floor space. But do not trade vertical adjustments on the mill for convenience of shop space. Many of the low-cost combo machines are intended for hobbyist work, crafting parts for model trains, radio-controlled aircraft, drones and the like. Not that those aren’t satisfying pursuits. They simply do not require the equipment that good gunsmithing does. They also may not have the torque to cut steel, as a lot of hobbyist machining involves brass, copper, aluminum and other softer-than-steel materials.
