Milsurp: The Cosmoline Problem

by Sandy Keathley

McKinneyCHL.net

Many military surplus rifles from before 1960, especially WWII bolt-action rifles (Mosin-Nagant, Mauser and others) were re-arsenaled in the 1970s and put away for future wars or emergencies. As a rust preventative, they were often disassembled, the parts covered in a heavy grease called Cosmoline, then reassembled and stored for decades. After the mid-1990s, with the knowledge that those rifles were now effectively obsolete, the respective governments started selling them off to exporters who sold them to American companies for resale to collectors.

Even today, years later, these are still showing up, and new collectors are sometimes unclear on how best to clean them up to put them in shooting condition. When the stocks were either varnished or laminated, the grease is easy to remove, but if not, it soaked into the wood and made the wood tacky. While cleaning up such a rifle is tedious, it is not difficult, and treasure is sometimes found underneath!

This description of the process is based around the typical Mosin-Nagant 91/30, but should be applicable to any milsurp rifle that has been packed in grease. Start by separating the action from the stock.

Disassemble the action, removing the bolt and trigger. Disassemble both the bolt and the trigger group completely. Make notes if necessary, so you can reassemble them properly, but there are many videos online for reference. Wipe off all excess grease from the metal parts with paper towels, put them in a pan, cover them with mineral spirits, and allow to sit overnight. After the parts have soaked sufficiently, remove them, wash with soap and water, rinse, dry, then use compressed air to dry more.

At this point, many collectors will use a buffing wheel to carefully deburr any sharp edges, especially on the bolt parts, but that is optional. I also cut 4 loops off of the firing pin spring, and grind the end flat, to make cocking easier. Ammo in the 1940s required a stronger strike than modern ammo, so this won’t affect anything.

If there is any appreciable time between the final rinse and reassembly of the bolt, give the parts a light coating of Rem oil, as these parts will rust quickly. If not, reassemble the bolt. Some people coat all parts with gun oil, but I have had good results with high-temperature Silicone wheel bearing grease. A little trigger oil or grease at the trigger-to-sear interface is also a good idea. Put those parts aside.

Put the receiver end of the barrel into a bucket of mineral spirits and allow to stand for awhile, then pour some down the barrel. Dry as much as possible, then dry with compressed air. Do not wash the barrel. Put the barrel in a padded vise so you can get to the chamber. This is the part many people miss: any cosmoline left in the chamber will, under firing conditions, turn into a hard, sticky residue that will cartridge insertion and extraction very difficult, or impossible. Use an oversized brass bore brush chucked into an electric drill to polish the chamber, using J-B Non-Embedding Bore Cleaner (blue label). A shotgun mop is useful for cleaning out the residue. Follow this with J-B Bore Bright (red label), and the mop again. Now clean the bore and chamber as usual, with solvent and patches.

If the stock is in good shape, reassemble the rifle. If the action is supposed to be shimmed in the stock, make sure those are in place, so you can torque down the action properly.

If, however, the stock is bare wood (Chinese Mosins frequently are), and grease is soaked in, you have more work to do. Using a paintbrush, paint the wood in small sections with mineral spirits, wait just a few minutes, then wipe clean with shop rags or paper towels. You should see grease coming to the surface. Repeat as many times as necessary. If it is summer, and hot outside, lay the stock in the sun, or in a black trashbag, and sweat out the grease. Wipe down, then repeat. This is very tedious, but the wood will never look good or feel good otherwise.

Once you are satisfied with the condition of the wood, you can do one of these to protect it:

  • Paint the wood with Howard’s Feed-n-Wax. Let dry, repeat twice.This will be invisible.
  • Use Boiled Linseed Oil to create a new but period finish.
  • Use Tung Oil or other finish products to create a nice but non-period finish (only if you are not a collector. Among collectors, this is called “bubba’ing“).

Now reassemble the rifle.

Follow-through for pistol accuracy

by Sandy Keathley
McKinney Firearms Training.com

A shooting topic not often discussed is follow-through, probably because it is so simple. Well, simple in theory, but in the greater scheme of things, harder to prioritize than aiming and trigger work. It doesn’t actually happen until after the shot breaks.

In general, follow-through means to continue the fundamentals of stance and grip all the way through the shot, in the same way that a golfer or batter swings through the ball. If they relax at the moment of contact, the result will not be as good.

Shooters also use the term in a more specific way, meaning to continue to pull the trigger after the shot breaks, until it hits the frame of the gun. Granted, some triggers break very close to the frame, so there is almost no perceptible overtravel. This is generally a good thing, but either way, continuing to pull back until the trigger stops moving forces the shooter to maintain a certain discipline. Otherwise, there is a tendency to react suddenly to recoil, and that can impact the POI (point of impact) negatively. I see student’s fingers jumping off the trigger as the shot breaks. There is no way that can be good.

The next time you go to the range, try moving this up your list of things to remember as you shoot. It may take some practice, but it will help.

 

A frangible essay on choosing the right ammo

People new to shooting (and some not so new) are often confused by the bewildering array of descriptions of handgun ammunition available now (don’t get me started on rifle ammo!). Full Metal Jacket, Total Metal Jacket, Hollow Point, Round Nose, Frangible, Boat Tail, Steel Core, Steel Case, Aluminum Case, Sub-Sonic, +P, +P+, etc.

Let’s simplify this a little. Some of the terminology above relates to specific purposes like hunting or target shooting.If that is your interest, join a forum of like-minded people so you can learn more about those specifics. If your interest is more along the lines of basic marksmanship at 25 yards or less, or self defense, then your options come down to two:

  1. FMJ / TMJ (Full Metal Jacket / Total Metal Jacket)
  2. HP (Hollow Point)

Full Metal Jacket and Total Metal Jacket are similar enough to be called essentially the same.  These both contain lead bullets coated with a copper or zinc alloy, but with minor differences in the manufacturing process that have little impact on the average user.  FMJ/TMJ bullets are less expensive than HP, so they are typically used as range and training ammo, and have greater penetration than HP (sometimes too much).

Hollow Point bullets expand after leaving the barrel, and expand more on striking something. The point is not to cause greater damage, but to minimize over-penetration, which could be a danger to innocent bystanders. A side benefit is greater surface damage to tissue, which translates to greater stopping power. In a defensive situation, a high-powered caliber like .40 or .45 in FMJ could pass right through an attacker and injure/kill someone else. I have a Soviet military pistol that would go through two people and the wall behind them. However, smaller calibers like the .380 might not have enough penetration to even injure someone if they were wearing heavy winter clothing, so some people suggest using FMJ for these smaller calibers.

Both of these types of ammo are also available as Frangible ammo, which disintegrates on contact with anything harder than itself. This eliminates the possibility of ricochets off concrete walls.

Some mention should be made of +P and +P+ rated ammo. These are pressure ratings, indicating that these cartridges generate more force (+P) and much more force (+P+) than normal cartridges of the same caliber. Think of it as steroids for your gun. If the manufacturer of your gun specifies that your gun is approved for those higher pressures, then use them if you want, but only if the gun is made to handle it. Note that there is no industry specification for .380 +P, so these should not be used for that caliber, even if it is available (which it is).

Keep in mind these points about ranges and ammo:

  • Some ranges do not allow uncoated lead bullets, as a possible health hazard.
  • Some ranges do not allow steel-cased ammo, simply for economic reasons. They recycle brass casings, and do not want to sort out the steel.
  • Most ranges do not allow steel core ammo, as it may throw off sparks in the bullet trap and be a fire hazard.
  • Pretty much all ranges disallow tracer ammo, as it is definitely a fire hazard. 
  • A range is generally the cheapest place to get ammo, unless you need something special, so I always buy extra when I go, to keep an inventory for the next run on ammo.

Knowing what to buy, and what not to buy, can save you both money and aggravation.

Home Defense Guns for Ladies

by Sandy Keathley
McKinneyFirearmsTraining.com

Lately, I’ve had several women in pistol classes, and found that some of them had great difficulty in racking the slide on a semi-automatic. That is not surprising; as a general rule, women tend to have less grip strength than men, especially when those women are small-boned, older, or generally not inclined toward athletic activities. Certainly, this is not a problem for many women, especially younger ones, many of whom participate in competitive shooting (or athletics), and hold their own against men.

However, that difference in grip strength should not preclude a woman from being able to have protection at home.  With that in mind, here are some thoughts on guns that all women would be able to safely and reliably operate.

Semi-auto:
The force required to rack the slide is not the same for all models. It depends on the design, and the quality of manufacturing. As always, you get what you pay for. Go to a gun show, and test every 9mm you can. You will find that some are easier than others. Unfortunately, cheaper ones will tend to be harder than more expensive models.  I specify 9mm because larger calibers will tend to have stronger slide return springs. A 9mm is generally thought to have the minimum required stopping power.  You might find that a .380 is much easier to rack, but that may not have enough stopping power to stop a home invasion. Keep reading.

Revolver:
I personally think this is the ideal home defense weapon. True, it only holds 6-7 rounds, instead of the 10-18 of a full-size semi, but if you need more than 6, you have other problems, anyway.  It is idiot-proof; you don’t have to remember how to work it, whether or not there is a safety, which way to take it off safety; just point and pull, and it never jams. The problem for a revolver is that it has much more recoil than a semi, but that is mitigated if the gun is all-steel, has a long barrel, or both.  Revolvers intended for concealed carry are painful to shoot, but an all-steel Colt or Smith & Wesson with a 4-6 inch barrel is an easy shooter, very accurate, and can be managed by anyone. If the trigger pull is hard, just cock it with your left thumb. If you break into my house, and get past my dogs, that is what you will face!

If that is too big for you, consider a revolver in .22 Magnum.  It is much more powerful than a normal .22, in a small package.  A .22 may be lethal, but may not be lethal fast enough to save you.  However, it is better than nothing, and a .22 Magnum will get their attention.

Zippering:
Here is a novel solution; a high-capacity .22.  During WWII, in places like France, Italy, and Poland, partisan guerillas took out sentries at Nazi locations like railway stations and ammo dumps with small caliber pistols like .22 or .32. They were quiet and drew no attention. They were short on stopping power, but the partisans “zippered” the guards. Instead of shooting 3 times at the same place, they shot them 6-10 times in a pattern from the upper chest to the lower abdomen.  Even when it wasn’t fatal, the guard was in serious trouble, as he was bleeding from multiple locations, and could not stop the bleeding, even with two hands.

Several manufacturers, like Ruger and German Sport Guns, make .22 pistols in a large form factor, like a 1911 design, with a capacity of 10-14 rounds. These target pistols are very easy to shoot, and very accurate at 25 yards or more.  The recoil is so little, and the sight-picture reacquisition so fast, that you can hit a burglar 10 times in under 4 seconds. Stopping power is not an issue when he has 8-10 wounds.

Even more solutions:
IF there are no children in the house, get a semi-automatic rifle. S&W makes a .22 rifle with a 25-round magazine. Talk about zippering!  These are even easier to aim and shoot than the pistols. If you want more stopping power, get a rifle chambered in .223 (or 5.56).  Despite the odd numbering system, this is nowhere near a .22; this is a true combat rifle. The .223 has less recoil than the 5.56, but is still manageable, and has all the punch you could ever need.

There are many solutions to the home defense problem, and the Internet can give you much information to maximize your self-defense plan.  Just search.  Write me with questions.

Cleaning your guns

by Sandy Keathley
McKinney Firearms Training.com

While it might not seem that this is a suitable topic for a blog on shooting tips, it actually is. It doesn’t make much sense to practice accurate marksmanship, only to have the gun fail to work in a defensive situation. The issue is not so much the cleaning of carbon from the chamber and bore, but lubricating the moving parts. Revolvers are much less affected by this, but semi-automatics have a delicate balance between the backward force imparted by the cartridge firing, the forward force of the return spring, and the friction in the slide channels. That balance is easily upset, by using a low-powered cartridge, the wrong return spring, or allowing dirt buildup around the slide.

Cleaning kits can be bought inexpensively at all gun stores and outdoors/hunting stores (Cabela’s, Bass Pro, Gander Mountain, etc.), or online. They will generally include solvent, gun oil, patches of various sizes, a T-handle cleaning rod, and a selection of rod ends for pulling patches through the bore. Not included are the brushes (brass or nylon) used for cleaning the bore, as these are caliber-specific, and need to be bought separately.

Revolver. This one is easy. Swab each of the chambers in the cylinder, and the entire bore (barrel) with a patch soaked in solvent. Run the proper-sized brush through each several times, then follow with patches until they no longer show discoloration. Wipe down both ends of the cylinder, and any other places inside the frame you can reach. Revolvers require very little lubrication, but you can put a drop on the ejector rod and one where the cylinder revolves in the yoke.

Semi-auto. These must be broken down a little. The first step, of course, is to remove the magazine and clear the chamber. When you hear that someone said “I was just cleaning my gun, and it went off“, they are lying. They are trying to explain why they shot someone. You can’t run a bore brush through a chamber that has a cartridge in it. Duh! Don’t be an idiot.

The next step requires your manual. If you don’t have one, they can be found online. The process for breaking down the gun is similar for most guns, yet different enough that you should not try it unless you have the manual, or your gun is identical to another with which you are familiar. Once you know the trick for removing the take-down lever (pin), the slide will come off. The main part of the gun can be put aside. Remove the barrel from the slide. You will be cleaning the grooves in the slide, and the inside of the barrel, just like with the revolver. On reassembly, be sure and oil the grooves in which the slide moves. Instead of gun oil, you can also use gun grease; that is just a personal preference.

Once reassembled, rack the slide several times to test the action. If you did anything wrong, you will find out now. If it passes, put it away, and you are now good for another two or three range trips.

New gun in the collection

by Sandy Keathley
McKinneyFirearmsTraining.com

Well, not exactly new. In keeping with my collection of Soviet-bloc Cold-war weapons, I recently acquired a 1953 Romanian TTC military sidearm.  It is a semi-automatic, chambered in an unusual caliber: 7.62×25, the so-called Tokarev round. This cartridge, and the pistols that fire it, were developed in 1930 by a Russian engineer named Fedor Tokarev to replace the aging Nagant revolver.  The Tokarev cartridge contains a .30 caliber bullet (smaller than a .32), but is much longer than a 9mm.  The result is a bullet that develops a muzzle velocity of 1500 FPS, which is considerably more than a .45, and comparable to a .357 Magnum. I wouldn’t recommend shooting a burglar in your apartment with this beast, as the bullet would go through the burglar, and probably through the adjoining wall!

Those of you who have studied wound ballistics will know that the most important factor in stopping power is not the size of the bullet (caliber), but the speed it travels. That’s why a .357 Magnum has greater stopping power than a .45, even though it is considerably smaller.

After WWII, with the new political alignments in Europe, the Soviets “encouraged” their partners (including Romania, Poland, Hungary, and later, China) to build their own weapons, but using Russian models. The Romanian TTC is an exact copy of the Russian TT-33. The Romanians wanted to chamber it in 9mm, as that had become the de facto standard, but political factors forced them to adopt the Soviet standard, 7.62×25 (Russian combat rifles had used the 7.62×54 for decades). Tokarev ammo generally can’t be bought off the shelf, but it is still made by some major European manufacturers (Sellier & Bellot and Prvi Partizan), and is readily available by mail and at specialty dealers.

This pistol is incredibly loud, and has significant recoil, as it essentially fires a small rifle round from a pistol, but the long, all-steel gun balances that recoil well.  The accuracy is very good, and it fired 30 rounds flawlessly, but the gun will require a lot of break-in, as it has been arsenal-refurbished, and the trigger pull is very stiff.  This would have been a very stout officer’s sidearm, and lethal at a considerable distance.  It came with a 1950s leather holster, with space for an extra magazine.

Buying your first handgun

by Sandy Keathley
McKinneyFirearmsTraining.com

While some people buying a first handgun may have learned to shoot without owning one (in the military, with family, or just taking a pistol class), it is likely that the majority of people shopping for their first gun are new to this world. The challenge for them is deciding what to buy, from the thousands of models available. They read articles, ads, and reviews online until they’re cross-eyed, go to a gun shop or a gun show, and talk to friends. Everyone they ask, friend or dealer, has a different opinion. The dealer may recommend what he has in stock; the friend will recommend what he shoots, but he may not have shot that many pistols. They are all different; all have upsides and downsides.  What to do?

Why do you want a gun?  Many people will recommend that you first decide the purpose for a gun. Common answers are “home defense”, “car/truck gun”, “concealed carry”, or even “protect sheep from wolves”. One lady told me she liked to hike in rough country, where she might encounter wolves or even bears. Those are mostly good candidates for a handgun. Protecting sheep from wolves, not so much. I would get a stout 30 cal bolt-action rifle with a scope for that. Actually, I would use a 1943 Soviet sniper rifle, but that’s just me.

Leaving that aside, the other reasons would steer you (or me) to different guns: a .357 Magnum revolver for the hiker, a 9mm or .380 sub-compact semi-auto for concealed carry, a .45 for the home, etc.

Learn to shoot first. I’m going to offer another, perhaps controversial, opinion. Small guns are more difficult to shoot for a beginner, for a variety of reasons. Light-weight guns, ditto. Larger calibers, like .40 cal or above, same answer. I would rather see someone get a full-size, fairly heavy 9mm pistol, maybe a 1911-style, one that is easier to shoot well. Learn to shoot it well, then, if the size is not appropriate for your purposes, get another. Does that mean getting two guns? Eventually, yes, I’m afraid so. The fact is, very few people have just one handgun, and many of the ones who do, have the wrong one (for them).

Over-achiever. Call me an over-achiever, but being able to hit a man-sized target at 5 yards is not good enough for me. My goal was to hit a paper plate at 15 yards, and a man-sized target at 25 yards. Once there, with longer guns, then time to reset that goal with shorter guns.

Larger guns help smaller guns. Having recoil problems with your pocket .380? The best answer is to borrow or rent a .45 for an hour. Then the .380 will seem easy. That is the whole point of this essay. Learn to shoot first, with a gun that helps you, even if it is not suitable for your purposes. Then leverage that experience on to a gun that is. You will find it a much flatter learning curve.

The Top 5 things to know when carrying concealed in Texas

by Sandy Keathley
McKinneyFirearmsTraining.com
McKinneyCHL.net

Texas is one of the more gun-friendly states in America (despite not having open carry), and the laws are probably very similar to many other states, but it may be useful to the traveler from outside Texas to have a quick synopsis of things of which you should be aware.

1. Weather
In the summer, it can be very hot. 105 is not unusual, and temperatures above 110 have been recorded. In 1980, Dallas had 40 days in a row that hit over 100 degrees. Wearing a suit or coat is insane, so have a backup plan for concealment. In the winter, you might expect (and get) temperatures in the 20-30 range, yet even in Feb you might see a sudden unseasonable warm spell of 75 degrees. When traveling, always have a backup plan.

2. Vehicles
Texas does not require a license to carry a gun in a vehicle, but with or without a license, it must remain out of sight. It does not have to be in a lock-box, but out of sight.


3. 30.06
This curiously numbered statute is the part of the Penal Code that allows any private business to declare themselves a gun-free zone. As to why anyone with a brain would do that is beyond me, but they exist. Almost all hospitals and surgery centers do post this notice, as well as Cinemark Theaters, Chuck E. Cheese restaurants, and a few others. Otherwise, it is not really common. Signs are sometimes seen that do not contain the exact verbiage required by the statute (sometimes not even close), but it is not well-advised to try to split hairs with police over this. Due to the way the law is written, you will probably still go to jail, at least overnight. Note: gun shows are almost always posted.

4. 51%
Any business that receives 51% of their revenue from the sale of alcohol for on-premises consumption must post this sign. Carry is forbidden there, whether or not you are drinking. This is mostly bars. Some restaurants fall under this category, but most do not. Note that liquor stores, grocery stores, and convenience stores also do not, as their sales are not for on-premise consumption. They have to post a sign stating that unlicensed carry is a felony, etc., etc., but that does not apply to a license holder.

5. Off-limits by statute
These would be locations that are automatically off-limits, with no posted notice required. Some are mandated by Federal law, while others are state law. This includes

All schools and colleges, all levels (except parking lots, for non-employees)
Any location where school athletic events are staged, all levels
Federal buildings and Post Offices
Courthouses and court rooms (state or Federal)
Secure areas of airports
Places of execution (on execution days)
Voting locations (on election days)
Horse/dog race tracks that allow pari-mutual betting
Sporting events

Note that facilities owned by state and local government (other than courtrooms) CAN NOT be off-limits (the State Capitol, convention centers), except that government meetings can be posted by request.

Range Etiquette

by Sandy Keathley
McKinneyFirearmsTraining.com


Like most communities of like-minded individuals, the gun community has its own rules of protocol and accepted behavior. For obvious reasons, much of that revolves around shooting, much of which occurs at shooting ranges. While a range will always have a list of its rules for visitors to read, the legalese doesn’t always translate well to the standards of behavior expected by many more experienced shooters. Range etiquette is not just rules, but behaviors that will help you avoid the disdainful glances from other shooters. After all, there are many things that are not illegal, yet are considered gauche.

There are some differences between indoor and outdoor ranges, so let’s look at standards that are common to both, then break out the variances.

Always point the gun downrange. This is Job 1, but it’s not always clear what it means. Of course, point it downrange when shooting, but also when not. Treat the muzzle like a needle on a compass that always points to magnetic North. Never allow the muzzle to point anywhere else, even when casing, uncasing, loading, unloading, racking, etc.

Keep your finger off the trigger. The big one. I see people at the range all the time (not just new shooters), racking the slide with their finger inside the trigger guard. That is dangerous, and perhaps the biggest mistake on the range. It can get you ejected.

Bring the gun to the range unloaded and cased. It won’t go off in your range bag, but a mistake while uncasing a loaded gun could be a tragedy. Wait until you are on the line to load it.

Always use eye and ear protection. If you think this needs explanation, you are not ready to go to a range.

Keep all your stuff near you. If your range bag is several feet behind the line, you may end up carrying a gun to or from the bag. See the next item.

Never carry a gun away from the bench uncased. If trading guns with someone, leave the guns and trade lanes. In case of a malfunction, clear and case the gun before leaving with it. People do not want to see someone wandering around the bay with a gun at their side.

Never draw from a holster. Some ranges have special facilities for this, but most don’t allow it. It can be dangerous, especially when re-holstering. Go out in the country to practice that.

Never shoot at someone else’s target. Does that really have to be said? Evidently so.

Never shoot at the device that holds the target. Ditto. Paying for those repairs makes range fees go up.

Never bring to the range tracer ammo or ammo with steel cores. These are fire hazards, and have started major fires at ranges. Many Safety Officers check for this, but sometimes they get busy. Don’t be an idiot.

Do ask for help. If you have a malfunction or jam, trouble with the target trolley, or just need to ask something about how your gun works, range personnel will always help. More than that, the shooter on the next lane will probably help. Gun people are very willing to assist others, to the extent that they can. By the same token, don’t be offended if another user points out that you are doing something dangerous. Everyone needs to watch out for others on the line, in the absence of a Safety Officer.

Outdoor ranges.

While indoor ranges typically have targets that can be moved individually, on a trolley system, outdoor ranges generally have targets that have to be moved or replaced manually, by going ahead of the firing line. For safety, you must wait until the RSO (Range Safety Officer) calls a periodic cease-fire. At that time, you are expected to remove magazines, lock the action open, lay the gun down (pointed downrange) and step back several yards while the RSO inspects each weapon. Once that is done, the range will be declared “cold”, and you can move downrange to replace or move
targets. On returning, you have to stay away from the bench. When everyone is back, the RSO will declare the range “hot”, and firing can commence. It is important to follow the RSO’s instructions carefully and literally, else you will be corrected. That is embarrassing.

Range etiquette not difficult, and it is part of the discipline that is required to shoot safely among a group of people, and have fun at the same time.
