As an avid competitor in IPSC and local pistol competitions, a number of years ago I decided to reload ammunition on my own.  I felt this would pay for itself over the long haul as well as allow me to work up loads that would have the correct power factor, accuracy, and excellent feeding for competitions, not to mention self-defense.  In addition, after the passing of the Brady Bill, I took on another task of casting my own bullets with the possible specter of either the government removal of ammunition from store shelves or some other legislative means of taking away guns via restrictions with powder, USEPA restrictions with lead and so on.  I wanted to be relatively self-sufficient and have an asset that might be marketable in light of a possible economic, social, or political meltdown.

T his discussion will specifically address bullet casting 185 grain semi-wadcutter bullets and 200 grain semi-wadcutter bullets for the .45 ACP or “melting lead for the meltdown.”

It helps to have a good source of lead and other metals for the “melt.”  The “melt” is what you have in your melting pot to pour bullets.  This comes from your source and supply of metal.  My brother initially supplied two 5 gallon buckets of discarded used wheel weights from the garage he worked at.  In addition, I have purchased on eBay “linotype” which makes a very good melt for cast bullets.   Wheel weights generally have an appropriate mix of lead, tin, and other metals that give a reasonable hardness with cast as bullets.  The ratio noted in the Lyman manual indicates the following alloy and the hardness factor for their own recipe called Lyman #2 alloy: 90% lead, 5% tin, and 5% antimony giving you a hardness factor of 15 (Brinell Hardness Number or BHN).  The linotype mentioned (which comes from the printer’s shop and generally available via eBay) has a hardness factor of 22 due to having more antimony and a bit less lead.  The wheel weights had to be sorted and melted into ingots and put aside until there was enough to start the casting process.  I also had to weed out any weights that smacked of zinc as this will be a negative factor in casting.

My bullet casting started with primal tools and has worked to a little bit more efficient tools.  I started with a cast iron pot, ladle, kitchen stove (really makes the wife happy) and a Lyman #2670460  200 grain semi-wad cutter mold with a four bullet capacity.  The handles are RCBS which work with the Lyman mold.  My second mold is from Magma Engineering which can be checked out at their web site, a 185 grain semi-wad cutter bullet with a two bullet cavity.  Again, I went with RCBS handles.  

Other tools of the trade include: a hickory handle to break what is known as the sprue, a stainless steel spoon for stirring into the melt either Brownells Flux or a pea size chunk of paraffin wax, a heavy duty kitchen glove or mitt, a heavy duty box to plop newly cast bullets into, and a small pan to place excess sprue into.     

Later, after learning some of the basics and wanting to speed up the casting process I graduated to a Lee Pro 20 Series melter.  There are numerous other melting pots on the market that you might check out at Midway USA or other outlets.  I also picked up Lyman melt thermometer to keep track of the temperature of the melt. But, wait, there’s more!  So, to get started with your melting, you need the following:

1. A 2 cavity or 4 cavity bullet mold (mine are the Lyman #2670460 4 cavity 200 gr. Semi-wad cutter and the Magma Engineering 2 cavity 185 grain semi wad cutter).
                 
2. A pair of RCBS mold handles.
                 
3. Lee Pro 20 Series Melter

4. Safety Equipment: Face shield, apron, long sleeve shirt, gloves, and leather boots
                 
5. Miscellaneous: hickory handle, stainless steel spoon, flux/paraffin wax, kitchen glove, and container for bullets.

Those bullets have to be sized and lubed before they can be reloaded.  This is what I wanted to be able to do.  So, the additional tools you’ll need for the sizing and lubing from your manufacturer of choice, I picked a:

1.  Lyman 450 Bullet Sizer/Lubricator

2.  A Midway Lube Heater (which is mounted under the Sizer/Lubricator)

3.  Lube (Alox or Blue Angel -- the latter needs the lube heater)

4.  Lyman top punch sizing die.  The sizing die and top punch size the bullet (in my case to .452 diameter) to the right diameter for the .45 ACP.

I might add it would be helpful to have a manual handy for the whole process such as the Lyman Reloading Handbook.  A handbook for bullet casting should also come with the bullet sizer/lubricator.  There may be something on YouTube as well; however, I have not checked it out.  In addition, I believe there are videos available to assist you.  I have never used or purchased a video but I think it would be helpful.

So, in a well-ventilated workspace, let’s fire up the Lee Pro 20 melter.  I take the ingots that I have made from the wheel weights and/or the linotype and place them in the melter.  There is a gauge on the melter for the approximate temperature and as you become better experienced you will likely be able to drop the melt thermometer.  You want at least 650 degrees and you want a small fan or a vent hood to dispel any lead fumes.  As the ingots slowly melt, add a teaspoon of flux or the pea size piece of paraffin wax to draw the dross to the top of the melt.  Skim off the dross with your stainless steel spoon (and duct tape the handle end to prevent burns) and discard in something non-flammable. While the ingots are in the pot melting, you will want to heat your bullet mold.  I just set mine on the edge of the melter and rotate it to try to heat it with some uniformity.  When the melt has reached temperature, place your mold under the valve or spigot where the melter will allow the melt to flow out and lift the handle to allow the flow of the melt.  As you fill each cavity let an additional amount pour to have a good break when the sprue plate is popped open.  At the top of the bullet cavity is the sprue plate which has to be hit to shear off the excess melt providing a nice flat base on the bullet.  Once the sprue plate is knocked back with your hickory handle, break the mold open, gently tap if needed, and drop the bullets into a non-flammable container. 

Use your spoon to scoop up one of the bullets to see if it is well formed.  Generally, it takes me maybe 4-to-5 pourings to get nicely formed bullets.  This is due largely to the molds having to get up to temperature. When the bullets are coming out well formed then continue the process of pouring, breaking the sprue plate open, dropping the newly molded bullets, and so on.  If you notice your bullets coming out looking “frosty” then you will need to back off on your temperature or let your mold cool off a few minutes. When a bullet “frosts” it becomes brittle and that isn’t good while moving down your gun barrel at 850 fps.  Keep constant check for that.  50 pourings with a four cavity mold will give you 200 bullets.  You can get this in maybe an hour or more depending on your skills and experience.  As you  consume the melt, you will have to put in more ingots.  This will take a few minutes to melt and come to temperature.  I like to size and lube during these breaks  while my ingots are initially starting to melt.  I try to finish up my bullet casting when the depth of the melt in the melter is about an inch deep (measured by my spoon) and after I have gone thru enough melt to cast 400-500 bullets.  Time to unplug the melter and let the remainder cool down. 

With free wheel weights a good bit of money has been saved.  The equipment will pay for itself.  The time is well used and for me a bit therapeutic.  I like seeing things come out right that I actually had a part in.  A box of 500 bullets is now close to $50.  When I was competing regularly I was going thru 300 bullets per week which isn’t a lot.  I still was knocking at the door of A class in IPSC with the 300 rounds per week in practice.  So, for me, buying 300 rounds a week at Wal-Mart was not going to work.  Casting and reloading my own ammo has worked out well.

Now, we’re not quite finished yet since the cooled bullets have to be sized and lubed.  Generally speaking, you would want to “slug” your barrel to confirm the size you need to get your bullets to.  I didn’t do that and never have had a problem.  I just made sure I had the .452" top punch/sizer.  I am assuming you have your sizer/lubricator and heater mounted at this time so I am dispensing with further instructions.  If you use Lyman Alox or other lubes that don’t need heating then don’t plug the lube heater in.  If you go with “Blue Angel” hard lube then you will need to crank up the heater, place your lube in the lubricator and run a bullet thru.  You will likely have to adjust the sizer/lubricator to ensure the bullet is being completely sized and that the bullet lube fills the lube groove on the bullet fully.  You can crank out the sized and lubed bullets and place them into whatever container you’d like.  I have used Betty Crocker icing containers, small boxes suitable for holding 300-500 bullets, and a large plastic canister that held psyllium husks from NOW foods.  These bullets are ready for reloading, storage,  packaging to sell or barter. 
  
In conclusion, this has been a basic how to to melt for the meltdown.  You will have to experiment as you go along.  Talk with others who cast bullets as well and you will get tips and pointers that will be helpful.  I can’t leave without leaving a couple thoughts as to a spiritual side of bullet casting.  One is that when the lead ingots melt, there is a tremendous heat and I actually ponder a place called ‘hell.’  I cannot imagine being there and as a child asked Jesus Christ to forgive me of my sin and trusted Him as my Savior.  Thankfully, I will never have to face an eternity as hot or hotter than the melted lead in my melter.  Second, as a believer, Proverbs talks about the “fining pot and the furnace.”  It can apply to the lives of Christians who are going thru the “heat” of trials in this life.  After you skim off the dross from the melt, the melt is mirror-like when you look down into it.  You can actually see your reflection.  It makes me think that when the “heat” is on in my life, the Lord wants to skim off the dross and see a reflection of Himself as He looks on.  And, He wants the world to see His reflection as well.  God bless you and keep you safe.  May he give us all the wisdom we need in the event of a “meltdown.”

Dear Jim,
To add to Pat Cascio's comments on AR rifle construction, I thought I'd share the following:

This document explains the criteria.

This chart puts them all together

One of the very critical components is the buffer tube on carbines.  The aftermarket tubes are of 6061 aluminum, versus 7075, and are milled, rather than being hammer-extruded.  They are about half as strong as mil-spec, and have less gripping surface on the threads.  This is probably one of the most critical areas of failure on the rifle.

Please note that Knight's Armament is not mentioned on this chart, but they will happily detail the internal redesign they've made that from all tests and reports is superior to the standard design and materials. However, it is also much more expensive.

The AR bolt carrier group is easily replaceable, but it's worth the extra money for the stronger components of tougher alloys to increase operating life. In addition, I differ from most and always recommend the hard chrome finish on the bolt carrier group.  While on active duty in the 1980s, I got to handle both parkerized and chromed groups side by side, and there was no comparison.  The Army went away from the chrome for several reasons, one of which was cost, but I believe this was a huge error on their part.  The chrome finish is tougher, more durable, has greater natural lubricity.  Heat treated and parkerized steel has a static coefficient of friction of about .8 (1.0 is the baseline).  Hard chrome has a coefficient of .05.  It actually performs better with minimal lube, as the surface tension of the liquid increases drag.

I will disagree with Pat on one point:  It is certainly possible to get a very accurate and functionally reliable AR in the $600 range, but it cannot be as durable in the long term as one built with better materials, which will always raise the price.  I would advocate an inexpensive rifle over none, but when opportunity presents, it should be assigned practice, range and backup duties, with better rifles taking the SHTF role. - SurvivalBlog Editor At Large Michael Z.

SurvivalBlog readers may recall that I've previously tested the Triple Eight Professional SOL Knife.  The 888 SurvivIt Tool is more versatile, and a bit more robust. The blade is AUS8 steel, and the handle is epoxy-painted steel.  It's assembled with machine screws and good quality pivot and fittings, so maintenance and repair is easy, though I don't expect it will need much.

The edge was not quite as sharp as I like, and I had some trouble cutting leather thong with the hook.  The serrated section, however, as short as it is, zips through heavy nylon, leather and plastic easily.

The handle is tiny, but comfortable enough even in my largish hands, and is well-designed.  I tested it in a hammer grip to chisel, in a standard grip to shave and whittle, and in a side grip for both drawing cuts and scraping. 

The edge geometry is excellent, and I was able to jab the blade well into various woods, both in the woodpile and on treated lumber in the shop.  It sliced into wood corners easily, sawed twigs, and scraped tape, bark and leather.

The mechanism is strong and sound and remains in place while the knife is held.  Keep in mind that there is no guard.  This is a compact tool, and its diminutive size means there are some compromises necessary.  Once you have a good grip, it remains easily in hand and is safe to use.  Just don't get careless.

In addition to the belt clip, there's a convenient thong hole for either neck carry, or just for a retention cord.

The suggested retail price is $34.95, but is usually available for less at most retailers.- SurvivalBlog Editor At Large, Michael Z. Williamson

JWR:
There is a great reference for barrel cleaning and break-in procedures that is available free on web, courtesy of Krieger--a well known barrel maker. It is a reference worth printing out. - J. McW.

Jim,
Just a quick note on the letter about home made gun solvent. He mentions that "All of these solvents comes in colored glass to keep out sunlight."
He goes on to mention hard liquor bottles as a possibility. My problem with them is their size. You can get the "pocket flask" but most often you see 750 ML and 1.5L bottles. Common old beer bottles will work just as well, may be easier to find, and will hold more manageable amounts.

For labeling such recycled bottles I like to use a medium Sharpie [permanent marker] and plain white paper with a wrap of clear shipping tape. Go all the way around the bottle with at least an 1/8 inch over lap onto the glass and between multiple rows of tape if needed. The tape is tough, UV resistant, and cheap.

 

James,
In the home-made gun solvent article, hydrogen peroxide is mentioned. It shouldn't get near any aluminum parts as it can induce corrosion, pronto. We have been advised in aviation facility where I work that any solvents and cleaners used on aluminum surfaces should specifically state whether it can be used on aluminum and absolutely should not contain peroxide. I'd hate to see a reader clean a nice lightweight 1911 with aluminum frame with something containing peroxide, only to get pitting and corrosion as a result.
 
BTW, I've picked up the Kindle version of "Survivors" and gifted one (so far) as well. Thanks for SurvivalBlog and all you do. God Bless, - G.R. in Texas

Jim:
One needs to avoiding cleaning [complete] polymer guns in an ammonia solution, as the ammonia will do irreparable damage to the plastic. - J.D.F.

JWR Replies: Those two warnings should not be ignored. Do not use this cleaner for Glocks, Springfield XDs, or other polymer-framed pistols or guns with any aluminum parts unless you have removed the barrel and are cleaning the steel parts nowhere near the gun's plastic or aluminum parts!

Sir:
I'm a benchrest shooter and gunsmith, and I use quite a bit of cleaning solvent. When I used to buy it, I would buy it by the pint bottles. While not terribly expensive, it was still a cost. I asked fellow shooters what they used and most did as I did, buy it. Then I asked a very successful shooter what he used and he said "my own brew"! Just what I wanted to hear. He was nice enough to share his brew mixture, and that is all I've used since.

There are a couple main things you're trying to do, or combat, with cleaning solvents: carbon fouling and copper fouling. Carbon is the byproduct of the burned powder. Copper fouling is bullet jacket material that has plated itself in the bore. If you used lead bullets, you would have to contend with that, but I don't, so this is targeted for using copper jacketed bullets. Carbon is probably the toughest to get rid of, it is extremely hard and stubborn. It can build up and degrade accuracy. The best way to keep it in check is to not let it build up in the first place, by cleaning when the barrel is new and not shoot a hundred rounds before cleaning. But sometimes you have to deal with what you have, now. Copper fouling does the same thing, it builds up in the barrel and just keeps getting worse.

If you get a used gun and it is fouled pretty bad, you may want to use something other than this cleaner at first. Abrasive cleaners (JB's, Iosso) do a good job of getting through this stuff. It takes some elbow grease to work it back and forth and you need to keep changing patches, but it will get through it. Once the rough stuff is gone, then using this mixture cleaner will get the rest. [JWR Adds: The general consensus is to avoid abrasive bore cleaners, unless it is absolutely necessary. In my opinion, on a very pressing emergency would dictate that. Otherwise, nothing more abrasive than a brass bore brush should ever be used.]

[JWR Adds This Warning: All of the usual precautions for handling caustic and flammable fluids must be taken, such as wearing goggles and rubber gloves.]

So how to make it? There is an initial expense to this, but it goes a long way and my formula makes quite a bit. First, go to a GM car dealer, and buy a few cans of "GM Top Engine Cleaner", ask if they have it in the metal can. It is my understanding the newer Top Engine Cleaner comes in a plastic bottle, and may not be as effective. I'm not sure since I have the metal can cleaner. I would think it would still work okay. It comes in a 15 ounce can and it the basis for the cleaner. It has the chemicals in it for fighting carbon deposits. [JWR Adds: Very similar products are sold under various brand names as Upper Cylinder Lubrication & Injector Cleaner.] You can scale how much solvent that you want to formulate in a batch by the number of cans of Top Engine Cleaner that you buy. The second ingredient will be the hardest to get, and that is strong ammonia. Ideally, find a blueprint shop, large printing shop, and ask if they have 28% ammonia. It comes in a gallon jug. Trust me, don't sniff it, it will clean your sinus' like you've never known. The next ingredient is Marvel Mystery Oil that you can get in most auto parts stores. Lastly is regular Hydrogen Peroxide which you probably already have.

Get a colored glass container, brown, blue, something that is tinted. All of these solvents comes in colored glass to keep out sunlight. Some of the whiskey/bourbon/scotch bottles are brown and work fine [if prominently labeled "Poison" and with a description of the contents.]. Shake and pour in a 15 ounce can of top engine cleaner. Measure 25 ML of ammonia, 5 ML of peroxide and 5 ML of Marvel Mystery Oil and dump it all in. It won't explode, don't worry. Shake it all up and you have a top notch bore cleaner. The Top Engine Cleaner goes after carbon deposits, the ammonia and peroxide attack the copper fouling, and the MM oil acts like a penetrating oil that helps get under the deposits and keeps the bore conditioned.

The ammonia reaction to copper fouling will turn a white cleaning patch blue, or rather the patch will pick up the blue tint from dissolving the copper. It a good tell-tale indicator of how well the barrel is cleaned. You don't have to get every last bit out, but if there are heavy deposits, it will be a deeper blue, when getting fairly clean, it will be a much lighter blue.

I use this on all of my rifles, and for pistol barrels. Most of my rifles are bolt actions, and cleaning is easy, but use a bore guide to keep the cleaning rod from damaging the barrel. If you have an lever gun or semi auto, you may have to clean from the muzzle. Beware that you can severely damage the end (what is called the crown) by letting the cleaning rod drag over the edges of the barrel end. I would recommend getting a "coated" cleaning rod to help with this, but still, go slow and watch the rod position to keep it centered in the barrel.

There are a couple substitutions I've heard that you can use Mercury Quicksilver Gear Lube. It is a product made by the Mercury Outboard Motor company. It must have the same properties as the Top Engine Cleaner". The ammonia is the toughest to get, and may even have some restrictions now, given the state we're in. You need the strong stuff. The 28% I referenced is what I have. Most blue print shops now use large copy machines instead of the old "blue prints" where the ammonia was used. You may be able to find some strong ammonia at commercial janitorial suppliers. You can substitute Kroil Penetrating Oil for the Marvel Mystery Oil. Kroil is a penetrating oil, not exactly easy to find but it is available. - W.S.

One of my consulting clients recently bought several Bed Bunker gun vaults and I had the chance to examine them. This product is an unusual horizontal home gun vault design that replaces your bed's box springs. These vaults have two major advantages: 1.) They don't take up any more floor space than your current furniture, and 2.) They will probably be overlooked by most burglars that are in a hurry. (And statistics show that most burglars are in a hurry. Typically, they are in a house for less than five minutes. The bad guys can't attack a safe if they don't know that it is there.)

I was pleased to hear that these vaults are manufactured in Spokane, Washington. That minimizes the shipping costs for those who live in any of the American Redoubt States, and you can feel good that you'll "Buy American". In this case, you'll even "Buy Redoubt".

Bed Bunkers are built with welded 10 gauge steel in the body and a 1/4-inch thick inset steel door that weighs 140 pounds just by itself. The hinge side is backed by a very heavy flange that protects the vault against attacks where the hinges might be cut away. Because of the flange, that would be a huge waste of time for burglars. The basic unit (twin bed size) weighs about 650 pounds. The vault's pair of cylinder locks are a robust "bump proof" and relatively pick-proof lock variety with cylinders and keys that are made in Israel. These vaults have a two-hour house fire protection rating. At around $2,000, they are relatively expensive per cubic foot, compared to traditional upright gun safes. So I would mostly recommend them to families where space is at a premium. One of the vaults that I examined was a double vault where the two Bed Bunkers are bolted to a welded spacer, providing a platform for a king-size bed. The combined empty weight is 1,450 pounds, so it would be exceedingly difficult for burglars to tote that vault away.

The legs on these vaults have threaded attachments, with a very long adjustable length of travel. They can be screwed all the way in so that the vault nearly touches the floor. Or they can be completely removed, allowing you to bolt the vault to the floor, with lag bolts. For the greatest security, I recommend bolting your safe down. By attaching a long dust ruffle, you can make a Bed Bunker disappear from view. (Use a 14-inch dust ruffle if you don't use the vault legs.)

As with any other home security purchase, be sure to keep quiet about it. Do not mention to friends or relatives that you've bought a vault, and swear your kids to secrecy. Just remind them that if they blab about it, then a possible consequence is that burglars will steal a portion of their eventual inheritance. When burglars learn of a lucrative yet hard target, they'll probably come equipped with a cutting torch that can defeat even the best gun vault. So remember: Loose lips sink ships!

Lastly, be careful about where you leave your vault keys. Don't just put a vault key on your key ring. It is best to establish a well-hidden yet quickly-accessible place to store your vault keys. A fake electrical outlet box is one well-proven ruse. (Unless you live off grid, every room in your house probably has several outlets, so an extra one won't be noticed by all but the most sophisticated burglars.) Another good hiding place is a fake can of shave cream in the bathroom drawer.

I often have blog readers and consulting clients send me questions about firearms calibers. They are often confused, but this not always their fault. It is a confusing, complex, and often arcane topic. A lot of the facts that you will find are mere trivia, but since safety is an issue--(we mustn't fire the incorrect ammo in our guns!)--it is important to study.

To begin: Metric caliber designations are usually written with an "x" in the middle to distinguish the bore diameter and case length. For example, the 6.5x55 designation tells us that the cartridge uses a 6.5 mm bullet, and a case that is 55 mm in length.

The following table is partly Creative Commons licensed (courtesy of Wikipedia), with additions by JWR (such as 7.5mm, 7.7mm, .375 H&H, .455 and .577) and minor corrections and comments. Hence, I am retaining my moral rights.

As you can see, there are some amazing inconsistencies in cartridge designations. (See, for example, .405 Winchester and .38-40.) As Jim Keenan at the Firing Line Forums aptly put it: "It is usually best to just accept cartridge names; trying to figure out reasons for the names leads to insanity.")

One regular source of confusion in cartridge naming is whether "bore diameter" refers to the rifling land dimension versus rifling groove dimension. For example, most .303 British rifles have a land-to-land diameter of .303 and a groove-to-groove diameter of .311. So when you handload a ".303" cartridge, you actually use a .311 diameter bullet.

Specifications have also changed for a few types of ammunition. One example is the 8mm Mauser cartridge. Early production 8x57 rifles used 8.08 mm (.318 caliber) bullets, but the later guns used 8.2 mm (.323 caliber) bullets.

Now, on to the realm of shotguns, where life is simpler but there is still some minor confusion.

10 Gauge .775 19.69mm 10 Revived popularity, due to the mandate of lead-free shot for waterfowl hunting in the U.S.

Note that there are presently enormous revolvers being marketed that can fire both .45 Colt cartridges and .410 shotshells. (The Taurus "Judge" series.) I attribute the popularity of these revolvers to: A.) Ignorance of ballistics, and B). The unerring willingness of the American people to spend their money on impractical toys.

Mr. Rawles,

While I agree, of course, with Steve V.'s assertion that firearms need to be handled safely, people should be familiar with their firearms, and training is a good thing; I very much disagree with the assertion that operating the slide of an automatic pistol the correct way is "an extremely bad habit".

First, his complaints about what happens when racking a slide with thumbs on opposite sides of the slide and facing opposite directions aren't very valid in my opinion. The notion that a shooter's hand and arm conceal the pistol making it "hard to see exactly where the muzzle is pointing" is silly. Even with a small-frame Glock 26 or 27 I can still see the muzzle when operating the slide. But I don't have to even see the muzzle to know where it is pointing because the hand on the pistol grip is indexed and I know where my fingers point without having to actually see them. Almost any man, woman, or child can stretch out their arm and point their index finger and know where their arm and finger are pointing without looking at them.

Also, at no time does the muzzle point "along or into the left lower forearm". Even if I had forearms like Popeye, this would not happen. The pistol is pointed downrange, the left hand is on the slide, well behind the muzzle, and every other part of the left arm is farther back than the hand.

Second, I manipulate a pistol up high in my field of view so that I can see the pistol, the environment, and potential adversaries all at once. Manipulating the slide the way that Steve prefers when the pistol is up high in the shooter's field of view is nearly impossible (which is why he recommends the low 45-degree position). You have to either turn the right wrist to the right (for a right-hand shooter) in order to effectively grasp the slide with the off hand or you have to contort your arms to bring your forearms parallel with each other with the elbows nearly together in order to keep the pistol pointed ahead and get your off hand onto the slide with the thumb-forward grip that was recommended.

If you do see someone pointing a pistol to their left or right while manipulating the slide -- regardless of their approach to manipulating the slide -- it is a training issue and should no doubt be corrected. But that doesn't mean that a mechanically inefficient or awkward approach that is better only for the range should be preferred. - Jeff in Georgia

 

Mr. Rawles,
The article by Steve V. leaves me with some concerns for the general populace.  I have spent my entire adult life in public service, serving both my country (13 years) and my state (13+ years), always carrying a weapon. 

My concerns are the way Steve V. has individuals pulling the slide to the rear; “With the left hand, reach over the slide (your thumbs should now both be pointing in the same direction – forward, but on opposite sides of the weapon), and with thumb and forefinger grasp the slide near the muzzle. Pull the slide back and lock it open.”  This does multiple things wrong in my book.  One, it places your hand operating the slide close to the muzzle.  No plan survives first contact!  With a sympathetic response, one could be missing a finger and thumb or parts thereof.  Second, you only have one finger and only a portion of your thumb on the slide to obtain your grip.  Third, you are potentially placing your body, dripping blood, or clothing over the ejection port and possibly in the chamber.  And fourth, this only allows you to hold the weapon vertical, as in a firing position or cant it to the left; both ways again cause possible problems and more malfunctions if your intent is to clear a malfunction.

Steve V. states that “most people rack the slide by holding the pistol in the right hand, grasping the rear of the slide with the other hand in a manner such that the thumbs are pointing in opposite directions on the same side of the weapon,” is an extremely bad habit.  I completely disagree and argue the following reasons.  One, your hand operating the slide is nowhere near the muzzle and is rear of the ejection port, clearing it of any self-induced malfunctions or injuries.  Two, you have four fingers on the right and most of your palm on the left of the slide making a C clamp.  Blood is slippery and the more friction area you have between you and the slide the better.  Three, this forces you to either have the weapon upright or allows you to cant the weapon to the right allowing anything you don’t want, i.e. a spent casing, to fall free.  Obviously to the right is preferred.

Muzzle Discipline.  This is a taught technique or an allowed bad habit from the start.  Weapons are always down range or pointed downward (cover/ready position) with the finger off the trigger until necessary.  Even when clearing a malfunction, loading, unloading, or reloading, the muzzle faces the enemy.  It is muscle memory and if taught from the start is second nature.  All should be taught never to flag (point, cross, etc.) your buddy with the muzzle, always keeping in mind weapons are inherently dangerous.  That said, good guys walk in front of other good guys in the heat of the moment.  Your finger should be off the trigger and if you are up on target, lower [your muzzle to a] ready [position] if this happens.  After they pass, move if necessary, and re-acquire/re-engage your target.

Final thought when clearing your weapon.  One, drop the magazine allowing it to hit the ground or floor!  No need to train a bad habit by grabbing it as it drops.  If you do, you have the potential of grabbing an empty in combat.  Let it drop!  Two, rack the slide three times to the rear, locking the slide to the rear on the third time.  If you do it three times, you shouldn’t be tempted to try and catch that round as it comes out, yet again another bad habit.  After locking the slide to the rear, visually inspect the chamber and the magazine well for anything. 

Practice doesn’t make perfect.  Perfect practice makes perfect!
Stay safe and when in doubt, empty a magazine!  Or two. Regards, - T.F.

Sir,
What advice could you give for moving one's store of firearms and ammo a considerable distance in a relocation within the continental Unites States?  I am in one of the reasonably free northern New England states and figure that if I can make it through New York state without being stopped I can breathe a relative sigh of relief.  Still, I envision a scenario where the vehicle with the supplies is never left unattended.  And if I had to make this move alone I would consider doing so in a motor home so that I would only have to stop for gas.  Shipping would be legal, but risky just the same, not to mention costly.  Your thoughts on this matter would be appreciated. Thank You, - Scott S.

JWR Replies: You are correct that commercial movers cannot be trusted with firearms or ammunition. Don't make the mistake of thinking that you can hide them in the bottom of a box that is marked "Packed By Owner" ("PBO"). They will very likely get pilfered. A good friend of mine lost a nice Series-70 Colt Model 1911 pistol that way. The moving company's response when he tried to file a claim was that they would only reimburse him a pittance at their standard rate for "three pounds of household goods." Not only is the temptation for theft too great for the individual employees, but companies often have liability restrictions. For example, most moving firms refuse to transport ammunition because they mistakenly consider it a fire hazard.

My advice is to rent a fully-enclosed U-Haul type truck with a roll-up door. Buy a top quality round padlock to secure the rear door. If your drive is lengthy so that you must make an overnight stay, then pick a motel where your room is on the ground floor, and where the truck will be within line-of-sight to your motel room window. The very best situation would be to back the truck in, so that the cargo door is directly outside your motel room, just a few feet from your window. (This, however, is rarely possible if you are driving a big truck.)

You can legally use a common carrier such as UPS or FedEx to ship a gun "from yourself to yourself", without having to do a transfer through a Federal Firearms license holder. This might be practicable if you need to move just a couple of guns. Or if you are doing a cross-country move and either flying or traveling by train while your household goods are simultaneously shipped via truck, then you can check your firearms with your baggage, in a locking airline-approved case. I recommend Pelican brand and Starlight brand cases that have large locking flanges for padlocks. Make sure that you put padlocks at both ends of the case, so that it cannot be pried open.

Dear JWR:
Regarding the recent Cold Weather Patrol Tactics and Techniques article, just one note about condensation prevention from bringing a cold weapon indoors. Packing or leaving a heavy duty garbage or similar bag outside and placing your weapon inside the bag can greatly reduce condensation from the indoor climate. Just place your weapon completely inside the bag. I like to compress the opening in my hand like a balloon opening and instead of blowing into this opening, I suck as much air out as I can with my lungs. If two or more deep inhalations are required to remove excess air after manual compression of the bag, remember to close your hand around the bag opening to avoid the bag expanding. Once you are satisfied you have removed as much air as possible, tie the opening very tightly with a rubber band, tape or the bag itself. I have found this technique to nearly eliminate all condensation on the weapon as the metal warms to ambient indoor temperature, but the plastic bag will have some moisture on the outside.

I do not recommend the usage of heavy duty compression or vacuum bags if the weapon is your first line defense arm. Unless these bags have a rapid way to open and extract your weapon, I prefer the tear-away and cheap garbage bags to allow rapid rearming when needed. However, as an aide to the air removal, I have seen the usage of small hand pumps and even a small battery powered air mattress inflator used in a reverse role. - J.G.

JWR Replies: That is a good suggestion. Of course, once a gun fully equalizes to room temperature, it should soon be removed from the bag, so that any trace of moisture doesn't settle on the gun an induce rust.
