In years past, the U.S. Army Marksmanship Unit published weekly reloading “how-to” article on the USAMU Facebook page. Here is a very informative USAMU article the subject of case lubrication. Tasked with producing thousands of rounds of ammo for team members, the USAMU’s reloading staff has developed very efficient procedures for lubricating large quantities of cases. This article reveals the USAMU’s clever “big-batch” lube methods. For other helpful hand-loading tips, visit the USAMU Facebook page on upcoming Wednesdays.
Rapid, High-Volume Case Lubrication
Today’s topic covers methods for quickly applying spray lube to cartridge cases prior to sizing. A typical order for this shop may be 25,000 rounds, so [speeding up] the lubrication process can be a real time-saver. While your ammunition lots probably aren’t this large, the efficient methods discussed here may help save a considerable amount of time over your handloading career. Our case lubrication rates range from 1500-1600 cases per hour, to 2400-2500 cases per hour, depending on caliber.
This shop uses virgin brass, whereas most home handloaders use fired brass, which necessitates some small changes at times. These will be discussed as they arise. Begin with fired brass that has been tumbled clean.
Ensure as much tumbling media as possible is removed from the brass, as when it gets into a size die, it can dent cases significantly. This is a good time to round out dents in the case mouths using a tapered tool to prevent damage from the decapping stem.
First, dump the clean cases into a large box or reloading bin. Shake the bin back and forth so that many cases are oriented with the mouths up. Next, pick up as many cases as is convenient with the mouths “up”, from natural clusters of correctly-oriented cases. With 7.62mm-size cases, this is usually 3-4, and with 5.56mm cases, this can be up to 8-10. Place the cases into the rack slots, mouth-up. Doing this in groups rather than singly saves considerable time. Once these clusters have been depleted, it will be time to re-shake the bin to orient more cases “up.”.
This photo shows a case lubrication rack made by a USAMU staffer.
Naturally, adjust the spacing to best fit the calibers you reload. We have found this size … convenient for handling through the various phases of case lubrication/transfer to progressive case feeders for processing. Note that the 1/2-inch angle does not cover much of the critical case area at the base, just forward of the extractor groove, where most re-sizing force will be exerted. As the USAMU uses virgin brass, less lubrication is required for our brass than would be needed for Full Length (FL) sizing of previously-fired brass.
NOTE: The amount applied using our rack is easily enough for our purpose. If using fired brass, be sure to adequately lube this base area to avoid having cases stick in the full-length sizing die.
Using a spray lube, coat the cases adequately, but not excessively, from all sides. Be sure to get some lube into the case mouths/necks, in order to reduce expander ball drag and case stretching/headspace changes. The spray lube this shop uses does not harm primers or powder, and does not require tumbling to remove after lubing.*
Take a close look at the photo above. The USAMU shop uses a common kitchen turntable, which allows the rack to be rotated easily. We place this in a custom-made box which prevents over-spray on to floors and walls.
Angled Box Method for Smaller Cases to be Neck-Sized
A refinement of the above method which especially speeds processing of 5.56x45mm cases is as follows. A small cardboard box which holds about 100 cases is fitted with an angled “floor” secured by tape. With the smaller 5.56mm cases, usually about 8-10 cases per handful can be picked up, already correctly-oriented, and placed into the box together. This prevents having to place them into the rack slots, saving time.
HOWEVER, note that this does not allow nearly as much lube access to the case bodies as does the rack. For our purposes — neck-sizing and setting neck tension on new brass, this works well. If using this procedure with fired brass, take steps to ensure adequate lube to prevent stuck cases.
As always, we hope this will help our fellow handloaders. Good luck, and good shooting!
*A two-part test performed here involved spraying primed cases heavily, while getting more lube into the case mouth/body than even a careless handloader would likely apply. The second part of the test involved literally spraying considerable quantities of the lube directly into the cases, drenching the primers. After a several-day wait to allow the lube to penetrate the primers, they were then fired in a test barrel. All fired normally; no unusual reports were noted. This bolstered confidence that normal amounts of the lube would not adversely affect our ammunition, and we have been pleased with the results over several years.

On Wednesdays, the U.S. Army Marksmanship Unit often publishes a reloading “how-to” article on the USAMU Facebook page. One “Handloading Hump Day” post covered bore-cleaning, specifically the use of pull-through style bore-snakes. Visit the USAMU Facebook page each Wednesday for other helpful tips.
Today, we’ll shift from handloading to rifle bore cleaning and maintenance, with information courtesy of the USAMU’s Custom Firearms Shop. We recently had some inquiries about bore cleaning, and this seems a good opportunity to share. After all, even the best handloads won’t yield their full potential in a poorly-cleaned and maintained rifle.
NOTE: Hoppes claims a trademark on the term “BoreSnake” (one word, no hyphen). For this article, the USAMU has used the term in hyphenated form, two words. We believe the USAMU is referring to a Hoppes Brand Boresnake, not a different bore cleaning rope.
BORE-SNAKES: MIRACLE REPLACEMENT FOR THE CLEANING ROD?
The experiences of both our firearms test specialist and this writer have given no evidence that proper use of a clean bore-snake will damage a match barrel. Of course, one does not pull the bore-snake at an angle to the crown when removing it — pull it straight out, parallel to the bore’s direction, to prevent crown wear over time.
Bore-snakes are very useful for some applications (primarily a hasty, interim wipe-down). In [my] experience they cannot replace a thorough cleaning with a proper rod and brushes. While the experiment cited here involves rimfire, it may help illustrate. Several years ago, the writer used his new, personal Anschutz to investigate the bore-snake issue. It had been fired ~350 rds with match ammo and had had 3 typical rod/brush cleanings.
Next, starting with a clean bore, the writer fired 300 more rounds without cleaning in order to build up a “worst-case” fouling condition. Afterwards, the writer examined the bore with a Hawkeye bore scope. There was a uniform, grey film down the entire barrel, with some small, intermittent lead build-up at and just forward of the throat.
Some bore-cleaning rope products feature separate, detachable bronze brush and bore mop segments. This allows more usage options (e.g. mop only), and makes it easier to clean the brush elements:
A new bore-snake was then wet with solvent and pulled through the bore. The Hawkeye revealed that the grey fouling was gone, and much of the visible fouling at the throat was reduced. However, nine more passes with the bore-snake, checking after each with the Hawkeye, revealed no further improvement in cleaning. The writer then cleaned with two wet patches, observed, then one stroke of a new, wet bronze brush, and one wet patch to clean out residue.
The Hawkeye showed a significant reduction in fouling at the throat; it was virtually gone. A second pass with a wet bronze brush and a wet patch removed the remaining fouling. Scrubbing the bore further, checking to see how much fouling was removed, revealed no significant improvement. The reason for this test was to learn what’s needed to get (and keep) this Anschutz clean with minimal cleaning rod use — and thus, minimal risk of bore damage/wear. Leaving fouling in the bore promotes corrosion over time.
Obviously, this applies to a nice, smooth rimfire match barrel, using good, well lubed ammo. It doesn’t apply directly to the use of copper-jacketed bullets, which leave a stubborn fouling all their own. However, it does suggest that while the bore-snake can be helpful and a useful field-expedient, to truly clean a rifle barrel one will still need a good quality rod, bronze brush and solvents. [Editor: Add a good-fitting cleaning rod bore guide.]
SO, WHAT ABOUT BORE SNAKES FOR BARREL BREAK-IN?
The goal of barrel break-in is to fire each shot through a clean barrel, preventing copper buildup and allowing the bullets their best chance at burnishing sharp edges. Thus, it seems this purpose would be best served by one’s usual rods, brushes and rod guides.

The U.S. Army Marksmanship Unit (USAMU) has published a great series of reloading “how-to” articles on its Facebook Page. This post covers key factors to consider when loading ammunition for Match Rifles and Service Rifles, with a particular focus on self-loading “gas guns”. Visit the USAMU Facebook Page regularly for other, helpful reloading and marksmanship tips.
We offer some “cardinal rules” to help new gas-gun handloaders with safety and efficiency. These address both Match Rifle and Service Rifle versions of the AR15, M1 Garand, M1A, and M110. However, they can also improve safe reloading for many other auto-loaders such as M1 Carbines, FALs, SIGs, etc. The author distilled these principles many years ago to help focus on the essential aspects of these rifles.
RULE ONE: Service Rifles Are Not Benchrest Rifles
Gas-guns require a relatively loose fit between ammunition and chamber (vs. bolt actions) for safe, smooth operation. Many techniques, such as neck sizing and keeping cartridge headspace quite tight, are popular in the extreme bolt gun accuracy realm. However, they are of little value with Service Rifles, and some could even be hazardous. Before adopting a specialized technique, seriously consider whether it is appropriate and beneficial in a gas-gun.
RULE TWO: Never Compromise Safety to Obtain Accuracy
Example: If choosing a brand of great, but ultra-sensitive match primers offers possibly better accuracy at the risk of slam-fires in your design of rifle, don’t do it! You are issued exactly two eyes and ten fingers (best-case scenario). Risking them trying to squeeze 0.25 MOA better accuracy out of an M1A, etc. simply isn’t worth it.
RULE THREE: Tailor the Precision to Your Individual Skill and Your Rifle’s Potential
This has been addressed here before, but bears repeating for newcomers. If you are struggling to break out of the Marksman Class, or using a CMP M1 “As-Issued,” then laboriously turning the necks of your 600-yard brass is a waste of time. Your scores will improve much faster by practicing or dry-firing. On the other hand, if the reigning champions anxiously check your scores each time you fire an event, a little neck-turning might not be so far-fetched.
Verifying Load Improvements — Accuracy hand-loading involves a wide variety of techniques, ranging from basic to rather precise. Carefully select those which offer a good return on investment for your time and labor. In doubt? Do a classic pilot study. Prepare ammo for at least three or four ten-shot groups with your new technique, vs. the same with your standard ammo. Then, pick a calm day and test the ammo as carefully as possible at its full distance (e.g. 200, 300, or 600 yards) to verify a significant improvement. A little testing can save much labor!
This video explains the procedure for ordering an M1 Garand from the CMP.
RULE FOUR: Be Your Own Efficiency Expert
Serious Service Rifle shooters generally think of ammunition in terms of thousands of rounds, not “boxes”, or even “hundreds”. Analyze, and WRITE DOWN each step in your reloading process. Count the number of times each case is handled. Then, see if any operations can be dropped or changed without reducing safety or accuracy. Eliminating just two operations saves 2000 steps per 1000 rounds loaded. Conversely, carefully consider any measurable benefits before adding a step to your routine.
RULE FIVE: In Searching for Greater Accuracy with Efficiency, Look for System Changes
For example, instead of marking your 300-yard rounds individually to differentiate them from your 200-yard ammo, would a simple change in primers work? If accuracy is maintained, using brass-colored primers for 200 and silver for 300 provides an indelible indicator and eliminates a step! Similarly, rather than spending hours selecting GI surplus brass for weight and neck uniformity, consider splurging on some known, high-quality imported match brass for your 600-yard loads. Results should be excellent, time is saved, and given limited shooting at 600 yards, brass life should be long.
RULE SIX: Check All Your Primers Before Packaging Your Loaded Ammo
This seems simple and even intuitive. However, many slam-fires (which were much more common when M1s and M1As were the standard) are due, at least in part, to “high” primers. Primers should be seated below flush with the case head. The USAMU has addressed this at length in a previous column, but each round should be checked for properly-seated primers before they are packaged for use.

In the archives of The First Shot (the CMP’s Online Magazine), SGT Walter E. Craig of the USAMU discusses physical conditioning for competitive shooters, particularly High Power competitors. Fitness training is an important subject that, curiously, is rarely featured in the shooting sports media. We seem to focus on hardware, or esoteric details of cartridge reloading. Yet physical fitness also matters, particularly for High Power shooters. In his article, Craig advocates: 1) weight training to strengthen the Skeletal Muscle System; 2) exercises to build endurance and stamina; and 3) cardiovascular conditioning programs to allow the shooter to remain relaxed with a controlled heart beat.
SGT Craig explains: “An individual would not enter a long distance race without first spending many hours conditioning his/her body. One should apply the same conditioning philosophy to [shooting]. Physical conditioning to improve shooting skills will result in better shooting performance[.] The objective of an individual physical training program is to condition the muscles, heart, and lungs thereby increasing the shooter’s capability of controlling the body and rifle for sustained periods.”
In addition to weight training and cardio workouts (which can be done in a gym), SGT Craig advocates “some kind of holding drill… to develop the muscles necessary for holding a rifle for extended periods.”
For those with range access, Craig recommends a blind standing exercise: “This exercise consists of dry-firing one round, then live-firing one round, at a 200-yard standard SR target. For those who have access only to a 100-yard range, reduced targets will work as well. Begin the exercise with a timer set for 50 minutes. Dry-fire one round, then fire one live round and without looking at the actual impact, plot a call in a data book. Continue the dry fire/live fire sequence for 20 rounds, plotting after each round. After firing is complete, compare the data book to the target. If your zero and position are solid, the plots should resemble the target. As the training days add up and your zero is refined, the groups will shrink and move to the center.”
Fitness training and holding drills help position shooters reach their full potential. Here is 6-Time U.S. National Long Range Champion John Whidden.
Training for Older Shooters
Tom Alves has written an excellent article A Suggested Training Approach for Older Shooters. This article discusses appropriate low-impact training methods for older shooters. Tom explains: “Many of the articles you will read in books about position shooting and the one mentioned above are directed more toward the younger generation of shooters in their 20s. If you look down the line at a typical high power match these days you are likely to see quite a few folks who are in their middle 30s and up. Many people in that age range have had broken bones and wear and tear on their joints so a training program needs to take that into account. For instance, while jogging for an extended period for heart and lung conditioning may be the recommended approach for younger folks, it may be totally inappropriate for older people.”
The Action Target Sport Plate Rack is specifically designed for .22 LR Rimfire shooting. This rack features six 4″-diameter plates that reset with a provided cable.
Shooting plates is fun. You get immediate feedback — “instant gratification” when you make a hit. When shooting steel inside 100 yards, we like to use .22 LR rimfire guns. The ammo is inexpensive, noise levels are lower (though you still need ear protection), and at close ranges there are fewer issue with ricochets and bullet splash-back. Additionally, for busy folks who don’t have time to reload, you can pick up a .22 LR rifle or pistol, grab a couple $5 boxes of ammo, and get to the range in a few minutes. The convenience means it is easier to shoot every week if you like.
SFC Joel Turner from the USAMU’s Action Shooting Team offers a few pointers on how to shoot plates quickly and accurately. He’s using a centerfire pistol, but the same principles apply for rimfire handguns. Click speaker icon to activate audio.
New .22 LR CP33 Pistol is Great for Plates
If you like shooting plates, one of the better new handguns for the job is Kel-Tec’s CP33. We tested this interesting handgun at the 2019 SHOT Show Media Day at the Range, and were impressed. The pistol is big, but balances well. The sights are easy to see, and the full-length rail lets you easily mount a variety of optics. The trigger is surprisingly good — better than 90% of rimfire handguns out there. For the plates game, this “quad-stack” gun can handle long stages without mag changes. The standard clear-sided CP33 magazine holds 33 rounds of .22 LR ammo.
If you are interested in an affordable, but very accurate, high-capacity semi-auto rimfire pistol you should consider Kel-Tec’s new CP33. Shooting Sports USA (SSUSA) notes: “The rapid growth of rimfire competition in Steel Challenge has prompted some gun makers to enter the fray. Kel-Tec is one, and their new CP33 .22 LR pistol has a lot of potential.” Popular YouTube host 22 Plinkster tested the gun and reports: “This handgun has been 100% reliable IF I load the magazine the right way… and it’s pretty dog-gone accurate.” The video below shows the best way to load the 33-round magazine:
SSUSA’s testers tried the pistol with a variety of ammo and it consistently shot about one-half-inch for five shots “from a 25-yard sandbag bench rest using the iron sights.” SSUSA noted that the gun disassembles quickly and easily by removing one central pin. That’s a nice feature.
Overall SSUSA’s tester, Chris Christian, was impressed with the gun, saying it balanced well and the sights aligned naturally: “…the neutral-balance-point grip produced an almost instinctive sight alignment.”
Christian used the CP33 in a 6-stage Steel Challenge Match, and did well: “I decided to shoot Rimfire Pistol Iron (RFPI) and used the CCI Mini-Mag. The high-speed ammo ran perfectly. [T]he bright sights and handling qualities let me finish top among iron-sight shooters and even hold my own with C and B class rimfire pistol shooters using optical sights. It would be interesting to put a reflex sight on the gun, and maybe even shoot some Bullseye with it.”
The competition was founded in 1981 by Mike Dalton and Mike Fichman, in Southern California. The two Mikes wanted an exciting alternative to paper targets and came up with the all-steel format. The Steel Challenge World Speed Shooting Championships have grown to one of the largest professional pistol competitions in America. In 2018, hundredes of competitors from the United States and around the world competed at the Talladega Marksmanship Park for glory and huge cash prizes.
The Steel Challenge is governed by the Steel Challenge Shooting Association (SCSA) that consists of eight standardized stages with three types of steel targets: small circle, big circle, and square. Here is a steel challenge layout in Germany.
Steel Challenge is similar to IPSC, but has simpler rules and more consistent stage designs. Up until 2011 the annual Steel Challenge World Championship was held in Piru, California every year. Then, renamed the World Speed Shooting Championships (WSSC), the Championship was held in Frostproof, Florida (2012, 2013), St. George, Utah (2014), San Luis Obispo, California (2015-2017), and Talladega, Alabama (2018-2022). There are also over 100 Steel Challenge Regional Matches held around the country.

Emil Praslick III is widely recognized as one of the greatest wind wizards on the planet — a master at identifying wind value and direction, and predicting wind cycles. As coach of the USAMU and top civilian teams, Emil has helped win many high-level championships. In the three videos we feature today, Emil, who works with Capstone Precision Group (Berger, Lapua, SK, Vihtavuori) and Team Applied Ballistics, explains how to determine wind direction and velocity using a variety of indicators. Praslick, now retired from the U.S. Army, was an 18-time National and 2-time World Champion coach with the USAMU.
Video ONE: Wind Theory Basics — Understanding “Wind Values”
In this video from UltimateReloader.com, Emil explains the basics of modern wind theory. To properly understand the effect of the wind you need to know both the velocity of the wind and its angle. The combination of those variables translates to the wind value. Emil also explains that the wind value may not be constant — it can cycle both in speed and velocity. Emil also explains some of the environmental conditions such as mirage that can reveal wind conditions.
Video TWO: Determining the Direction of the Wind
Key Point in Video — Find the Boil
Emil explains how to determine wind direction using optic. The method is to use spotting scope, riflescope, or binoculars to look for the “Boil” — the condition in mirage when the light waves rising straight up. The wind will generate that straight-up, vertical boil in your optics when it is blowing directly at you, or directly from your rear. To identify this, traverse your scope or optics until you see the boil running straight up. When you see that vertical boil, the direction your optic is pointing is aligned with the wind flow (either blowing towards you or from directly behind you).
Video THREE: The No Wind Zero Setting
In this second video, Emil defines the “No-Wind Zero”, and explains why competitive shooters must understand the no-wind zero and have their sights or optics set for a no-wind zero starting point before heading to a match. In order to hit your target, after determining wind speed and direction, says Emil, “you have to have your scope setting dialed to ‘no wind zero’ first.”
Coach of Champions — Emil Praslick III
SFC Emil Praslick III, (U.S. Army, retired) works with Berger Bullets and Applied Ballistics. Emil served as the Head Coach of the U.S. National Long Range Rifle Team and Head Coach of the USAMU for several years. Teams coached by Emil have won 33 Inter-Service Rifle Championships. On top of that, teams he coached set 18 National records and 2 World Records. Overall, in the role of coach, Praslick can be credited with the most team wins of any coach in U.S. Military history.

The U.S. Army Marksmanship Unit regularly publishes technical articles on the USAMU Facebook page. One informative USAMU article covered mechanical issues and related ignition irregularities that can cause vertical fliers even with good ammunition in an otherwise excellent rifle. We highly recommend you read this article, which offers some important tech tips.
Vertical Dispersion: Mechanical/Ignition Issues?
Poor or inconsistent ignition has long been known to be one of the “usual suspects” when one encounters vertical fliers that just shouldn’t be there. By having a sense of some of the basic principles involved, and a few basic areas to check, the shooter may avoid colsiderable frustration, not to mention time, expensive loading components and barrel wear.
Is your well-built rifle of high-quality components plagued with vertical fliers across more than 1-3 handload combinations? Consider the bedding, crown and scope/sight mounts. Are they correct? If so, then you might check for ignition issues before boldly undertaking an extensive, expensive, and quite possibly fruitless quest for the “magic handload”.
SEEING IS BELIEVING: While the author had been aware for many years that poor ignition should be considered and ruled out when dealing with vertical fliers in an otherwise-excellent rifle, actually seeing the problem and its almost instantaneous cure really drove the lesson home.
He was working with a “dot” rifle – a .22 LR match rifle that really stacked bullets into little piles at 50 yards and beyond. With one lot of ELEY Tenex, it produced consistent “bughole” groups at 50, but with another, selected lot of Tenex, similar groups were regularly ruined by single, vertical fliers that did not appear in other rifles. Rather than spending days burning up expensive, select ammunition looking for “magic lots”, he contacted a well-respected rimfire gunsmith and explained the situation.
Without so much as batting an eye, the highly-experienced ‘smith tore into the rifle’s action, and quickly found the cause(s) of the problem. He discovered a demonstrably weak firing pin spring, plus a chip out of the face of the firing pin where it contacted the cartridge rim.
After replacing and tuning the offending parts, the rifle immediately began shooting tiny, bughole groups with the previously “unacceptable” lot of Tenex. Centerfire rifles can also benefit from ensuring positive, consistent ignition. A wise riflesmith is literally worth his weight in gold!
So, what are some issues we as shooters can inspect in our rifles to help determine if ignition woes could be part of our problem? At the club level, ask yourself if that “experienced” Remington, Winchester 70, or even Springfield-based match bolt gun you’re using is still running its’ original 40-80 year-old factory striker spring? If so, a new replacement is cheap insurance against current or future problems. (And BTW, it might be best to stick to the normal, factory-spec spring weight. A super-powerful spring can cause vertical, just as a weak one one can.) Along with that, a routine check for proper firing-pin protrusion is a quick preventive measure that can rule out potential issues.
Other areas to consider are the centering and consistency of the firing pin’s operation in the bolt. Admittedly, with the increasing use of precision-machined custom actions, this is becoming less an issue every day. Below is the firing pin assembly from a custom BAT action:
However, particularly with factory actions, a very quick and easy check is to remove the bolt, let the firing pin go forward, and look at the firing pin tip through the firing pin hole. Is the tip off-center in the hole, and possibly striking it as it moves forward? Is the hole out-of-round or burred from being struck repeatedly? If so, a trip to the riflesmith is likely in order.
Similarly, machining issues in the bolt/firing pin system can lead to rough and erratic firing pin movement, in which the firing pin drags against an internal surface of the bolt. In high-quality rifles these issues are relatively rare, but not unheard-of, and it takes mere minutes to rule them out. It may be worthwhile to remove the cocking piece/firing pin/spring assembly and look for any unusual gouges, dings, peening, burrs or signs of abnormal wear.
This task is especially easy with Winchester 70s, Springfields, and the similar Mauser 98s, involving little more than the push of a button and unscrewing the cocking piece assembly. This is just one of the many reasons these tried-and-true actions have earned such a loyal following in the field, among hunters who must maintain their rifles away from a shop.
Particularly with older rifles, watch for and remove excess grease (or even Cosmoline!) from both the firing pin assembly and inside the bolt. This can help improve firing pin speed and consistency. Other bolt-action designs may need a take-down tool or other measures.
As part of this inspection, AFTER ENSURING THE RIFLE IS UNLOADED, slowly cock the rifle, dry-fire, and repeat several times. Listen carefully near the action for inconsistency in the sounds it generates. Does the striker falling make the same sound each time? Do you hear or feel grinding upon operation? If so, where?
Be sure to check the operation of the cocking piece (bolt shroud), firing pin within the bolt shroud, the cocking piece cam and the rear of the bolt body where the cocking piece cam operates. As with our examination for abnormal wear marks discussed above, look for marks indicating roughness or a possible need for light polishing. Then, clean and lightly grease the bearing surfaces while you’re at it.
Remington 700 bolt shroud and cocking cam
These are relatively easy checks that shooters can undertake to perform a preliminary inspection on their own. Other mechanical issues can also cause ignition issues, chiefly centered around the action of the trigger, sear and sear spring. If these are suspected, a trip to an experienced, qualified riflesmith for diagnosis is recommended. We hope you find this information helpful! Join us again next week, and in the meantime, enjoy the shooting sports safely!

The U.S. Army Marksmanship Unit regularly published a reloading “how-to” article on the USAMU Facebook page. One excellent “Handloading Hump Day” post covered preparation of once-fired 5.56x45mm brass. This article, the first in a 3-part series, has many useful tips. If you shoot a rifle chambered in .223 Rem or 5.56x45mm, this article is worth reading. You can obtain once-fired Lake City 5.56x45mm brass for less than half the cost of premium .223 Rem brass.
This week, Handloading Hump-Day will answer a special request from several competitive shooters who asked about procedures for morphing once-fired GI 5.56mm brass into accurate match brass for NRA High Power Rifle use. The USAMU has used virgin Lake City (LC) 5.56 brass to win National Championships and set National Records for many years. In this 3-part series, we’ll share techniques proven to wring match-winning accuracy from combat-grade brass.
GI brass has an excellent attribute, worth noting — it is virtually indestructible. Due to its NATO-spec hardness, the primer pockets last much longer than most commercial brass when using loads at appropriate pressures.
Preparing Once-Fired GI 5.56 Brass for Reloading (Part 1 of 3)
Assuming our readers will be getting brass once-fired as received from surplus dealers, the following steps can help process the low-cost raw material into reliably accurate components.
1. Clean the Brass
First, clean the brass of any dirt/mud/debris, if applicable. Depending on the brass’s condition, washing it in a soap solution followed by a thorough rinsing may help. [This step also extends the life of the tumbling media.] Approaches range from low-tech, using gallon jugs 1/2 full of water/dish soap plus brass and shaking vigorously, to more high-tech, expensive and time-consuming methods.
2. Wet-Tumbling Options (Be Sure to Dry the Brass)
When applying the final cleaning/polish, some use tumblers with liquid cleaning media and stainless steel pins for a brilliant shine inside and out, while others take the traditional vibratory tumbler/ground media approach. Degree of case shine is purely personal preference, but the key issue is simple cleanliness to avoid scratching ones’ dies.
If a liquid cleaner is used, be SURE to dry the cases thoroughly to preclude corrosion inside. One method is to dump the wet brass into an old pillow case, then tilt it left/right so the cases re-orient themselves while shifting from corner to corner. Several repetitions, pausing at each corner until water stops draining, will remove most water. They can then be left to air-dry on a towel, or can be dried in a warm (150° F-200° F max) oven for a few minutes to speed evaporation.
Shown below are Lake City cases after cleaning with Stainless Media (STM). Note: STM Case cleaning was done by a third party, not the USAMU, which does not endorse any particular cleaning method.
NOTE: The USAMU Handloading (HL) Shop does not RE-load fired 5.56 brass. We use virgin LC brass with our chosen primer already staked in place. However, our staff has extensive personal experience reloading GI brass for competition, which will supplement the Shop’s customary steps. In handloading, as in life, there are many ways to accomplish any given task. Our suggestions are note presented as the “only way,” by any means. Time for loading/practicing is always at a premium. Readers who have more efficient, alternative methods that maintain top accuracy are invited to share them here.
3. Inspect Every Case
Once dry, inspect each case for significant deformation (i.e., someone stepped on it), damaged mouths/necks and case head/rim damage. Some rifles’ ejectors actually dig small chunks of brass out of the case head — obviously, not ideal for precision shooting. Similarly, some extractors can bend the case rims so badly that distortion is visible when spinning them in one’s fingers. These can be used for plinking, but our match brass should have straight, undamaged rims.
Dented case mouths are common, and these can easily be rounded using a conical, tapered tool, [such as a .223 expander mandrel. A dummy 7.62 or .30-06 cartridge with a FMJ spitzer can also work.] If most of your brass is of one headstamp, this is a good time to cull out any odd cases.
4. Check the Primers Before Decapping
Your clean, dry and inspected brass is now ready for full-length sizing, decapping and re-priming. Historically, primer crimps on GI brass have caused some head-scratching (and vile language) among handloaders. Our next installment will detail efficient, easy and practical methods to remove primer crimp, plus other useful handloading tips. Until next week, Good Shooting!
Accuracy Potential of Mil-Surp 5.56×45 Brass
So, how accurate can previously-fired GI surplus brass be in a good National Match AR-15? Well, here’s a data point from many years ago that might be of interest. A High Power shooter who wrote for the late Precision Shooting magazine took a Bill Wylde-built AR match rifle to a registered Benchrest match. He had no difficulty obtaining consistent 0.5-0.6 MOA accuracy at 200 yards using LC brass and a generic “practice” load that was not tuned to his rifle.

In years past the U.S. Army Marksmanship Unit Facebook page regularly released reloading “how-to” articles each week. One “Handloading Hump Day” post covered bore-cleaning, specifically the use of pull-through style bore-snakes. Visit the USAMU Facebook page for other helpful tips.
Barrel Cleaning with Bore-Snakes
Today, we’ll shift from handloading to rifle bore cleaning and maintenance, with information courtesy of the USAMU’s Custom Firearms Shop. We recently had some inquiries about bore cleaning, and this seems a good opportunity to share. After all, even the best handloads won’t yield their full potential in a poorly-cleaned and maintained rifle.
NOTE: Hoppes claims a trademark on the term “BoreSnake” (one word, no hyphen). For this article, the USAMU has used the term in hyphenated form, two words. We believe the USAMU is referring to a Hoppes Brand Boresnake, not a different bore cleaning rope.
BORE-SNAKES: MIRACLE REPLACEMENT FOR THE CLEANING ROD?
The experiences of our both firearms test specialist and this writer have given no evidence that proper use of a clean bore-snake will damage a match barrel. Of course, one does not pull the bore-snake at an angle to the crown when removing it — pull it straight out, parallel to the bore’s direction, to prevent crown wear over time.
Bore-snakes are very useful for some applications (primarily a hasty, interim wipe-down). In [my] experience they cannot replace a thorough cleaning with a proper rod and brushes. While the experiment cited here involves rimfire, it may help illustrate. Several years ago, the writer used his new, personal Anschutz to investigate the bore-snake issue. It had been fired ~350 rds with match ammo and had had 3 typical rod/brush cleanings.
Next, starting with a clean bore, the writer fired 300 more rounds without cleaning in order to build up a “worst-case” fouling condition. Afterwards, the writer examined the bore with a Hawkeye bore scope. There was a uniform, grey film down the entire barrel, with some small, intermittent lead build-up at and just forward of the throat.
Some bore-cleaning rope products feature separate, detachable bronze brush and bore mop segments. This allows more usage options (e.g. mop only), and makes it easier to clean the brush elements:
A new bore-snake was then wet with solvent and pulled through the bore. The Hawkeye revealed that the grey fouling was gone, and much of the visible fouling at the throat was reduced. However, nine more passes with the bore-snake, checking after each with the Hawkeye, revealed no further improvement in cleaning. The writer then cleaned with two wet patches, observed, then one stroke of a new, wet bronze brush, and one wet patch to clean out residue.
The Hawkeye showed a significant reduction in fouling at the throat; it was virtually gone. A second pass with a wet bronze brush and a wet patch removed the remaining fouling. Scrubbing the bore further, checking to see how much fouling was removed, revealed no significant improvement. The reason for this test was to learn what’s needed to get (and keep) this Anschutz clean with minimal cleaning rod use — and thus, minimal risk of bore damage/wear. Leaving fouling in the bore promotes corrosion over time.
Obviously, this applies to a nice, smooth rimfire match barrel, using good, well lubed ammo. It doesn’t apply directly to the use of copper-jacketed bullets, which leave a stubborn fouling all their own. However, it does suggest that while the bore-snake can be helpful and a useful field-expedient, to truly clean a rifle barrel one will still need a good quality rod, bronze brush and solvents. [Editor: Add a good-fitting cleaning rod bore guide.]
SO, WHAT ABOUT BORE SNAKES FOR BARREL BREAK-IN?
The goal of barrel break-in is to fire each shot through a clean barrel, preventing copper buildup and allowing the bullets their best chance at burnishing sharp edges. Thus, it seems this purpose would be best served by one’s usual rods, brushes and rod guides.

In the past the U.S. Army Marksmanship Unit published a series of reloading “how-to” articles on its USAMU Facebook page. One “Handloading Hump Day” article covered two basic case prep chores — uniforming primer pockets and deburring flash-holes. Visit the USAMU Facebook page for other tips.
Primer Pocket & Flash-Hole Conditioning
This week, we’ll address a question that frequently arises: “Do you uniform primer pockets and deburr flash-holes?” As we tailor our handloading methods to the specific needs of each instance, the answer, not surprisingly, is “Sometimes!” However, don’t flip that dial just yet, as what determines our approach may be helpful in deciding how to address one’s own techniques. Moreover, we have a buried “Easter Egg” morsel that may bring a chuckle, as well as useful safety information!
Generally, the USAMU Handloading Shop does not uniform primer pockets (PP) or deburr flash holes (FH) of our rifle brass. We’re certainly not against it… Rather, this reflects the very high volume of ammunition we load, the fact that very few cases are ever re-loaded for a second firing, and the types of brass we use. However, as a need is perceived, we DO deburr flash holes. Of interest, we have fired many very small, 1000-yard test groups and aggregates using weight-selected, domestic brass that had not had PPs uniformed or FHs deburred.
Before and After — On the left is a fired, deprimed 7.62×51 case with primer residue intact. On the right the primer pocket has been uniformed to SAAMI specs. Note the shiny finish at the bottom of the pocket — evidence of the the removal of metal when uniforming the primer pocket.
As to the type cases we use, many thousands of our long-range 5.56mm cases come to us from the arsenal with the primer of our choice pre-installed and staked-in, per usual practice. Obviously, we cannot uniform either FHs or PPs on this live, primed brass. However, after careful sorting, inspection and preparation, we do obtain match-winning results with it.
Shooters who reload their brass several times may decide to uniform PPs and deburr FHs, especially on their “300-yard and beyond” brass. Here, they will use the cases many times, while the uniforming is performed only once. Also, most handloaders only process moderate amounts of brass, compared to our multi-thousand round lots.
Having high quality Long Range (LR) brass helps. Many of the better brass manufacturers [make] their flash holes so that no burrs are created. Still, it does pay to inspect even THESE manufacturer’s products, as occasional slips are inevitable. Very rarely, some of the best makers will have a significant burr in, say, 1 per 1000 or 2000 cases, and it’s worth catching those.
Exceptions can always be found. Recently, we began processing a large lot of match brass from a premier manufacturer. We were startled to find that every case had a significant burr in the FH — something we’d never before seen from this maker. We then broke out the FH deburring tools and went to work.
Some observers have noted that it can be difficult to truly verify the contribution to accuracy of these procedures — particularly when firing from the shoulder, in conditions. Members of this staff, as individual rifle competitors, do often perform these operations on their privately-owned LR rifle brass. One could ascribe this to the old High Power Rifle maxim that “if you think it helps, then it helps.”
However, a World Champion and Olympic Gold/Silver medalist here commented on his own handloading (for International competition, which demands VERY fine accuracy). He noted that he did seem to see a decline in accuracy whenever he did not uniform FHs, deburr FHs and clean primer pockets before each reloading. (One might be tempted to counter that only a truly World Class shooter could reliably detect the difference.) However, with the wisdom of decades experience, our Champion also remarked that “It could have been that I just wasn’t shooting as well that day.”
For those who do opt for these procedures, note that various tool models may have adjustable depth-stops; pay attention to the instructions. Some FH-deburring tools (which enter the case mouth, not the primer pocket) are dependent upon uniform case length for best results.
Above is a flash-hole deburring tool on an RCBS powered case-prep unit. These case prep machines can save a lot of pain and misery, helping one perform various functions quickly and efficiently.

Story by Paula Crenshaw
SFC Brandon Green of the U.S. Army Marksmanship Unit completely dominated the recent NRA Long Range Rifle Championships at Camp Atterbury, Indiana. Green finished as the 2022 Overall LR Champion, AND he won every other major individual Long Range Trophy — something that has NEVER been done before. With this truly dominant Long Range performance, along with his three previous National High Power Championships, Green has established himself, without a doubt, as one of the greatest American marksmen who has ever lived.
With this article, you can learn from SFC Green — sharing in his knowledge and amazing skill set. Today we feature a set of USAMU videos hosted by Brandon, with input from other top USAMU shooters. Watch, learn, and improve your game!
Marksmanship Video Training with SFC Brandon Green
The U.S. Army Marksmanship Unit (USAMU) has produced an excellent series of videos covering the Basic Rifleman’s Course. If you are getting started in High Power shooting, or want to improve your position shooting skills, this series is well worth watching. And these videos are not just for service rifle shooters — even bench shooters can benefit from these videos, particularly Part 5, which explains how to estimate wind speed and direction. The lead instructor for these videos is SFC Brandon Green, three-time National High Power Champion, and 2017 Service Rifle Champion. When SFC Green talks, you should listen.
SFC Brandon Green is a shooting superstar. Green won the National Long Range Championship this summer at Camp Atterbury, Indiana, winning every major trophy. Back in 2018, Green won his third NRA National High Power Rifle Championship in 2018, also at Camp Atterbury Brandon dominated the HP Championship cycle, finishing eight points and ten Xs ahead of his nearest competitor. Brandon also won High Power National Championships in 2015 and 2013. One of the greatest marksmen in the nation’s history, SFC Green excels at all positions, both rapid-fire and slow-fire.

SFC Brandon Green, 2022 National Long Range Champion, is congratulated by Mid Tompkins.
SFC Brandon Green of the U.S. Army Marksmanship Unit has added another remarkable achievement to his storied shooting career. In winning ALL the major Long Range events this summer, Green proved that he is one of the greatest American marksmen of all time. The USAMU’s Green, a three-time National High Power Champion, added multiple Long Range wins to his resume this summer. At the NRA National Matches in Camp Atterbury, Indiana, SFC Green won all four major “any rifle” trophies in the Long Range Championships. He was also the overall National Long-range Champion, winning the Tompkins trophy. No human had ever done that before. We congratulate Brandon on his amazing set of wins.
At Camp Atterbury this week, Brandon Green won all four NRA Long Range Individual National Trophies for Any Rifle: Wimbledon Cup, Mustin Trophy, Leech Cup, and Remington Band of Brothers Trophy. Green also won the Canadian Cup (National Any Rifle Champion) and Tompkins Trophy (overall National Long-Range Champion). No one has ever accomplished this feat in the history of the National Trophies. This is a truly historic individual performance by SFC Green, a fitting complement to his multiple High Power National Championships.
The Tompkins Trophy is a bronze statuette of a cowboy riding a horse while defending himself from an unseen pursuer. The work is entitled “Prayer and a Winchester” by L.E. “Gus” Shafer. The trophy was donated to NRA by Middleton W. Tompkins for Long Range High Power Rifle competition.

Efficient cartridges make excellent use of their available powder and case/bore capacity. They yield good ballistic performance with relatively little recoil and throat erosion.
Cartridge Efficiency: A Primer (pun intended!)by USAMU Staff
The U.S. Army Marksmanship Unit (USAMU) published a series of reloading articles on its Facebook Page. In this article, the USAMU discusses cartridge case efficiency and its benefits. While this is oriented primarily toward NRA High Power Rifle and Long Range (1000-yard) competition, these factors also apply to medium/big game hunters. Assuming one’s rifle and ammunition are accurate, key considerations include ballistic performance (i.e., resistance to wind effects, plus trajectory), recoil, and throat erosion/barrel life.
Efficient cartridges make excellent use of their available powder and case/bore capacity. They yield good ballistic performance with relatively little recoil and throat erosion. A classic example in the author’s experience involved a featherweight 7x57mm hunting/silhouette rifle. When loaded to modern-rifle pressures, just 43-44 grains of powder pushed a 139gr bullet at 2900 fps from its 22” barrel. Recoil in this light rifle was mild; it was very easy to shoot well, and its performance was superb.
An acquaintance chose a “do everything” 7mm Remington Magnum for use on medium game at short ranges. A larger, heavier rifle, it used ~65 grains of powder to achieve ~3200 fps with similar bullets — from its 26″ barrel. Recoil was higher, and he was sensitive to it, which hampered his shooting ability.
Similarly efficient calibers include the 6mm BR [Norma], and others. Today’s highly-efficient calibers, such as 6mm BR and a host of newer developments might use 28-30 grains of powder to launch a 105-107gr match bullet at speeds approaching the .243 Winchester. The .243 Win needs 40-45 grain charges at the same velocity.
Champion-level Long Range shooters need every ballistic edge feasible. They compete at a level where 1″ more or less drift in a wind change could make the difference between winning and losing. Shooters recognized this early on — the then-new .300 H&H Magnum quickly supplanted the .30-06 at the Wimbledon winner’s circle in the early days.
The .300 Winchester Magnum became popular, but its 190-220gr bullets had their work cut out for them once the 6.5-284 and its streamlined 140-142gr bullets arrived on the scene. The 6.5-284 gives superb accuracy and wind performance with about half the recoil of the big .30 magnums – albeit it is a known barrel-burner.
Currently, the 7mm Remington Short Action Ultra-Magnum (aka 7mm RSAUM), is giving stellar accuracy with cutting-edge, ~180 grain bullets, powder charges in the mid-50 grain range and velocities about 2800+ fps in long barrels. Beyond pure efficiency, the RSAUM’s modern, “short and fat” design helps ensure fine accuracy relative to older, longer cartridge designs of similar performance.
Recent design advances are yielding bullets with here-to-fore unheard-of ballistic efficiency; depending on the cartridge, they can make or break ones decision. Ballistic coefficients (“BC” — a numerical expression of a bullet’s ballistic efficiency) are soaring to new heights, and there are many exciting new avenues to explore.
The ideal choice [involves a] balancing act between bullet BCs, case capacity, velocity, barrel life, and recoil. But, as with new-car decisions, choosing can be half the fun!
Factors to Consider When Evaluating Cartridges
For competitive shooters… pristine accuracy and ballistic performance in the wind are critical. Flat trajectory benefits the hunter who may shoot at long, unknown distances (nowadays, range-finders help). However, this is of much less importance to competitors firing at known distances.
Recoil is an issue, particularly when one fires long strings during competition, and/or multiple strings in a day. Its effects are cumulative; cartridges with medium/heavy recoil can lead to shooter fatigue, disturbance of the shooting position and lower scores.
For hunters, who may only fire a few shots a year, recoil that does not induce flinching during sight-in, practice and hunting is a deciding factor. Depending on their game and ranges, etc., they may accept more recoil than the high-volume High Power or Long Range competitor.
Likewise, throat erosion/barrel life is important to competitive shooters, who fire thousands of rounds in practice and matches, vs. the medium/big game hunter. A cartridge that performs well ballistically with great accuracy, has long barrel life and low recoil is the competitive shooter’s ideal. For the hunter, other factors may weigh more heavily.
Cartridge Efficiency and Energy — Another Perspective
Former Lapua staffer Kevin Thomas explains that efficiency can be evaluated in terms of energy:
“Cartridge efficiency is pretty straight forward — energy in vs. energy out. Most modern single-based propellants run around 178-215 ft/lbs of energy per grain. These figures give the energy potential that you’re loading into the rifle. The resulting kinetic energy transferred to the bullet will give you the efficiency of the round. Most cases operate at around 20-25% efficiency. This is just another way to evaluate the potential of a given cartridge. There’s a big difference between this and simply looking at max velocities produced by various cartridges.”

This USAMU article explores three different “Philosophies” of precision reloading. Some handloaders seek to produce ammo that yields the very tightest groups (without factoring in the wind). Other shooters load their ammo to deliver the highest safe velocity. That’s because a projectile launched at higher velocity will drift less in the wind. The theory is that even if fast ammo doesn’t produce the tightest groups in zero wind conditions, it will yield higher scores in a the real world (where the wind blows). Lastly, some handloaders favor ammo that is ultra-consistent across a wide temperature range. This last philosophy dictates selection of a powder that is temp-insensitive, even if it may not produce the very best raw accuracy (or speed).
What’s Your Handloading Philosophy?
Objectives of Reloading — Accuracy, Velocity, Temp Stability What do you, the reader, primarily value in your handloads?
Viewpoint ONE: Accuracy Trumps Everything
Some shooters prize consistent, excellent medium/long range accuracy enough that they’re willing to give up some extra velocity (and reduced wind deflection) to obtain that. Their underlying philosophy could be stated: “Superior accuracy is present for every shot, but the wind isn’t”. One’s ability to hold well, aim well and read the wind are all factors in making this type decision. The photo below shows stellar raw accuracy. This is an 0.67″, 10-shot group at 300-yards fired from a text fixture. The group measures just 0.67″. (This shows the USAMU’s 600-yard load with 75gr bullets).
Viewpoint TWO: Load to Highest Safe Velocity for Less Wind Drift
Some shooters value obtaining the highest safe velocity, even if one’s pure, consistent mechanical accuracy at medium/long range isn’t quite as brilliant. The theory here seems to be that a really good hold extracts as much mechanical accuracy from the rifle/ammo as possible, and faster bullets equal occasional “bonus” points snatched from the jaws of wind.
[For example] one of the USAMU’s many Service Rifle National Champions revealed his philosophy. It can be stated thus: a super-accurate, but [relatively] “slow” load “required him to have a Ph.D. in wind reading for every shot, while a faster, but less accurate load netted him more points.”
Note — this was not mere speculation; his score book data backed up his claims, due to less wind effects. Remember, however, this fellow has a consistent, National Championship-level hold, and other Champions on the same team would have opted differently.
Viewpoint THREE: Temperature Stability Is Key
Still another approach is to place heavy emphasis on fine accuracy with absolute stability in changing temperatures. When this writer was actively earning his Distinguished Rifleman badge, that was his goal. The reason? Sighting shots are not allowed in EIC (“Leg”) matches. The first shot out of the barrel was for score. It had to be 100% consistent, with very reliable, predictable elevation and wind deflection regardless of the ambient temperature — even if it wasn’t the lowest wind deflection possible.
Naturally, selecting a powder that is insensitive to temperature changes is a key element here. Elevation zeros and wind effects HAD to be consistent every time. Hunters and military snipers might be among those who fall into this camp, as well as those in pursuit of their Distinguished Rifleman badges.
Contrast that with a traditional High Power shooter who gets two sighter shots before each event (offhand, sitting rapid, prone rapid, prone slow fire.) If there is a zero change on any given day, he/she can correct during sighters. This writer well remembers talking with another very high-level Service Rifle competitor who was happy to have high temperatures boost the velocities of his ammunition above their usual level… As far as this SR competitor was concerned, 60-80 fps more velocity -– even if only due to high ambient temperatures -– meant less wind deflection, and he was mighty happy to have it.
Particularly in the summer, with hot daily conditions, you need to be concerned about temperature stability. Loads worked up in winter may not work in the summer time.
This article has been confined to NRA High Power Rifle competition, which has relatively generous 10-ring dimensions in relation to the accuracy of well-built competition rifles. Hopefully, it will provide food for thought. For some, this might be an opportunity to ensure that one’s load development approach helps them attain their desired results.

The following article by Tom Alves describes a very practical approach to physical training for those of us who are not as young and spry as we once were. Tom shows us how to give our bodies at least some of the maintenance we give our rifles. While we all realize that our rifles will outlive us, let’s see if we can’t narrow the margin a bit with some personal maintenance that just might help the shooting too!
This article originally appeared in German Salazar’s Rifleman’s Journal, and appears with permission. Sadly, German passed away last month. This was a very sad loss of a great, triple-distinguished shooter and a great shooting sports writer.
A Suggested Training Approach for Older Shooters
By Tom Alves Most articles and discussions regarding competitive shooting center around equipment. Now and then one will come across an article about physical training such as the USAMU piece on Physical Conditioning for Highpower Shooting. If you break the articles down they often discuss “core strength” and durability. The purpose of this paper is to elaborate on those points with a bit different perspective. Many of the articles you will read in books about position shooting and the one mentioned before are directed more toward the younger generation of shooters in their 20s. If you look down the line at a typical high power match these days you are likely to see quite a few folks who are in their middle 30’s and up. Many people in that age range have had broken bones and wear and tear on their joints so a training program needs to take that into account. For instance, while jogging for an extended period for heart and lung conditioning — often called cardio exercises — may be the recommended approach for younger folks, it may be totally inappropriate for older people. The procedure to repair meniscus tears in knees is one of the most frequently performed operations in this country. Another approach one often sees in training to improve core strength is the use of weight machines which isolate certain muscle groups in their operation. I would like to suggest an alternative approach that not only does not require special equipment but uses the body’s muscles in a coordinated fashion in the same way they are used in our natural movements. So, let’s set down some criteria:
1. The approach has to be low impact to conserve joints.
2. One goal is to improve the strength of the core muscles which are the muscles of our trunk that keep us erect and from where all movements initiate.
3. Along with core strength we need flexibility and full range of motion.
4. We want to improve our lung and heart function so we can have a good flow of oxygen going to our organs and muscles to reduce the rate at which we become fatigued during a competitive event.
Before I continue I believe it is appropriate for the reader to understand that I am a fellow shooter and this is a program I have designed for myself based on considerable reading and experience over a number of years. I am not a medical doctor, a formally trained exercise professional or any other type of specialist in the field. Consequently, this information is offered with the advice that you consult your medical advisor or similar authority before you embark on this or any similar regimen.
I will start with core strength and flexibility. Pilates exercises are resistance exercises that can incorporate the use of resistance bands, light weights and the weight of your body parts in order to strengthen the muscles in the abdomen, back, hips, chest and shoulders. The exercises can be performed alone but I recommend attending classes put on by a certified instructor who will ensure that you perform a balanced routine meaning you work on the front and back and both sides of your trunk. As to flexibility, yoga complements Pilates exercises and they are often taught together. In practical terms yoga strengthens through resistance using the weight of the body and increases flexibility by stretching the various muscle groups in a coordinated fashion. Some yoga exercises also work on balance which is helpful in position shooting and life in general. Again, I suggest attending formal yoga classes since an instructor can help you address such things as a joint misalignment. As an example, my right leg healed improperly after the femur was broken and my right foot splays out putting undue load on my left knee. There are a number of books available on Pilates and yoga and some of them get pretty involved; I leave that to the reader to explore. I will list some reference material at the end of the article that I have found useful.
Finally, heart and lung improvement. In order to exercise the heart and lungs while not abusing the joints, particularly the knees and hips, one has to resort to something other than jogging. Walking, bicycling, elliptical machines and swimming may be alternative methods you’d like to consider. Based on my reading, in order to get the most benefit it is important to exercise so that the pulse rate becomes elevated for periods of time rather than kept at a constant rate. The process I use, called PACE, is promoted by Al Sears, MD, http://www.alsearsmd.com/. It is interval training for the non-athlete. In simple terms one exercises, using whatever equipment one desires, to achieve a heart rate in which you are slightly above your ability to bring enough oxygen into your body to sustain the activity for an extended period. This is similar to wind sprints for a sprinter or a football player. After each episode you must rest until you have achieved recovery, meaning you can catch your breath easily. A series of three sets is recommended which covers a total time of about 20 minutes.
Report from the Author — Yes, Training Helps
As a result of this training program I have experienced increased strength in my legs and trunk, less joint stiffness, lower blood pressure, and lower resting pulse rate. The Pilates/yoga classes are usually attended 2 to 3 times a week and the interval training performed twice a week. [The author was 64 when this was first published. He is now 75, and still shooting Palma and Smallbore prone.]
Before I close I would like to touch briefly on two other related subjects: hydration and visual training. When one is exerting oneself, the body produces perspiration to keep the body’s temperature at an acceptable level. As one perspires the blood gets thicker and the ocular fluid in one’s eyes thickens as well. The heart has to work harder to supply oxygen and nutrients to the body so visual and cognitive functions degrade and fatigue sets in rapidly. Essential chemicals called electrolytes are also carried out of the body with the perspiration. As a result, it is necessary to replace moisture and electrolytes to maintain basic health and a competitive level of performance. If one goes on the Internet there is a multitude of articles on hydration. Due to the kindness of my lead Pilates/yoga instructor, Ms. Annette Garrison, I have a pretty comprehensive article on various aspects of hydration that I have included, http://www.ideafit.com/fitness-library/hyponatremia-other-side-hydration-story , for your information.
Last I want to mention visual performance training. The New Position Rifle Shooting, A How-To Guide for Shooters and Coaches by Bill Pullum and Frank Hanenkrat mentions sports vision training amongst other aspects of vision in competitive shooting. If one goes on the Internet you will find training programs directed at golfers, baseball and football players. There is one site that has a demo which, if one looks at it for long, it is obviously very similar to a shooting gallery video game. The training involves rapid recognition and hand-eye coordination. Another source of visual training exercises, along with a wealth of other information, is the book Prone And Long Range Rifle Shooting by Nancy Tompkins.
Hopefully, I have provided some information which will be helpful in improving shooting performance and extending the time you can participate at a competitive level. It is important that you proceed at your own pace. I have pushed myself too hard in the interval training and now have to back off a bit. In closing I would like to thank Annette Garrison and GS Arizona for their help, patience and encouragement.

Bore-snakes are very useful for some applications (primarily a hasty, interim wipe-down). In [my] experience they cannot replace a thorough cleaning with a proper rod and brushes. While the experiment cited here involves rimfire, it may help illustrate. Several years ago, the writer used his new, personal Anschutz to investigate the bore-snake issue. It had been fired ~350 rds with match ammo and had had 3 typical rod/brush cleanings.
