Editor’s Note: The CMP National Matches at Camp Perry are less than a month away. This article covers key points for rifle competitors at major matches. To do well, you want to be an “informed competitor” with a positive attitude and full knowledge of the course of fire and match rules.
Don’t Be “That Guy” (The Bad Apple on the Firing Line)
By SFC Norman Anderson, USAMU Service Rifle Team Member
You know the guy, he’s still talking at the coffee jug when his preparation period begins, then his magazines aren’t loaded when the command “STAND” is given, and finally, he doesn’t know the rules when he argues with the block officer as his target comes up marked “9 and No”. Although this guy might be the highlight of the “after match” activities, he is the proverbial bad apple on the firing line. With this example fresh in your mind, let’s go over how not to be “that guy”.
While the sport of High Power shooting is a hobby for most, all are passionate about performance throughout the day. In order to achieve your maximum performance each and every day, it is essential that you conduct yourself as a professional competitor. As a competitor, you have a personal responsibility to know the course of fire as well as the rules and procedures that apply to it and to be prepared to follow them. Knowing this will not only make you a better competitor, but it will enable you to resolve situations with other targets besides your own. So what does all this mean? I’ll explain…
Know the Course of Fire
Know the course of fire. It sounds easy enough, as we all shoot plenty of matches, but it’s more than that. If you think about it, how many people in the pits, for example, do not really know what is happening on the firing line? This leads to targets being pulled early during a rapid fire string or missing a shot during a slow fire string. In cases like this, the result is the same, delays in the match and upset competitors. To avoid being “that guy,” it is imperative that you stay tuned to the events as the day progresses. When you are at the range shooting a match, be at the range shooting the match.
At any firearms competition — be sure you know (and understand) the course of fire.
Know the Rules
Now, let’s discuss rules. As you have probably heard more than once, the rulebook is your best friend. Here is why. I can virtually guarantee that most competitors know some of the rules based only on the old “this is how we do it at home” adage. The funny part of that is, the same green NRA rulebook and orange CMP rulebooks are used to govern High Power matches all over the country.*
It is vital that all shooters be familiar with the rules as they are written, not with “how they are applied at home”. This creates consistency and continuity in how matches are conducted, from local club matches to state tournaments to National Championships. Knowledge is power when it comes to scoring targets under contention, what to do in the case of a malfunction, or even how to file a protest correctly. These rules are in place for a reason and it benefits everyone to both know and operate by these rules.
Maintain Composure and Humility — Exhibit Good Sportsmanship
One aspect of competing that cannot be forgotten is bearing. As I mentioned earlier, you must be prepared for both good and bad to happen. All too often we all see “that guy” (or that “that guy’s” gear) flying off of the firing line in disgust. Remember that we all must maintain our composure and humility in all conditions, not matter what happens. After all, it’s just a game. To put it into perspective, if it were easy, attendance would be a lot higher. Sportsmanship must be displayed in an effort to keep from ruining the day for all those around you. It doesn’t cost anything to smile, and smiling never killed anyone. So turn that frown upside down and keep on marching, better days will come.
Like a Boy Scout — Always Be Prepared
Lastly, I would like to cover preparedness. Being prepared goes beyond simply having your magazines loaded and a zero on your rifle. It means approaching the firing line, knowing what you are about to do, being ready for what is going to happen (good or bad), and being ready for the results. If you approach the firing line to merely shoot 10 shots standing in your next LEG match, you are not going to be pleased with the result. You must be prepared mentally and physically, not only for the next stage, but also the next shot. By being prepared physically (equipment ready), you give yourself peace of mind which is an essential part of being prepared mentally, and by being prepared mentally, you are less likely to become distracted and are more likely to maintain focus for each and every shot.
Conclusion — Informed Competitors Make for Better Matches
The culmination of these efforts results in a shooter that knows how to be ready for success on the range, but also and perhaps more importantly, a shooter who knows what it means to be a competitor. When you have a range full of competitors who know and follow the rules and proper match procedures, the match runs smoothly, everyone shoots well, and a good time is had by all. In the end, isn’t that what it’s all about?

Precision Pistol Reloading — Recommended Methods
Optimize the Taper Crimp
One often-overlooked aspect of handloading highly-accurate pistol ammunition is the amount of crimp and its effect on accuracy. Different amounts of taper crimp are used with various handloads to obtain best accuracy. The amount is based on bullet weight, powder burn rate and charge, plus other factors. It is not unusual for our Shop to vary a load’s crimp in degrees of 0.001″ and re-test for finest accuracy.
Use Consistent Brass
Brass is also important to pistol accuracy. While accurate ammunition can be loaded using brass of mixed parentage, that is not conducive to finest results, particularly at 50 yards. It is important for the serious competitor/handloader to use brass of the same headstamp and ideally one lot number, to maximize uniformity. Given the volumes of ammunition consumed by active pistol competitors, using inexpensive, mixed surplus brass for practice, particularly at the “short line” (25 yards), is understandable. However [at 50 yards], purchasing and segregating a lot of high-quality brass to be used strictly for slow-fire is a wise idea.
Importance of Uniform COAL
Uniformity of the Case Overall Length (COAL) as it comes from the factory is also important to achieving utmost accuracy. More uniform case lengths (best measured after sizing) contribute to greater consistency of crimp, neck tension, ignition/burn of powder charge, and so on. Cartridge case-length consistency varies from lot to lot, as well as by maker. Some manufacturers are more consistent in this dimension than others. [Editor’s note: It is easy to trim pistol brass to uniform length. Doing this will make your taper crimps much more consistent.]
Primers and Powders — Comparison Test for Accuracy
Pay attention to primer brands, powder types and charges. Evaluating accuracy with a Ransom or other machine rest at 50 yards can quickly reveal the effect of changes made to handload recipes.
Bullet Selection — FMJ vs. JHP
Bullets are another vital issue. First, there is the question of FMJ vs. JHP. A friend of this writer spent decades making and accuracy-testing rifle and pistol bullets during QC for a major bullet manufacturer. In his experience, making highly-accurate FMJ bullets is much more difficult than making highly-accurate JHPs, in large part due to the way the jackets are formed. Small die changes could affect accuracy of FMJ lots dramatically. The CMP now allows “safe, jacketed ammunition” in Excellence-in-Competition (EIC) Service Pistol matches, although wadcutter ammunition is prohibited. Thus, the option to use very accurate JHP designs simplifies the life of CMP Service Pistol shooters in pursuit of the prestigious Distinguished Pistol Shot badge.
Hopefully, these tips will be helpful to any pistol shooters interested in accurate handloads, not just “Bullseye” shooters. Small tweaks to one’s normal routine can pay big dividends in improved accuracy and make practice and competition more rewarding. Stay safe, and good shooting!

Share the post "Precision Reloading for Competition Pistols — Tips from USAMU"
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.

Photo 1: Three Near-Equal-Weight 7mm Bullets with Different Shapes
TECH TIP: Bullets of the same weight (and caliber) can generate very different pressure levels due to variances in Bearing Surface Length (BSL).
This article, from the USAMU Facebook Page, concerns reloading safety. In the relentless quest for more speed and flatter ballistics, some hand-loaders load way too hot, running charges that exceed safe pressure levels. Hint: If you need a mallet to open your bolt, chances are your load is too hot. Stay within safe margins — your equipment will last longer, and you won’t risk an injury caused by over-pressure. In this article, the USAMU explains that you need to account for bullet shape, diameter, and bearing surface when working up a load. Don’t assume that a load which is safe for one bullet will be safe for another even if both bullets are exactly the same weight.
How Bullet Profile and Bearing Surface Affect Pressure Levels
Today, we continue our handloading safety theme, focusing on not inadvertently exceeding the boundaries of known, safe data. Bullet manufacturers’ loading manuals often display three, four, or more similar-weight bullets grouped together with one set of load recipes. The manufacturer has tested these bullets and developed safe data for that group. However, seeing data in this format can tempt loaders — especially new ones — to think that ALL bullets of a given weight and caliber can interchangeably use the same load data. Actually, not so much.
However, bullet designs include many variables such as different bearing surface lengths, hardness, and even slight variations in diameter. In fact, diameters can occasionally range up to 0.001″ by design. Thus, choosing untested bullets of the same weight and caliber, and using them with data not developed for them can yield excess pressures.
This is only one of the countless reasons not to begin at or very near the highest pressure loads during load development. Always begin at the starting load and look for pressure signs as one increases powder charges.
Bullet Bearing Surface and Pressure
Bullet bearing surface length (BSL) is often overlooked when considering maximum safe powder charges and pressures. In Photo 1, note the differences in the bullets’ appearance. All three are 7 mm, and their maximum weight difference is just five grains. Yet, the traditional round nose, flat base design on the left appears to have much more BSL than the sleeker match bullets. All things being equal, based on appearance, the RN/FB bullet seems likely to reach maximum pressure with significantly less powder than the other two designs.
TECH TIP: Bullets of the same weight (and caliber) can generate very different pressure levels due to variances in Bearing Surface Length (BSL).
Bullet 1 (L-R), the RN/FB, has a very slight taper and only reaches its full diameter (0.284 inch) very near the cannelure. This taper is often seen on similar bullets; it helps reduce pressures with good accuracy. The calculated BSL of Bullet 1 was ~0.324″. The BSL of Bullet 2, in the center, was ~0.430″, and Bullet 3’s was ~ 0.463″. Obviously, bullets can be visually deceiving as to BSL!
Some might be tempted to use a bullet ogive comparator (or two) to measure bullets’ true BSL for comparison’s sake. Unfortunately, comparators don’t typically measure maximum bullet diameter and this approach can be deluding.
Note: Due to time constraints, the writer used an approximate, direct measurement approach to assess the bullets’ different BSLs. While fairly repeatable, the results were far from ballistics engineer-grade. Still, they are adequate for this example.
Photo 2: The Perils of Measuring Bearing Surface Length with Comparators
In Photo 2, two 7mm comparators have been installed on a dial caliper in an attempt to measure BSL. Using this approach, the BSLs differed sharply from the original [measurements]. The comparator-measured Bullet 1 BSL was 0.694” vs. 0.324” (original), Bullet 2 was 0.601” (comparator) vs. 0.430” (original), and Bullet 3 (shown in Photo 2) was 0.602” (comparator) vs. 0.463” (original). [Editor’s comment — Note the very large difference for Bullet 1, masking the fact that the true full diameter on this bullet starts very far back. You can use comparators on calipers, but be aware that this method may give you deceptive reading — we’ve seen variances just by reversing the comparators on the calipers, because the comparators, typically, are not perfectly round, nor are they machined to precision tolerances.]

Nikon offers eyepieces with reticles for its flagship Monarch Fieldscopes. Eyepiece reticles help spotters call shot corrections with precise click values (MOA or Mils).
Using a spotting scope seems simple. Just point it at the target and focus, right? Well, actually, it’s not that simple. Sometimes you want to watch mirage or trace, and that involves different focus and viewing priorities. Along with resolving bullet holes (or seeing other features on the target itself), you can use your spotting scope to monitor mirage. When watching mirage, you actually want to focus the spotting scope not on the target, but, typically, about two-thirds of the distance downrange. When spotting for another shooter, you can also use the spotting scope to watch the bullet trace, i.e. the vapor trail of the bullet. This will help you determine where the bullet is actually landing, even if it does not impact on the target backer.
In this video, SFC L.D. Lewis explains how to use a spotting scope to monitor mirage, and to watch trace. SFC Lewis is a former Army Marksmanship Unit member, U.S. Army Sniper School instructor, and current U.S. Army Reserve Service Rifle Shooting Team member. In discussing how precision shooters can employ spotting scopes, Lewis compares the use of a spotting scope for competition shooters vs. military snipers.

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 in 2022. This was a very sad loss of a distinguished-class marksman and a great shooting sports writer. This Editor counted German as a close friend, who helped this site in many ways.
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. [Book under $40.00 on Amazon]. 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 German Salazar for their help, patience and encouragement.

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 USAMU has published a “how-to” article about bullet sorting. While many of us may sort bullets by base-to-ogive length (and/or weight), the USAMU story explores the “how and why” of sorting bullets by Overall Length (OAL). Read the article highlights below, and make your own decision as to whether OAL sorting is worth the time and effort. Bryan Litz of Applied Ballistics says that sorting by OAL is not a bad idea, but base-to-ogive bullet sorting probably represents a better investment of your time.
Bullet Sorting by Overall Length
We’d like to share a specialized handloading technique which we’ve long found beneficial to our long-range (600 yards and beyond) accuracy. Sorting of bullets for extreme long range (LR) accuracy is not difficult to do, but some background in theory is needed.
Here at USAMU’s Handloading Shop, we only sort individual bullets for the most demanding Long-Range applications and important competitions. Only the most accurate rifles and shooters can fully exploit the benefits of this technique. The basic sorting process involves measuring the Overall Length (OAL) of the bullets, and grouping them in 0.001″ increments. It’s not unusual to find lots of match bullets that vary as much as 0.015″-0.020″ in length throughout the lot, although lots with much less variation are seen as well. Even in bullet lots with 0.015″ OAL variation, the bullet base-to-ogive length will show much less variation. Hence, our basic sort is by bullet OAL. One obvious benefit of sorting is easily seen in the attached photo. The few bullets that are VERY different from the average are culled out, reducing probable fliers.
How does one know what OAL increments to use when sorting? The answer is simple. As each lot of bullets is unique in its OAL distribution, it’s best to sample your bullet lot and see how they are distributed. In the attached photo, you will see a set of loading trays with a strip of masking tape running along the bottom. Each vertical row of holes is numbered in 0.001″ increments corresponding to the bullets’ OAL. A digital caliper makes this task much easier. As each bullet is measured, it is placed in the line of holes for its’ OAL, and gradually, a roughly bell-shaped curve begins to form.
Note that near the center, bullets are much more plentiful than near the edges. At the extreme edges, there are a few that differ markedly from the average, and these make great chronograph or sighting-in fodder. We recommend using a sample of 200 bullets from your lot, and 300 is even better. Some bullet lots are very consistent, with a tall, narrow band of highly-uniform bullets clustered together over just a few thousandths spread. Other lots will show a long, relatively flat curve (less uniform), and you may also see curves with 2 or more “spikes” separated by several 0.001″ OAL increments.
Bullet Sorting — OAL vs. Base-to-Ogive vs. Weight
Expert advice from Bryan Litz, Applied Ballistics
I’m often asked what is a the best measure to sort bullets by, and the answer (to this and many other questions in ballistics) is: it depends.
Choosing to sort by overall length (OAL), base to ogive (BTO), bearing surface, weight, etc. can get overwhelming. Shooters typically look for something they can measure, which shows a variation and sort by that. It’s common for dimensional variations to correlate. For example, bullets which are longer in OAL are typically also shorter in BTO, and have longer noses. All these are symptoms of a bullet that was pushed a little further into the pointing die, or possibly had more than average lube while being swaged. So in essence, if you sort by BTO, you’re measuring one symptom which can indicate a pattern in the bullets shape.
So, the question still stands — what should you measure? You’ll always see more variation in OAL than BTO, so it’s easier to sort by OAL. But sometimes the bullet tips can be jagged and have small burrs which can be misleading. Measuring BTO will result in a lower spread, but is a more direct measure of bullet uniformity.
Then there’s the question of; how much variation is too much, or, how many bins should you sort into? Shooters who see 0.025” variation in BTO may choose to sort into 5 bins of 0.005”. But if you have only 0.005” variation in the box, you’ll still sort into 5 bins of 0.001”. What’s correct? You have to shoot to know. Live fire testing will answer more questions, and answer them more decisively than any amount of discussion on the subject. The test I recommend is to identify bullets on the extreme short end of the spectrum, and some on the extreme long end. Load at least 10 rounds of each, and take turns shooting 5-shot groups with them. If there is a difference, it will be evident. The results of the testing will answer your question of: should I sort based on X, Y, or Z?”

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.

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!

For many years, the U.S. Army Marksmanship Unit (USAMU) regularly published reloading “how-to” articles on the USAMU Facebook page. In this article, the USAMU’s reloading gurus address a question frequently asked by prospective handloaders: “Should I buy a single-stage press, or a progressive?” The USAMU says the best answer is Solomon-esque in both its wisdom and simplicity: “Get BOTH!” However, there is definitely more to the issue, as the USAMU explains below.
Progressive Press Safety Considerations
by USAMU Staff
Many are the beginning handloaders who have asked a friend about their “setting up” a progressive press for them. The idea is that the newbie could then just feed in components and crank out buckets of practice ammo without needing to really learn much about handloading. Tempting though this might be, that’s simply not how it works. Such an approach might be ok if there were never a malfunction with either press or operator, but that’s unrealistic. Our hypothetical newbie would then lack the knowledge to problem-solve most situations.
Worse yet, several different handloading operations would be occurring at different stations on the progressive press at the same time. It takes an experienced operator to keep track of, and truly understand the significance of, all those potential mini-problems. Loading without this experience is a recipe for potential disaster – such as a double powder charge (especially with pistol cartridges) dropped while the loader was attending to some other function, etc. Progressives are an animal unto themselves, and while they offer many benefits, they do take some getting used to – even by experienced handloaders!
ILLUSTRATIVE HORROR STORY
Here, enter a 40-year veteran handloader who decided to jump onto the progressive bandwagon late in his career, having used only single-stage presses all his life. A High Master NRA High Power Rifle competitor, he had no background in competitive pistol shooting, where historically most progressive presses are found.
Experienced Action Pistol shooters have typically encountered multiple episodes in which shooters “skipped” a powder charge for some reason, leading to a squib round and a bullet possibly lodged in the bore. Thus, at matches, it’s reflexive for them to yell “STOP!” in unison if they see a shooter get a “click” vs. a “bang”, and rack the slide to keep firing. This writer has personally seen several pistols saved in just such scenarios over the years.
Click No Bang — What NOT to Do
Our High Master set up a popular progressive press and began turning out .223 Rem 100-yard practice ammo with abandon. He was using a moly-coated 52gr match bullet and an economical, fast-burning surplus powder that gave great accuracy. Once on the range, he began practicing strings of rapid-fire. All was well, until he heard “Click!” rather than “Boom”.
Lacking the above experience or onlookers to halt him, he reflexively operated the charging handle on his expensive, custom NM AR15 Service Rifle, and the next trigger squeeze reportedly registered on seismographs over at least a three-state radius. He sat, uninjured but bewildered, until the hail of expensive bits and pieces quit raining down around him.
When the smoke cleared, he immediately cursed the horrid, evil, demonically-possessed progressive press for this, his first-ever reloading mishap. His $1400 NM upper was ruined, but thankfully, his $800 pre-ban lower… and he had escaped injury.
This tale is told not to discourage the use of progressive presses, but to emphasize the need to EASILY and IMMEDIATELY KNOW what is happening with the press at each station, every time the handle is cranked. Not to do so is, as they say, “bad ju-ju.”
It illustrates why we at the USAMU Handloading Shop agree in recommending that new handloaders should begin with a single-stage press. Once one thoroughly learns the steps in each phase of handloading by repeated experience, then one will be qualified to move on to a progressive press.
The single-stage press will REMAIN virtually indispensable for one’s entire handloading career, even after having purchased a progressive press (or two). There are endless small projects that are best handled on a single-stage press, and a poll of USAMU’s Handloading staff reveals that not one would willingly be without his single-stage press, despite owning at least one progressive.

Know the Rules
Use Consistent Brass
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. 
Bullet 1 (L-R), the RN/FB, has a very slight taper and only reaches its full diameter (0.284 inch) very near the cannelure. This taper is often seen on similar bullets; it helps reduce pressures with good accuracy. The calculated BSL of Bullet 1 was ~0.324″. The BSL of Bullet 2, in the center, was ~0.430″, and Bullet 3’s was ~ 0.463″. Obviously, bullets can be visually deceiving as to BSL!
Using a spotting scope seems simple. Just point it at the target and focus, right? Well, actually, it’s not that simple. Sometimes you want to watch mirage or trace, and that involves different focus and viewing priorities. Along with resolving bullet holes (or seeing other features on the target itself), you can use your spotting scope to monitor mirage. When watching mirage, you actually want to focus the spotting scope not on the target, but, typically, about two-thirds of the distance downrange. When spotting for another shooter, you can also use the spotting scope to watch the bullet trace, i.e. the vapor trail of the bullet. This will help you determine where the bullet is actually landing, even if it does not impact on the target backer.
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
