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?
* After this article was originally written, the CMP separated its rules into multiple Rulebooks, which can all be downloaded from the CMP.org/rulebooks page:
The CMP Highpower Competition Rules 2024 (27th Ed.) for CMP-sponsored and sanctioned matches for Highpower Rifle events in National Trophy Matches, Excellence-In-Competition (EIC) Matches, CMP Cup Matches and other CMP-sanctioned competitions.
The CMP Pistol Competition Rules 2024 (27th Ed.) for CMP-sponsored and sanctioned Pistol Matches in the National Matches, National Trophy Matches, Excellence-In-Competition (EIC) Matches, and other CMP-sanctioned competitions.
The First Shot, the CMP’s archived Online magazine, has an article by Spc. Tyrel Cooper of the U.S. Army Marksmanship Unit (USAMU). In his article, Straight to the Rear, Spc. Cooper describes proper trigger hand and finger positions and how to best “break the shot”. This well-written article will help anyone who shoots off-hand, or who uses an AR or Spacegun-type rifle with a vertical pistol grip.
Cooper explains: “Trigger control is one of the two main principles of shooting that we teach. You can have the best position in the world with perfect sight alignment, but if you have bad trigger control, you have wasted all that effort that you put into your position and sight alignment.”

Firing Hand Position and Finger Placement
“Good trigger control begins with a good firing hand position. Place your firing hand high on the pistol grip, with a good firm grip. Grip tension should be like giving someone a hand shake or holding a child’s hand while walking across a street. A good firm grip [helps you] move your trigger finger without moving your other fingers. Try this, hold out your firing hand with fingers extended; now try moving your trigger finger to the rear as if you were pulling the trigger. Unless you concentrate very hard on moving just your trigger finger, other fingers will move. Now make a fist as if you were grabbing a pistol grip, now you can move your trigger finger freely without introducing movement in the other fingers.”
“I’m sure you have heard advice to place the tip or the pad of your finger on the trigger. This is true if you have short stubby fingers and that’s where the index finger naturally rests, but if you have long fingers like myself you want more of your finger around the trigger…. By placing your finger where it naturally rests on the trigger you are ensuring that you are pulling the trigger straight to the rear, and this also allows you to get more leverage on the trigger.”
Rapid-Fire Trigger Technique
“Trigger control for the rapid-fire stage is different than it is for standing. You can actually take a little bit more time to break your shots in rapid fire because of the steadiness of a supported position. A good rapid fire shot process is: 1) drop down into position, 2) get your natural point of aim, 3) take up the first stage on your first shot, 4) break that shot smoothly and hold the trigger all the way to the rear through recoil, 4) once recoil has ceased, let the trigger out only far enough to reset the trigger (you should hear a metallic click of the trigger resetting) and continue by firing your second and succeeding shots.
By doing this, you already have most of the weight of the trigger taken up so the next shot is ready to go without having to take up all the weight of the trigger every single shot.”
Slow-Fire Prone Technique
“During the slow fire prone stage, you have even more time to break your shots, so you would use the slow–smooth method. You should have little or no hold movement at all, thus allowing you to acquire good sight alignment, a good sight picture and break the shot using slow and smooth trigger control. Again you want to hold that trigger all the way to the rear until recoil has ceased so you do not disturb the rifle, no matter what position you are shooting.”
Standing Trigger Technique
“When you are shooting standing have you noticed that the rifle never really stops moving? Well, this is where you would want fast and smooth trigger control. When I come down and start settling on the target, I take up the first stage of the trigger. Once I’m getting to the end of my firing process and the movement has slowed down, I manipulate the trigger fast, but smooth, to the rear when I see what I want to see in my sight picture. Over time, this will become a subconscious act; when your brain sees the sight picture, it will automatically tell your trigger finger to move instead of you having to tell yourself there it is, take it. Lots and lots of dry firing will help this process. To repeat, you want to be fast and smooth!”
Retro is back — at least in the CMP’s Standard Modern Military Rifle AR class. Though Service Rifle competition has evolved to allow optics and heavy barrel profiles, the Standard Modern Military Rifle (AR category) is truly a “blast from the past”. Overall weight is limited to 7.5 pounds, and the rifle must be equipped with iron sights (Rule 5.2.3). In addition, the rifle must “be based on the M-16 rifle or be based on an AR design” with “exterior configuration similar [to] the original military or military-type rifle”. See Rules.
With this in mind our friend Dennis Santiago has put together his own AR-platform Standard Modern Military Rifle for matches run under CMP Games Competition Rules. This is not quite a classic AR, as it has a metal free-float handguard (vs. plastic handguards), but it IS light (7.3 pounds), and it does have iron sights — a key requirement for Standard Modern Military class rifles. CMP Rulebooks — All Classes.
Here is Santiago’s CMP Modern Military Rifle (Standard Class) with an ultralight free float tube that has a titanium barrel nut, and mechanical, center-able front sight. The barrel is an AR-Stoner brand 20″-long 1:7″ Government contour chambered in 5.56×45 NATO. Dennis says: “This makes the 7.5-lb weight limit with a few ounces to spare. We’ll see how well it drives soon enough.”
Dennis explains: “The Standard Modern Military (AR) is a category of military-style rifle that shoots the 200-yard, 30- or 50-shot courses alongside the M1 Garands, Springfields, Vintage, and M1 Carbines. This one boasts a Midwest Industries (MI) ultralight Free-float Handguard and a Yankee Hill folding front sight. Any Government contour or thinner profile rifle-length gas tube barrel with a 0.750″ gas block will work.” Colt makes a suitable Government Contour 20″-long, 1:7″-twist barrel, sold by MidwayUSA.
To test the accuracy of his rifle, Dennis fitted a Mantis-X unit on the top of the float tube. The Mantis-X records the movement of the rifle to interpolate shot placements. Dennis reports: “I spent some extra time at the range grabbing a decent zero for my Modern Military rifle. I stuck a Mantis-X on it to record a few shots shooting offhand at the plates at 200 yards. It drives very easily even with no shooting coat or glove.” The Mantis-X is attached just forward of the carry handle, on top of the MI free-float handguard. The Mantis-X works with live fire as well as dry fire. It communicates via BlueTooth to a smartphone App.
Rifle Shoots Well with 77gr Sierra MatchKings
The gun is presently zeroed with 77gr Sierra MatchKing ammunition. Dennis reports his rifle “can easily hold the X-Ring on an SR target for both 100-yard and 200-yard CMP Modern Military Games matches. And it’s fun to shoot!”
CMP Standard Modern Military Rifle (AR Class)
This rifle is built from carefully selected and fitted parts to conform to the CMP’s 7.5-pound weight limit iron-sighted rifle rule. Officially, this is a CMP Standard Modern Military Rifle, Class “A” (AR type).
1. S&W M&P lower receiver
2. White Oak Armament match upper receiver with 1/4×1/4-MOA pinned rear sights
3. AR-Stoner 20″ 1:7″-twist 5.56x45mm NATO Government contour barrel from MidwayUSA*
4. MidWest Industries ultralight free-float handguard with a Titanium barrel nut
5. Yankee Hill Machine folding front sight with a 0.072″ square front pin
6. RRA 2-stage trigger
7. A2 length buttstock
Easy Rifle Build Using Mostly Existing AR Parts, Plus New Barrel and Free-Float Handguard
Dennis was able to put his Modern Military AR together using components he had collected over the years: “Most of these parts were already in my bin of old AR parts available to be recycled. The barrel and free-float handguard were the only new acquisitions.” And with the AR’s modular format, this was an easy build: “Assembly time was about 30 minutes. I’ve done these parts swaps so many times now.”
Key Rules for Standard Modern Military Rifle (AR Type)
Dennis Santiago’s new AR rifle was built as a “Standard U.S. Modern Military Rifle”, Class A (AR Type), as specified in the CMP Games Competition Rules.
5.2.3 Standard U.S. Modern Military Rifles, Class A
Category A Standard Modern Military Rifles must comply with these requirements:
a) Rifles must be based on the M-16 rifle or be based on an AR design;
b) Rifles must be manufactured by a USA manufacturer;
c) Rifles must be equipped with issue-type metallic front and rear sights; rear sights with adjustments finer than one minute of angle are permitted;
d) Total rifle weight, with sights and without sling, may not exceed 7.5 pounds;
e) Rifles may be fitted with a float tube or free-floating handguard. A nonadjustable sling swivel may be attached to the forward end of the handguard; and…
f) The rifle must be chambered for the 5.56x45mm or .223 Remington cartridge.
Also, from Rule 5.2.2:
a) The exterior configuration of the rifle must be the similar to that of the
original military or military-type rifle;
b) The trigger pull may not be less than 4.5 lbs.;
Comments from other Modern Military Rifle Shooters:
“I built a Modern Military [Standard]. It was tough getting below the 7.5-lb [limit]. I had to carve off a bunch of the 20″ barrel diameter but wanted to stay with it for sight radius (over a 16″). I would just as soon shoot that little iron-sighted rifle at 200 yards as my 15-lb Nightforce-scoped Service Rifle. I love that little rifle.” — Kenneth S.
“I’m building one of these that will make 7.5-lb [Standard Modern Military] weight limit, with the long barrel and long sight radius. This has been on my list this winter.” — Tom K.
“We found that turning down a National Match barrel and taking a few inches off of it made a very accurate rifle.” — Jack A.
“My old (complete) A2 upper has been sitting forlorn on a shelf for a couple of years now. Perhaps I need to do a [Standard Modern Military] build of my own.” — Derek D.
Dennis Santiago replied: “Derek — that’s the reason I was attracted to this. I had bought a brand new WOA A2 pin upper receiver to make a new upper then the scope rule was adopted and it was all flat tops. This gives new purpose to the old parts.”
CMP Rules Defining Modern Military Rifles
Standard vs. Unlimited, Class A vs. Class B
There are actually two different classes of Standard Modern Military Rifles, Class A for AR-type rifles and Class B for other military-style rifles, such as the M1A and FN-FAL. Ok, got that? Now, in addition, there is also a second division for UNLIMITED Modern Military Rifles, again with two classes (Class A — AR-type and Class B — other military rifles). These unlimited rifles can have optics, heavier weights, modern-design adjustable-length stocks, and other upgrades. Here is Rule 5.2.2 from the current CMP Games Rifle and Pistol Competition Rules:
The prone position demonstrated by two talented Service Rifle shooters. At top is SFC Brandon Green, multi-time High Power National Champion. Below is Tony Chow, a gifted match shooter. NOTE: Current Service Rifle rules allow the use of optics up to 4.5X.
Jay Christopherson, 2024 and 2020 Southwest Nationals F-Open Champion, is one of the nation’s best F-Class shooters. When shooting F-Class, Jay uses a SEB Mini front rest and a large rear sandbag to support his big 22-lb F-Open rifle. Though he loves F-Class, Jay has also been interested in Service Rifle competition where no external supports are allowed. You hold the rifle with your arms and a sling. Some Service Rifle competitions involve three position (Standing, kneeling/sitting, and prone), while others are prone only. Even in the prone position, the sling is a vital accessory.
Jay dramatically improved his Service Rifle “hard-holding” technique by enlisting the help of Emil Praslick III, former U.S. Army Marksmanship Unit (USAMU) rifle coach. Emil’s guidance and advice resulted in an immediate increase in Jay’s scores on target, as recorded by his ShotMarker electronic target system. Jay noted: “These targets show the difference between hacking it on your own, and spending an hour with someone who knows what they are doing and can tell you that you are doing it wrong.” These targets show Jay’s “before and after” Service Rifle results shooting slung up prone at 600 yards:
Service Rifle, Prone with Sling at 600 Yards
Here is Jay’s target BEFORE training with Emil Praslick — a 194-3X with lots of vertical.
And here is Jay’s improved target AFTER putting Praslick’s advice to work — impressive 199-8X with significantly less vertical.
You can see on this second target much improved vertical. All 20 shots were in a vertical range much smaller than the vertical height of the 10-Ring. Had shot 16 not gone wide left, this would have been a 200. Shot 16 was OUT of the 10-Ring to the left, but note that vertically it has almost perfect elevation.
Jay stated: “I was pretty amazed at not only the difference on the target, but how much difference the changes Emil suggested made to how my hold felt. The entire feel was different and a ton less stress in my neck and arms compared to what I was feeling before. I was actually feeling pretty good about that 194 yesterday, because I hadn’t slung up in two years and that was my highest score (by one point) after doing some load fixing. But having someone explain what you are doing wrong and why makes a world of difference.

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 600-yard target has an X-Ring 6 inches (1 MOA) across, while the 10-Ring spans 12 inches (2 MOA).
The following article is about reloading for NRA/CMP Highpower Rifle competition and is geared toward competitors shooting the AR15 Service Rifle. In Highpower Rifle competition, shooters fire in four stages: Standing slow-fire at 200 yards, Sitting rapid-fire at 200 yards, Prone rapid-fire at 300 yards, and Prone slow-fire at 600 yards. Competitors use a sling for support in all positions but standing. A typical AR15 Service Rifle sports a 20″ free-floated barrel and a 4.5-pound trigger. Service Rifle scopes are limited to maximum power of 4.5X.
Thoughts on Loading for Service Rifles, Particularly for 600 Yards
by Danny Arnold, Team CMP Article originally published in CMP Shooting News
Before we get started, I want to stress that all of the information that follows is geared toward the .223/5.56 Service Rifle. That doesn’t mean that there’s nothing here for anyone else, but the .223/5.56 Service Rifle platform is where I’ve spent the majority of my time, so here we go.
There is only one “Perfect” 600–yard load for my rifle, True or False? This example is more anecdotal than scientific, but it provides some food for thought….
Team CMP spent the early part of March competing in the Orange Blossom Regional. As soon as we got on the range, Sara Rozanski (Team CMP member) started having problems with her 600-yard ammunition. Nearly 1/3 of her cases were exiting the chamber minus the primers. I offered to swap my ammunition for hers, suspecting that my Wylde chamber would be more forgiving than her CLE chamber — a solution that seemed to solve the problem. At least neither of us was blowing primers!
Sara’s ammunition was a factory load using a well-known 80+ grain bullet with an unknown primer and powder, using brass from a respected manufacturer. My load was a different brand of 80-grain bullet, with my choice of powder and primer, all in brass made by someone else. Given the color of the primers, the only thing that our ammunition could possibly have had in common was the brand of powder… maybe. So, how did we shoot?
Sara and I shot the two-person team together and the entire 2,400 Aggregate, although on different relays. Sara’s combined 600-yard score was 780-28X (97.5%). Mine was a 783-24X (97.87%). Our scores were never more than two points apart on any of the four days. Keep in mind that we were using each other’s ammunition the entire time.
So, we had different barrels, chambers and ammunition, but similar results. That goes back to the idea that a good load will perform similarly if fired in a good barrel.
Are We Too Focused on Ballistic Coefficients (BCs)?
The revailing wisdom has always trended toward loading the highest-BC bullet we could find and pushing it as fast as possible. Back in the early ’90s when I got started with the AR15, the 80-grain Sierra was state of the art. Actually, I picked up all of my Leg points with it, although today it looks a bit dated — kinda like me.
So, the question I’ll pose is this: Would you rather shoot a high-BC bullet that groups 3/4-MOA (minute of angle) or a lower-BC bullet that groups into one-half-MOA traveling 50 feet-per-second faster? The reason that I posed this question is a situation I found myself in a decade ago. Our coach decided that he wanted us to pair-fire some 600-yard for practice. Unfortunately, I hadn’t gotten the memo and all that I had available was my normal short-line ammunition, loaded with a 77-grain bullet. The shooter I was paired with was using a higher-BC bullet than I was, but in the end, we both shot 198s.
Admittedly, using 77-grainers meant that coach had to work a little harder to keep us together on target, but it was a teaching moment for me. I knew that my upper shot 77s better than the available bullets in the 80-grain range, so I cranked out a windage table for the 77-grain bullet at 600 yards and shot those for the rest of the season. After all, the wind blows ALL bullets around. It’s just a matter of knowing what YOUR bullet is doing.
With the shortages that we’re experiencing right now, a lighter bullet may be all that you have available for the 2021 season. That doesn’t mean that you’re disadvantaged though.

Loading High-BC Bullets
In the past decade, several bullets have appeared that weigh 80-grains or more. One thing that many of them have in common is a very sharp nose profile, whether metal or polymer. The question is: Are you using the right seating stem?
The jacket material in the bullet’s nose is very thin. If you section a bullet, you’ll find that there is a surprising amount of air space in the nose. If you’re using older seating dies, your seating stem may be contacting the bullet nose too close to the tip, where the jacket is the both thinnest and is unsupported by the lead core. This can manifest itself either as a deformation at the very tip of the bullet or as a circular dent around the bullet nose that you can see and feel with your thumbnail. I think we can all agree that denting a bullet is usually considered a bad thing.
One company goes so far as to recommend their proprietary seating stem for use with their high-BC bullets. Other companies leave it up to you to find a seating stem that will allow the bullet nose to go deeper into the seating stem, moving the contact point further down the bullet where the jacket is thicker and supported by the core material.
Seating Depth and Bullet Preferences
Some bullets don’t mind some “jump” into the lands, but some really do. Unfortunately, manufacturers don’t tell you much about that. Your chamber configuration (Wylde, CLE, or some hybrid of the two) and the bullet that you choose will determine your optimal seating depth. Long and short of it, a quality measuring tool to determine seating depth is a necessity these days. Keep in mind that if you’re doing this with a brand new barrel, the throat is likely going to change slightly in the first 200 rounds and may need to be re-measured. Actually, since all of your short range ammunition has to be loaded to magazine length, you’re probably better off developing your short range loads before starting on long range load development. That gives the throat a chance to wear in a bit on a new barrel.
Brass Prep — Why It Is Important
When match-grade AR15s first arrived on the scene, it was amazing how little it took to get them to shoot well. Other than making sure that I had brass from the same lot and running it through a set of match-grade dies, I did nothing. Of course, we were also using a post front sight. Was the occasional bad shot me, the rifle, the load or just an archaic sighting system?
Transitioning to optics has caused me to reconsider how and what I do in my reloading process: That, and having some extra time on my hands to experiment.
A little (or a lot) of time spent with a neck turning tool, a primer-pocket uniformer and a flash-hole reamer will quickly show you how consistent brass is by manufacturer and even by individual lot. That exercise also makes the prices charged for high-quality brass seem ridiculously cheap. That doesn’t mean that I advocate neck-turning or other uniforming practices, nor do I advocate spending scandalous amounts of money on long-range brass. However, our sport is about consistency. The consistency of your brass is a matter of choice, whether you choose to simply segregate cases by weight (cheap option), neck turn (labor intensive) or open your wallet a little wider for premium brass.
Weighing Charges vs. Throwing with Powder Measure
To measure or weigh? For a long time, I used a powder measure to throw all of my 600-yard loads. The powder I was using metered well, and the results downrange didn’t justify the extra time spent with a scale. That was in the day of iron sights though. Nowadays, I’m throwing my charges and trickling up to the desired weight as measured on a scale that weighs to a 100th of a grain.
To quantify the difference between individually weighing each charge versus throwing charges with a powder measure, I weighed six kernels of powder that I trickled into the pan and then dumped them into the hopper. Going through that process 10 times, I came up with an average weight of .08 grains for six kernels. Next, I threw 50 charges for weighing using my powder measure. If I felt the measure hanging up as it cut kernels, I put the charge back into the hopper without weighing it.
That’s six kernels of powder sitting in the pan — average weight .08 grains.
Those 50 smoothly-thrown charges varied .26 grains from lowest to highest, with the majority varying no more than .16 grains from highest to lowest. If the desired weight was exactly in the middle, at worst you’d be .13 grains (9-10 kernels) low or high, with the majority being off no more than .08 grains (6 kernels) above or below the desired charge weight. Is that enough to send a shot outside the 2-MOA 10-Ring? Probably not.
Has more consistent brass and weighing charges to one-hundredth (0.01) of a grain added up to higher scores? Honestly, this question is hard to answer. Looking at the results on paper at 200 yards, using a powder that meters well combined with a consistent touch on the loading lever doesn’t appear measurably different than meticulously weighing each and every powder charge. Looking back over my 600-yard plots however, I can see a trend toward a group that is closer to X-Ring height.
Since the bullseye is widest at the center, shooting groups that are the height of the X-ring gives you more room for error when the wind is blowing. That can translate into higher 600-yard scores.
How You Load Your Ammunition vs. How You Load Your Rifle
The loading/chambering cycle of the AR-15 is, in a word, violent. You have a relatively heavy bolt and carrier assembly under power of a stout buffer spring slamming forward to chamber each round of ammunition. By design, those rounds were supposed to be held securely by the magazine feed lips until the bolt stripped them off the follower. Obviously, due to their overall length, 600-yard loads can’t be chambered that way. Although the barrel extension is funnel-shaped, it’s also got a lot of “teeth” ringing the inside of it (see below).
Whether you’re using a standard magazine or a single-round loading device (SLED), dropping a round in the loading port and releasing the bolt is an act of faith in that you’re trusting the bullet to arrive in the chamber undamaged.
Ask yourself, how many times have you seen someone drop a round on the follower, press the bolt release and watch as the bolt jammed on a cockeyed round? If that happens once every 100 tries, how many times did the bolt close on a scratched, dented, or misaligned bullet? Could that be the cause of the occasional errant shot?
My technique is to drop each round on top of the SLED and then push it slightly forward with my finger, partially chambering it before releasing the bolt. Admittedly, some people may be unable to do this due to body configuration or left-handedness, but why go to all the trouble of loading “perfect” ammunition and then damage it on the way into the chamber?
Now that we’ve covered bullets, brass, and assorted errata we can move on to discussing loads for 600 Yards…
The NRA Highpower 600-yard target has a 6-inch (1 MOA) X-Ring, and a 12-inch (2 MOA) 10-Ring.
Load Development for 600 Yards
Finding a load for 600 yards is a lot like finding a load for short range. Once I decide on a bullet, powder, primer, velocity range and a measured guesstimate of seating depth, I load 10 rounds of each test load, increasing in 0.2 (2/10) grain increments. I test them from the prone position at 200 yards. Ideally, I want to see two loads that are 0.2 (2/10) of a grain apart that shoot almost identical groups. The load that I choose will fall in between the two best shooting loads that I tested. If the first load is XX.2 grains and the second is XX.4 grains, my chosen load will be XX.3 grains.
Why develop loads in 0.2-grain (tenths) increments if I have a scale that measures in 0.01-grain (hundredths) increments? Or, why not test in 0.1-grain increments?
For me, working in 0.2-grain increments gets me to the results quicker. Also, there is a difference between accuracy and consistency in this scenario. Developing loads in 0.2-grain increments gets me to an accurate load. Producing that load using a scale that accurately measures to .01-grain insures a consistent load, assuming that I do my part.
Once I’ve settled on a load, it’s time to play with seating depth, if I choose to. If I’m lucky and the groups are acceptable as-is, I won’t do anything. If I think there’s room for improvement, I’ll experiment a little. Depending on the bullet, changing the seating depth by a couple of thousandths one way or the other may change the group size. During this phase of testing, it’s a good idea to chamber a round and see if the entire round will then extract. If you leave a bullet stuck in the throat, your rounds are too long. Finding that out at a match can ruin an otherwise good day.

Another thing to keep in mind is that your barrel is not static. Every round fired has an effect on the throat, vaporizing and scouring away metal until the distance the bullet travels before meeting the rifling measurably increases. If you have chosen a bullet that shoots best when close to the lands, you’ll need to periodically re-measure and possibly change your bullet seating depth to maintain that optimal relationship.
The Elephant in the Room — User Skill Level
There’s really not a delicate way to put this, so I won’t try. There’s little point in spending time and effort developing a load that shoots into half-MOA off the bench if you’re only capable of shooting 2 MOA using a sling right now.
That doesn’t mean that there’s no hope. On the contrary, it just means that your time and effort is better spent practicing with some good short-range ammunition on reduced targets at a 100 or 200-yard range. At that distance, wind is not a factor and your technique can be improved more quickly so you’re in a position to benefit from that ½ MOA ammunition.

Berger’s James Fox won the 2023 California Regional High Power Service Rifle Championship shooting Berger factory ammunition and 80.5gr bullets. Fox had a Grand Aggregate score of 1282-48X. Notably, at the closer ranges, Fox shot Berger factory-loaded .223 Rem 77gr OTM ammunition in his AR-platform rifle. For the 600-yard targets, Fox shot ammo loaded with Berger 80.5gr Fullbore bullets. Fox noted: “The Berger 80.5 Grain Fullbore bullets are truly the ‘easy button’ for Service Rifle, because they seem to just shoot in any barrel I have[.]”
The 2023 California Regional Service Rifle High Power Championship was hosted by the Coalinga (CA) Rifle Club on April 1st and 2nd, 2023. With two days of shooting, Fox finished in first on Day One with a score of 792-33X, and first again on Day Two with a 490-15X. In High Power Service Rifle, competitors test their skill in four stages: 200yd Slow-fire Standing, 200yd Rapid-fire Sitting (or kneeling), 300yd Rapid Prone, and 600yd Slow-fire Prone.
With the vast amount of rain California has received in 2023, the Coalinga Range was lush and green. The shooting conditions were also quite good at this April match, with minimal mirage, and mostly consistent winds, making for fairly “easy” shooting and high scores. Competitor Greg Brown noted: “The weather conditions were very pleasant and the winds mild this year. This wind was not a factor for off-hand which helped everyone to generally good scores at the 200-yard line. The winds were somewhat swirly for 300-yard Rapid Fire stage both days and cost some points lost. Conditions for the 600-yard stage looked benign, but tricky enough to prevent any perfect scores, but several 199s were fired on Saturday.”

Berger Ammo and Bullets Used by James Fox
“The California Regional Service Rifle Championship was the start to my 2023 shooting season. It was 23 years since the last time I shot at the Coalinga Rifle Club, which both times have resulted in very favorable outcomes for me”, stated Fox. “The first time in 2000 I earned my last Leg Points to become a CMP Distinguished Rifleman, and this year winning the Championship for the first time. During the two-day Aggregate match, I found some early success in the Rapid-fire Sitting stage at 200 yards, where I shot a sub 1-MOA group using Berger’s .223 Remington 77gr OTM ammunition. And later in the day at 600 yards, I fired Berger 80.5gr Fullbore bullets as they held great elevation allowing me to keep rounds in the middle, despite the wind conditions. The Berger 80.5gr Fullbore bullets are truly the ‘easy button’ for Service Rifle, because they seem to just shoot in any barrel I have, with a wide range of powder charges, Vihtavuori N140 seemingly being the best.” Fox will compete next month at the CMP Eastern Games.
Abundant Grass After Much Rain Attracted Cattle to the Range
Greg Brown noted that there were some special challenges at this match — grazing cattle: “The Coalinga Range was at its most scenic this early April time with deep green hills and the grazing yearling steers getting fatter by the hour. Several times the cattle grazed too lose and the shooters turned cowboys had to wrangle them safely off the range.”

Each summer for the past 100 years, the nation’s top Service Rifle Teams have competed in National Trophy Infantry Team (NTIT) Match at Camp Perry, Ohio. In this match, known informally as the “Rattle Battle”, six-member teams shoot at 200, 300, 500 and 600 yards with time limits — 384 rounds total. To win this match, the six shooters must work like a finely-tuned machine. This is a popular match with spectators as there is plenty of action in a short time span.
The National Trophy Infantry Team Match (NTIT) was first fired in 1922. Only four civilian teams have ever won the prestigious Infantry Trophy that goes to the winner of this match. The first civilian team to win this honor (we are told) was the Massachusetts Team in 1929 followed by a Nebraska Civilian Team in 1930. Seventy-nine years later, in 2009, the California Grizzlies Junior Team won the Infantry Trophy.
The Infantry Trophy Team Match is a unique event where scoring is based on how many hits six-person teams, which begin the match with 384 rounds of ammunition, can score on banks of eight silhouette targets at distances of 600, 500, 300 and 200 yards during 50-second firing periods. The NTIT is sometimes called the “Rattle Battle” because it requires firing, moving to the next firing point with all gear in tow. The match emphasizes extremely fast, accurate fire and good communication among teammates. CLICK HERE for more information.
This video shows the winning 2011 NTIT team at Camp Perry. Six USAMU shooters started with a combined load of 384 rounds to be fired at 8 targets from 600 and 500 yards prone, then 300 yards seated, and finally 200 yards standing.
For the past two years (2021 and 2022) the USAMU-Greenwood Team has won the title with a 1431 score in 2021 and 1344 in 2021. The record team score for this match is 1466, set by the USAMU-Remily Team in 1996. For more information about this great team event, read Unraveling the Mystery of the Rattle Battle on the Shooting Sports USA website.
The National Trophy Infantry Team Match (NTIT) was first fired in 1922 and has been part of the the CMP’s annual National Rifle Matches at Camp Perry. The NTIT is called the “Rattle Battle” because it emphasizes extremely fast, accurate fire.
Our friend Grant U., who runs the Precision Shooting Journal on Facebook, says the NTIT is a special match, a real “crowd-pleaser: “The National Trophy Infantry Team Match (Rattle Battle)… was always one of my favorite team events. It takes a hell of a lot more planning, practice, and precision than one might expect. You get one shot at it and the entire team had better be running on all cylinders because there are no alibis. Each team of six shooters is allocated 384 rounds and when the teams fire at 600 and 500 yards, it sounds like a war.”

BONUS: 20 Marksmanship Articles from USAMU Experts
USAMU shooters and coaches have written an excellent series of articles on highpower and service rifle shooting. Many of these originally appeared in The First Shot, the CMP’s on-line magazine. Here are twenty notable USAMU expert articles:
The prone position demonstrated by two talented Service Rifle shooters. At top is SFC Brandon Green, multi-time High Power National Champion. Below is Tony Chow, a gifted match shooter. NOTE: Current Service Rifle rules allow the use of optics up to 4.5X.
Jay Christopherson, 2020 Southwest Nationals F-Open Champion, is one of the nation’s best F-Class shooters. When shooting F-Class, Jay uses a SEB Mini front rest and a large rear sandbag to support his big 22-lb F-Open rifle. Though he loves F-Class, Jay was also interested in Service Rifle competition where no external supports are allowed. You hold the rifle with your arms and a sling. Some Service Rifle competitions involve three position (Standing, kneeling/sitting, and prone), while others are prone only. Even in the prone position, the sling is a vital accessory.
Jay dramatically improved his Service Rifle “hard-holding” technique by enlisting the help of Emil Praslick III, former U.S. Army Marksmanship Unit (USAMU) rifle coach. Emil’s guidance and advice resulted in an immediate increase in Jay’s scores on target, as recorded by his ShotMarker electronic target system. Jay noted: “These targets show the difference between hacking it on your own, and spending an hour with someone who knows what they are doing and can tell you that you are doing it wrong.” These targets show Jay’s “before and after” Service Rifle results shooting slung up prone at 600 yards:
Service Rifle, Prone with Sling at 600 Yards
Here is Jay’s target BEFORE training with Emil Praslick — a 194-3X with lots of vertical.
And here is Jay’s improved target AFTER putting Praslick’s advice to work — impressive 199-8X with significantly less vertical.
You can see on this second target much improved vertical. All 20 shots were in a vertical range much smaller than the vertical height of the 10-Ring. Had shot 16 not gone wide left, this would have been a 200. Shot 16 was OUT of the 10-Ring to the left, but note that vertically it has almost perfect elevation.
Jay stated: “I was pretty amazed at not only the difference on the target, but how much difference the changes Emil suggested made to how my hold felt. The entire feel was different and a ton less stress in my neck and arms compared to what I was feeling before. I was actually feeling pretty good about that 194 yesterday, because I hadn’t slung up in two years and that was my highest score (by one point) after doing some load fixing. But having someone explain what you are doing wrong and why makes a world of difference.

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.
