PRS Gas Gun Match — Winning Hardware and Match Strategies

PRS Gas Gun Match CORE Florida

Shooting Sports USA just released an excellent, in-depth article about the first-ever PRS Gas Gun Match. If you enjoy tactical-style shooting, or have an interest in modern semi-auto rifles, we strongly recommend you read this match report by SSUSA Editor John Parker. Offered in a magazine-style format, this SSUSA feature includes explanations of the rules and tactics for these matches, along with interviews with top competitors, including match winner SSG Tyler Payne of the USAMU.

Payne dominated the match, finishing 200 points ahead of the next competitor. Payne competed in Open Class shooting a JP Enterprises LRP-07 chambered in 6mm Creedmoor, running Berger 105gr 6mm Hybrids at 2975 fps. He used a Vortex Razor HD 4.5-27x56mm scope. With its 6X zoom ratio, this optic allowed SSG Payne to switch from a wide field of view to high magnification as the stage demanded. With targets out to 800 yards, having 27X on tap was useful.

There are three divisions in PRS Gas Gun Matches: Tactical Light (.223 Rem/5.56), Tactical Heavy (.308 Win), and Open. At this match, about 65% of shooters competed in Tac Light. Match Director Ryan Castle said: “The remaining 35% was split pretty evenly between Open and Tactical Heavy.”

Open Class Caliber Choices
“For Ammo in Open Class, 6mm and 6.5mm Creedmoor were popular — overall winner SSG Tyler Payne won using a rifle chambered in 6mm Creedmoor”. — John Parker, SSUSA

Gas Gun Match Loads — Short Range vs. Long Range
“The .223/5.56 [Tactical Light] guns had some lag time waiting on shot impacts. I believe the long-term solution may be to find a light and fast load for closer stages for near-instant reaction time and use a heavy load for the long shots to see splash and get the target to move a little more.” — Sean Murphy, Nightforce

Interview with Match Winner Tyler PaynePRS Gas Gun Match CORE Florida
SSG Tyler Payne told SSUSA: “This match has a lot of similarities to 3-Gun, which I’ve been shooting for 11 years now. With targets out to 800 yards, limited rounds and 30-second penalties, the match gave you the opportunity to go as fast as you wanted but really forced you to be accurate. Training for PRS has given me enough discipline to make my shots count and 3-Gun has taught me how to be efficient. Those two things helped me excel at this match. Having to slow down with a gas gun and make my shot count was very foreign to me. Usually at matches with a gas gun, you get as many shots as you want to take, so having to slow down was difficult.”

“If I had any pointers for someone wanting to try this type of match it would be to get out and confirm your data as far as you can. Don’t trust your ballistic Apps. Other than that, ask questions, watch the experienced shooters and have fun”.

PRS Gas Gun Series Rules

For the new PRS “Gasser” Competition, the PRS developed rules on gun types, scoring, match timing, penalties, safety and other key topics. CLICK HERE for Full PRS Gas Gun Series Rules.

Open Division: The Open Division rifles will not exceed a caliber of .30 or a velocity of 3,200 fps. With this and other divisions, Match Officials may request at any point during a match that a competitor fire their rifle through chronograph..

Tactical Light Division: Tactical Light Division rifles are restricted to 5.56 NATO/.223 Remington calibers only. Bullet weight cannot exceed 77 grains and muzzle velocity cannot exceed 3,000 fps.

Tactical Heavy Division: This class is restricted to .308 Win (7.62×51) gas guns. Most will be AR-10 platform rifles. Bullet weight cannot exceed 178 grains and muzzle velocity cannot exceed 2,800 fps.

Scoring and Penalties
The Gas Gun Series utilizes a time plus penalty-based scoring system for all match scoring. This means the score is the shooter’s total combined time on all stages plus any penalties accrued.

Penalties are as follows:
30 seconds for any rifle targets not engaged or neutralized.
15 seconds for any pistol targets not engaged or neutralized.
15 seconds for hitting a “No Shoot” target.
No more than 50% of the stages at a match can utilize an unlimited round count. At least 25% of the targets in Gas Gun Series match must be 2 MOA or smaller. Max distance is 800 yards.

Precision Handloading for Pistols — Tips from the USAMU

USAMU Service Pistol Handgun Tip Advice Reloading

Each Wednesday the USAMU offers tips for handloaders on the USAMU Facebook page. This article from the “Handloading Hump-Day” archives should interest pistol competitors, an any shooter who enjoys getting the best possible accuracy from their fine pistols. In this article, the USAMU’s experts share key tips that can help optimize your pistol ammo. Follow this tips to produce more consistent ammo, that can shoot higher scores.

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.

USAMU Service Pistol Handgun Tip Advice ReloadingUse 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, for the “long line” (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.

USAMU Service Pistol Handgun Tip Advice Reloading

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!

Chronograph Testing — Tips from the USAMU

USAMU Marksmanship Unit Velocity Chronograph Testing Sample Sizes

Each Wednesday, the U.S. Army Marksmanship Unit publishes a reloading “how-to” article on the USAMU Facebook page. This past week’s “Handloading Hump Day” article, the latest in a 7-part series, relates to chronograph testing and statistical samples. We highly recommend you read this article, which offers some important tips that can benefit any hand-loader. Visit the USAMU Facebook page next Wednesday for the next installment.

Chronograph Testing — Set-Up, Sample Sizes, and Velocity Factors

Initial Chronograph Setup
A chronograph is an instrument designed to measure bullet velocity. Typically, the bullet casts a shadow as it passes over two electronic sensors placed a given distance apart. The first screen is the “start” screen, and it triggers an internal, high-speed counter. As the bullet passes the second, or “stop” screen, the counter is stopped. Then, appropriate math of time vs. distance traveled reveals the bullet’s velocity. Most home chronographs use either 2- or 4-foot spacing between sensors. Longer spacing can add some accuracy to the system, but with high-quality chronographs, 4-foot spacing is certainly adequate.

Laboratory chronographs usually have six feet or more between sensors. Depending upon the make and model of ones chronograph, it should come with instructions on how far the “start” screen should be placed from one’s muzzle. Other details include adequate light (indoors or outdoors), light diffusers over the sensors as needed, and protecting the start screen from blast and debris such as shotgun wads, etc. When assembling a sky-screen system, the spacing between sensors must be extremely accurate to allow correct velocity readings.

Statistics: Group Sizes, Distances and Sample Sizes
How many groups should we fire, and how many shots per group? These questions are matters of judgment, to a degree. First, to best assess how ones ammunition will perform in competition, it should be test-fired at the actual distance for which it will be used. [That means] 600-yard or 1000-yard ammo should be tested at 600 and 1000 yards, respectively, if possible. It is possible to work up very accurate ammunition at 100 or 200 yards that does not perform well as ranges increase. Sometimes, a change in powder type can correct this and produce a load that really shines at longer range.

The number of shots fired per group should be realistic for the course of fire. That is, if one will be firing 10-shot strings in competition then final accuracy testing, at least, should involve 10-shot strings. These will reflect the rifles’ true capability. Knowing this will help the shooter better decide in competition whether a shot requires a sight adjustment, or if it merely struck within the normal accuracy radius of his rifle.

How many groups are needed for a valid test? Here, much depends on the precision with which one can gather the accuracy data. If shooting from a machine rest in good weather conditions, two or three 10-shot groups at full distance may be very adequate. If it’s windy, the rifle or ammunition are marginal, or the shooter is not confident in his ability to consistently fire every shot accurately, then a few more groups may give a better picture of the rifle’s true average.

Mental Game — Thinking Your Way to Success

praslick emil usamu mental training game marksmanship

SFC Emil Praslick III is now retired from the U.S. Army, but he left a great legacy as one of the USAMU’s greatest coaches and team leaders. A highly-respected wind expert, Praslick also was known for his ability to help his shooters master the “mental game”, which is so important at the highest levels of competition. Here is an article from the CMP Archives in which Praslick explains how to focus your mind to achieve greater success.

Thinking Your Way to Success by SFC Emil Praslick III (Ret.)
Why does it seem that the same small group of shooters wins the majority of the matches? Within the Army Marksmanship Unit’s Service Rifle Team, the same effect applies. On a team filled with uncommonly talented shooters, the same two or three are consistently at the top of the final results bulletin. What is the difference among shooters who are technically equal? Confidence. A confident shooter is free to execute his shots without the fear of failure, i.e. shooting a poor shot.

Negative thoughts (can’t, won’t be able to, etc.) will destroy a skilled performance. The mind’s focus will not be on executing the task, but on projecting fear and self-doubt. Fear is the enemy, confidence is the cure.

How does a shooter on the eve of an important match (the President’s or NTI, for example) attain the confidence needed to perform up to his potential? A pre-competition mental plan can assist in acquiring that positive mental state. The plan can be broken down into a few phases.

Build a feeling of preparedness. Developing and executing a plan to organize your equipment and pre-match routine will aid you in feeling prepared on match day.

Avoid negative and stressful thoughts. Focusing on “winning” the match or shooting for a specific score (like making the “cut” or making the President’s 100) can cause undue stress. Good shooters focus on aspects that are within their control: their sight picture, their sight alignment, their position. Each shot should be treated as an individual event.

Train stage-specific tasks during your practice sessions. Instead of shooting matches or practice matches only, include some drills that focus on your problem areas. Training in this manner will assist your level of confidence.

As part of your pre-match routine, imagine yourself shooting perfect shots. Visualize getting into the perfect position, acquiring a perfect sight picture, and perfect trigger control.

Let a feeling of calm and well-being wash over you. Spend a few minutes alone thinking positive thoughts. Many shooters use their favorite music to help build the mood.

Once you develop your pre-competition mental plan, stick with it. Through your training you will develop the physical skills to shoot higher scores. The confidence you will need to apply them in match conditions will grow as you develop into a complete shooter; both physically and mentally.

Team Match Day at the Berger Southwest Nationals

Team competition Berger Southwest Nationals SWN team match

Thursday was TEAM DAY at the Berger Southwest Nationals (SWN). In the Sling, F-TR, and F-Open classes, dozens of 4-person teams shot under coaches at 800, 900, and 1000 yards. The key difference between the team game and individual competition is that (for the most part) shooters function as trigger pullers only. Wind and elevation calls are typically made by the coaches, who sometimes even dial clicks for the shooters. In the above photo Bryan Litz is just about to click his shooter’s elevation turret.

This year the Scottish Thistle Team won the Sling division, lead by a strong 449-27X performance by Angus McLeod. The Hayes Rays of Sunshine Team finished second, six points back. In the highly competitive F-TR class, North by Southwest took the team title, with Da Bulls in second.

In the F-Open class, the Cluster Ducks (clever name) took the win, edging out second place The Longshots by a single point. Third in F-Open was Tex-Mex #1. Kudos to AccurateShooter’s own Jay Christopherson, our site systems manager, who lead 4th Place Team Lapua/Brux with a strong 448-25X. Jay keeps our servers running smoothly — and he’s a great shooter in his own right.

Here’s Team Krieger (foreground) getting ready on the 1000-yard line.

In fact, the second-place Longshots also broke the previous 1786-104X record, set by Team Grizzly in 2014. Because the Cluster Ducks edged The Longshots by one point the Ducks will go down in the record books. But both teams can rightfully say they broke the then-current 1786-point F-Open record. Well done shooters!

Cartridge “Efficiency” — Factors to Consider from the USAMU

USAMU Handloading Guide Facebook cartridge efficiency

Efficient cartridges make excellent use of their available powder and case/bore capacity. They yield good ballistic performance with relatively little recoil and throat erosion.

USAMU Handloading Guide Facebook cartridge efficiency

Cartridge Efficiency: A Primer (pun intended!) by USAMU Staff

Each week, the U.S. Army Marksmanship Unit (USAMU) publishes a reloading article on its Facebook Page. In this week’s article, the USAMU discusses cartridge case efficiency and its benefits. While this is oriented primarily toward NRA High Power Rifle and Long Range (1000-yard) competition, these factors also apply to medium/big game hunters. Assuming one’s rifle and ammunition are accurate, key considerations include ballistic performance (i.e., resistance to wind effects, plus trajectory), recoil, and throat erosion/barrel life.

Efficient cartridges make excellent use of their available powder and case/bore capacity. They yield good ballistic performance with relatively little recoil and throat erosion. A classic example in the author’s experience involved a featherweight 7x57mm hunting/silhouette rifle. When loaded to modern-rifle pressures, just 43-44 grains of powder pushed a 139gr bullet at 2900 fps from its 22” barrel. Recoil in this light rifle was mild; it was very easy to shoot well, and its performance was superb.

An acquaintance chose a “do everything” 7mm Remington Magnum for use on medium game at short ranges. A larger, heavier rifle, it used ~65 grains of powder to achieve ~3200 fps with similar bullets — from its 26″ barrel. Recoil was higher, and he was sensitive to it, which hampered his shooting ability.

Similarly efficient calibers include the 6mm BR [Norma], and others. Today’s highly-efficient calibers, such as 6mm BR and a host of newer developments might use 28-30 grains of powder to launch a 105-107gr match bullet at speeds approaching the .243 Winchester. The .243 Win needs 40-45 grain charges at the same velocity.

Champion-level Long Range shooters need every ballistic edge feasible. They compete at a level where 1″ more or less drift in a wind change could make the difference between winning and losing. Shooters recognized this early on — the then-new .300 H&H Magnum quickly supplanted the .30-06 at the Wimbledon winner’s circle in the early days.

The .300 Winchester Magnum became popular, but its 190-220gr bullets had their work cut out for them once the 6.5-284 and its streamlined 140-142gr bullets arrived on the scene. The 6.5-284 gives superb accuracy and wind performance with about half the recoil of the big .30 magnums – albeit it is a known barrel-burner.

Currently, the 7mm Remington Short Action Ultra-Magnum (aka 7mm RSAUM), is giving stellar accuracy with cutting-edge, ~180 grain bullets, powder charges in the mid-50 grain range and velocities about 2800+ fps in long barrels. Beyond pure efficiency, the RSAUM’s modern, “short and fat” design helps ensure fine accuracy relative to older, longer cartridge designs of similar performance.

Recent design advances are yielding bullets with here-to-fore unheard-of ballistic efficiency; depending on the cartridge, they can make or break ones decision. Ballistic coefficients (“BC” — a numerical expression of a bullet’s ballistic efficiency) are soaring to new heights, and there are many exciting new avenues to explore.

The ideal choice [involves a careful] balancing act between bullet BCs, case capacity, velocity, barrel life, and recoil. But, as with new-car decisions, choosing can be half the fun!

Factors to Consider When Evaluating Cartridges
For competitive shooters… pristine accuracy and ballistic performance in the wind are critical. Flat trajectory benefits the hunter who may shoot at long, unknown distances (nowadays, range-finders help). However, this is of much less importance to competitors firing at known distances.

Recoil is an issue, particularly when one fires long strings during competition, and/or multiple strings in a day. Its effects are cumulative; cartridges with medium/heavy recoil can lead to shooter fatigue, disturbance of the shooting position and lower scores.

For hunters, who may only fire a few shots a year, recoil that does not induce flinching during sight-in, practice and hunting is a deciding factor. Depending on their game and ranges, etc., they may accept more recoil than the high-volume High Power or Long Range competitor.

Likewise, throat erosion/barrel life is important to competitive shooters, who fire thousands of rounds in practice and matches, vs. the medium/big game hunter. A cartridge that performs well ballistically with great accuracy, has long barrel life and low recoil is the competitive shooter’s ideal. For the hunter, other factors may weigh more heavily.

Cartridge Efficiency and Energy — Another Perspective
Lapua staffer Kevin Thomas explains that efficiency can be evaluated in terms of energy:

“Cartridge efficiency is pretty straight forward — energy in vs. energy out. Most modern single-based propellants run around 178-215 ft/lbs of energy per grain. These figures give the energy potential that you’re loading into the rifle. The resulting kinetic energy transferred to the bullet will give you the efficiency of the round. Most cases operate at around 20-25% efficiency. This is just another way to evaluate the potential of a given cartridge. There’s a big difference between this and simply looking at max velocities produced by various cartridges.”

Excellent Video Covers Handgun Fundamentals

Pistol Fundamentals USAMU

If you shoot a pistol, you should watch this video. It covers the key fundamentals of handgun shooting: stance, arm position, grip, sight alignment, and trigger control. This excellent video features USAMU shooter SGT Shane Coley.

Arm/Elbow Position: You should not lock your elbows says SGT Coley: “Because my elbows are slightly bent, it allows the recoil to transfer into my shoulders, down my core, into my legs and to the ground, allowing me to maintain a flat-shooting gun … on multiple targets.”

Grip (Hand Position): SGT Coley explains how to divide the support between both hands: “In terms of grip pressure, I’m applying about 60% to my support hand, and 40% to my strong hand. This is because I need to maintain dexterity with my strong hand to operate the trigger at high rates of speed.”

Trigger Control: The placement of your finger on the trigger blade itself is very important notes Coley: “Putting too much (or not enough) of your finger on the trigger can cause you to pull or push your shots. When you squeeze the trigger, make sure to squeeze it all the way to the rear, in one smooth motion. A quick dry-fire drill to help you with this is to take an empty piece of brass and place it on the front of your slide. Aim at the target, and with the proper trigger control, you should be able to break the shot without the piece of brass falling.”

Pistol Pointers
On the web, you’ll find hundreds of pistol shooting videos — some good, some not helpful at all. In some of those “not helpful” videos the featured shooter has bad habits, or more often than not, he exhibits poor accuracy on target. You won’t find those kinds of shortcomings in this USAMU-sponsored video. SGT Coley doesn’t make foolish mistakes, nor does he exhibit bad habits when shooting. And his accuracy is outstanding. When you look for a pistol trainer — stick to someone like SGT Coley, who has solid fundamentals, the complete skill set, and superior accuracy. A trainer can’t teach a skill that he doesn’t understand himself.

Primer Pocket and Flash Hole Uniforming Basics

Reloading Case Prep Flash Hole Primer Pocket

The U.S. Army Marksmanship Unit (USAMU) has published a series of reloading “how-to” articles on its Facebook Page. This post explains how to uniform primer pockets and remove burrs in flash holes. These brass prep operations can help ensure greater consistency, shot after shot. Visit the USAMU Facebook Page each Wednesday for other, helpful “Handloading Hump-Day” tips.

Primer Pocket and Flash-Hole Conditioning

This week, we’ll address a question that frequently arises: “Do you uniform primer pockets and deburr flash-holes?”

As we tailor our handloading methods to the specific needs of each instance, the answer, not surprisingly, is “occasionally!” Generally, the USAMU Handloading Shop does not uniform primer pockets (PP) or deburr flash holes (FH) of our rifle brass. That’s not to say we’re against it — rather, it reflects the very high volume of ammunition loaded, the fact that very few cases are ever re-loaded for a second firing, and the types of brass we use. However, as a need is perceived, we DO deburr flash holes (of which, more later.)

As to the type cases we use, many thousands of our long-range 5.56x45mm cases come to us from the arsenal with the primer of our choice pre-installed and staked in per their usual practice. Obviously, we could not uniform either FHs or PPs on this live-primed brass. However, after careful sorting, inspection and preparation, we do obtain match-winning results with it. Regular readers have seen photos of some of the tiny 1000-yard test groups we’ve fired with weight-selected domestic brass which had neither Primer Pockets uniformed nor flash holes deburred.

Reloading Case Prep Flash Hole Primer Pocket
Figure 1 shows a fired, deprimed 7.62×51 case with primer residue intact. In Figure 2, the primer pocket has been uniformed to SAAMI specs. Note the shiny finish — evidence of the metal removed to uniform and square the primer pocket.

Shooters who reload their brass several times may decide to uniform PPs and deburr FHs, especially on their “300-yard and beyond” brass. Unlike us, they will be using their cases many times, while the operations are only needed once. Also, most handloaders only process a relatively moderate amount of brass compared to our 20-thousand round lots. Having high quality Long Range (LR) brass helps. Many of the better brass manufacturers form their flash holes so that no burrs are created.

Still, it does pay to inspect even THESE manufacturer’s products, as occasional slips are inevitable. Very rarely, some of these makers will have a significant burr in, say, 1 per 1000 or 2000 cases, and it’s worth catching those. Recently, we began processing a large lot of match brass from a premier manufacturer, and were startled to find that every case had a burr in the FH — something we’d never before seen from this maker. We then broke out the FH deburring tool and went to work.

Reloading Case Prep Flash Hole Primer Pocket

For those who do opt for these procedures, note that various tool models may have adjustable depth-stops. Pay attention to the instructions. Some flash hole deburring tools which enter the case mouth, not the primer pocket, depend on uniform case length for best results.

Does It Really Make a Difference?
It can be difficult to truly verify the contribution to accuracy of these procedures, particularly when firing from the shoulder, in conditions. Members of this staff, as individual rifle competitors, do often perform these operations on their privately-owned LR rifle brass.

One could ascribe this to the old High Power Rifle maxim that “if you think it helps, then it helps”. Another thought is to “leave no stone unturned” in the search for accuracy.

However, an extremely talented World Champion and Olympic Gold/Silver medalist commented on his own handloading (for International competition, which demands VERY fine accuracy). He noted that he did seem to see a decline in accuracy whenever he did not uniform FH’s, deburr FH’s and clean primer pockets before each reloading; however, with the wisdom of decades’ experience, he also remarked that “It could have been that I just wasn’t shooting as well that day.”

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.

USAMU Handloading vertical dispersion ignition rimfire accuracy firing pinIs 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:

USAMU Handloading vertical dispersion ignition rimfire accuracy firing pin

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.

USAMU Handloading vertical dispersion ignition rimfire accuracy firing pin

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
Rem 700 bolt 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!

AR, Garand, M1A — Six Rules for Gas Gun Reloading

Reloading for Service Rifles
SFC Lance Dement as featured in CMP’s First Shot Online.

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 each Wednesday for other, helpful “Handloading Hump-Day” 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.

Reloading for Service Rifles

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!

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.

Six Great Guidebooks for Pistol Shooters

Pistol Marksmanship training book

One of our Forum members asked: “Are there any good books on pistol marksmanship? I’m looking for a book that covers techniques and concepts….” Here are our recommendations — six titles that can make you a better pistol shooter. These books run the gamut from basic handgun training to Olympic-level bullseye shooting.

Pistol Marksmanship training book 1911 race gunGood Guidebooks for Pistol Shooters
There are actually many good books which can help both novice and experienced pistol shooters improve their skills and accuracy. For new pistol shooters, we recommend the NRA Guide to the Basics of Pistol Shooting. This full-color publication is the designated student “textbook” for the NRA Basic Pistol Shooting Course.

Serious competitive pistol shooters should definitely read Pistol Shooters Treasury a compilation of articles from World and National Champions published by Gil Hebard. You could work your way through the ranks with that book alone even though it is very small. It is an excellent resource.

If you’re interested in bullseye shooting, you should get the USAMU’s The Advanced Pistol Marksmanship Manual. This USAMU pistol marksmanship guide has been a trusted resource since the 1960s. Action Shooters should read Practical Shooting: Beyond Fundamentals by Brian Enos, and Ben Stoeger’s new-for-2013 Practical Pistol Book. Brian Enos is a well-known pistol competitor with many titles. Ben Stoeger is a two-time U.S. Practical Pistol shooting champion and a member of the USA Team at the 2011 World Pistol Championships. Last but not least, Julie Golob’s new Shooting book covers pistol marksmanship, along with 3-Gun competition. Julie holds multiple national pistol shooting titles.

Basics of the Prone Position — Building the Position

USAMU Prone First Shot CMP
USAMU Prone First Shot CMP

The First Shot, the CMP’s online magazine, features a well-written article on Prone Shooting Technique by SPC Matthew Sigrist of the U.S. Army Marksmanship Unit (USAMU). The article covers all the major points of gun hold and body position: hand position, elbow position, stock weld, buttstock placement, and sling position/tension.

Keep it Steady — The Elements of a Good Prone Position

Part 1 — Building the Position
By SPC Matthew Sigrist

Imagine the following scenario: You are at the last stage of fire in the National Trophy Individual Match, firing at the 600 yard line in the prone position and every point matters. What should you reflect on as you prepare to shoot this final string? As your eyes cloud from sweat, you realize that all you have to rely on is your experience and knowledge of the fundamentals.

During the National Trophy Individual Match, you will fire 60 percent of your shots from the prone position. This article will address the fundamentals of a good prone position and help you learn the techniques required to be successful in both the slow and rapid-fire stages of National Match competition.

This article will be divided into two parts. In part one, we will discuss the elements of a good prone position. In part two, we will cover the techniques you will in the rapid-fire and slow-fire stages.

The Fundamentals

The fundamentals are the building blocks of a position. Much like the framework of a house, a correct application of the fundamentals ensures a solid and stable structure. Since each person’s position will depend on their particular body build and shape, there is no “perfect position” that applies to everyone. Experience, practice and knowledge of the correct fundamentals will dictate the best position for you.

There are six key elements of any position. The purpose for these six points is to achieve a solid platform that allows for consistent sight alignment using the least amount of muscle tension.

    1. Placement of the Firing Hand (the hand that pulls the trigger)
    The firing hand needs to be placed high on the pistol grip. This high hand position will give you better control of the rifle. Combined with a firm grip there will be a reduced amount of hand movement when pulling the trigger. Wrap your thumb over the three fingers on the pistol grip (excluding the trigger finger). This will help isolate the movement of the trigger finger.

    2. Placement of the Non-firing Hand (the hand supporting the rifle).
    The non-firing hand should grip the handguard or stock in the flat portion of the hand between the thumb and forefinger. The fingers should curl naturally around the stock, but they should not grip it tightly. The position of the hand on the stock will depend on the physical size of the shooter. Generally speaking, taller shooters with longer arms will grip the rifle further out, near the sling swivel, while shorter shooters will need to pull their hand rearward. This is sometimes referred to as “short-stocking” the rifle.

    3. Stock Weld
    Stock weld is the contact that the face makes with the stock. It is important because it directly effects your sight alignment. Consistent head placement will help you achieve consistent sight alignment. The human head weighs an average of 8 to 10 pounds. The full weight of the head must rest on the stock. In doing this you achieve two things, a relaxed neck and reduced recoil because of the pressure of the head.

    4. Placement of the Rifle (the contact that is made in the firing shoulder)
    The rifle butt placement needs to be consistent. If this changes between shots, it effects your sight alignment and the effect of recoil. In the prone position the rifle will sit lower in the shoulder compared to other shooting positions. This allows for a more forward head and a lower position as a whole.

    5. Position of the Sling
    The sling should be high on the arm, above the bicep. This way the sling will have less leverage on the arm so it doesn’t cut off the circulation.


Demonstration of the placement of the firing elbow (left) and non-firing elbows (right).

    6. Placement of both the firing, and non-firing elbows
    A guideline for non-firing elbow placement is that there should be 1 ½’’ to 2’’ gap between your non-firing arm and the rifle’s magazine. (NOTE: this references the AR-15 service rifle) Your arm should be almost straight up and down; this will transfer the weight directly down the arm and not to the side (see picture above). Think of the firing arm as only a kind of kickstand, it doesn’t support weight it only holds the firing hand in position.

Variations of the Prone Position

There are two main variations of the prone position; open/spread legged, and bent-legged. The two types will be discussed below.

Open/Spread Leg Position

Demonstration of the Open/Spread Leg Position.

The first position is the open/spread legged position. This is when the shooter spreads their legs shoulder width or more apart. This allows for a more forward pressure on the sling and elbows. This position requires a tighter sling and solid elbow placement. The rifle should sit tight in the shoulder. With this position, your body will be farther behind the rifle compared to the bent leg position, allowing for minimum disturbance from recoil.

Bent Leg Position

Demonstration of the Bent Leg Position.

The bent leg position is when the shooter bends the firing side leg up towards the firing hand making the knee at a rough 90 degree angle to the body. The non-firing leg will remain straight and inline with the body. This will take pressure off the lungs and heart minimizing the pulse from the chest as well as easing the pressure on the lungs which will allow for easy breathing and control.

Summary

You now know the fundamentals of a good prone position, as well as the two types most commonly used. Extensive dry-firing will reveal which is the best position for you. If possible, have a friend take pictures of you in position. This will enable you to better diagnose and correct your errors. Remember, a position must be both fundamentally sound and comfortable. Practice frequently to learn your new position and to develop the conditioning required to endure long days on the range.

USAMU Advice for Progressive Press Users

Accurateshooter.com USAMU progressive press reloading

Each Wednesday, the U.S. Army Marksmanship Unit (USAMU) publishes a reloading “how-to” article 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.

USAMU Reloading

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.

Fundamentals — Sight Alignment and Trigger Control

Marksmanship Fundamentals iron sights USAMU

This video from the U.S. Army Marksmanship Unit focuses on two key fundamentals of marksmanship: 1) Sight Alignment; and 2) Trigger Squeeze. This video can assist any Service Rifle or metallic sights shooter. The USAMU instructor explains: “You’ve probably heard a lot about fundamentals — Breathe, Relax, Aim, Squeeze… Well that gives a shooter a lot to think about. Here we teach two main firing tasks: 1) align the sights, and 2) squeeze the trigger without moving the rifle. This allows the shooter a much more simplified format.”

The following tips are transcribed from the video:

Task One: Sight Alignment
Sight alignment is the process of putting the tip of the front sight post, the rear aperture, and the shooter’s eyeball all on the same plane. It’s very important to maintain the tip of the front sight post centered in the rear aperture. Just .002″ of deviation can cause a miss at 300 meters. Allow your eye to do its job. While firing, the focus should remain on the tip of the front sight.

Task Two: Trigger Control
Your second firing task is [to] fire the rifle without moving it. This is done through proper trigger control. You’ve probably heard a lot of words about trigger control — “surprise break”, “snatch”, “pull”, “squeeze”… well we teach one thing here: “smooth”. No matter the speed at which I engage the trigger, it’s always going to be smooth. Imagine trying to pull the trigger straight through the rear of the buttstock, holding it to the rear while the gun recoils. It’s important to constantly engage the trigger, never letting your trigger finger disengage from the trigger while firing. This is achieved through natural trigger finger placement.

Precision Reloading for Handguns — Smart Tips from the USAMU

USAMU Service Pistol Handgun Tip Advice Reloading

The U.S. Army Marksmanship Unit (USAMU) fields pistol teams as well as rifle and shotgun competition squads. Consequently the USAMU’s Reloading Shop loads tens of thousands of pistol rounds every year. In this article, the USAMU’s handgun experts talk about reloading for handguns — with smart tips on how to achieve superior accuracy with 100% reliability. If you load for pistols, take the time to read this article, which offers important insights on COAL, primers, crimps and more.

USAMU Service Pistol Handgun Tip Advice Reloading

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.

USAMU Service Pistol Handgun Tip Advice ReloadingUse 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, for the “long line” (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!

Hunting Tip: How to Plot Your Cold Bore Point of Impact

Commonly, hunters won’t have the ability to fire one or two fouling shots before heading out on a hunt. Therefore it’s important that a hunter understands how his rifle shoots with a “cold bore shot”. Both the point of impact (and possibly velocity), may be different with a cold bore than with a barrel that has been warmed and fouled with a series of shots. In this video from the U.S. Army Marksmanship Unit (USAMU), you’ll learn how to determine your cold bore point of impact (POI) for a rifle that just been cleaned, as well as the cold bore POI with a barrel that has already been “fouled in”.

SGT Joe Hein of the USAMU shows how to plot cold bore POI with both a clean bore and a fouled bore. Note that the “cold bore” shot from a fouled barrel was closer to the follow-up shots than the cold bore shot from a clean barrel. This is typical of many factory barrels. SGT Hein provides a simple way to understand your rifle’s cold bore performance. Hein’s advice can keep you from missing that long range shot at that big buck on opening day. A little time spent on the range before that critical first shot will help ensure you have meat in the freezer this season.

Position Shooting Tips for Hunters — How to Stabilize Your Shot

USAMU Michael McPhail position hunting prone kneeling treestand

Team USA Olympian and ISSF World Cup Winner SFC Michael McPhail is one of the world’s best smallbore rifle shooters. He is also an avid hunter, who enjoys harvesting game with centerfire rifles. In this excellent short video from the USAMU, McPhail shows how competition shooting positions can be adapted for hunters. McPhail shows how well-established positions can provide a more stable platform for hunters in the field. That can help ensure a successful hunt. McPhail demonstrates three positions: kneeling, supported prone, and sitting in a tree-stand.

Watch SFC McPhail Demonstrate Positions for Hunters (Good Video):

USAMU Michael McPhail position hunting prone kneeling treestand

McPhail first demonstrates the kneeling position. Michael notes: “I like kneeling. It’s a little bit of an under-utilized position, but it’s almost as stable as prone. It allows you get up off the ground a little bit higher to [compensate for] vegetation. For kneeling start by taking your non-dominant foot and put that towards the target, while at the same time dropping down to a knee on the dominant leg. At the same time … wrap the sling around wrist and fore-arm, lean slightly into the target and take the shot.”

USAMU Michael McPhail position hunting prone kneeling treestand

McPhail shows a nice “field expedient” use of your backpack. He shows how the basic prone position can be adapted, using the pack as a front rifle support. McPhail recommends pulling your dominant (strongside) leg forward, bent at the knee. According to Michael, this takes pressure off the abdomen, helps minimizes heart beat effects, and helps with breathing.

USAMU Michael McPhail position hunting prone kneeling treestand

Last but not least, McPhail shows some clever treestand tricks. McPhail recommends a position with your weakside leg pulled up and firmly braced on the front rail of the treestand. You can then rest your support arm on your leg. (That would be the left arm for a right-handed shooter). This provides a rock-solid position when shooting from a stand. The second half of the video shows how this works.

SSG Sherri Gallagher — How to Read the Wind Video

Reading Wind Sherri Gallagher

Sgt Sherri GallagherThe ability to read the wind is what separates good shooters from great shooters. If you want to learn wind-doping from one of the best, watch this video with 2010 National High Power Champion (and U.S. Army 2010 Soldier of the Year) Sherri Gallagher. Part of the USAMU’s Pro Tips Video Series, this video covers the basics of wind reading including: Determining wind direction and speed, Bracketing Wind, Reading Mirage, and Adjusting to cross-winds using both sight/scope adjustments and hold-off methods. Correctly determining wind angle is vital, Sheri explains, because a wind at a 90-degree angle has much more of an effect on bullet lateral movement than a headwind or tailwind. Wind speed, of course, is just as important as wind angle. To calculate wind speed, Sherri recommends “Wind Bracketing”: [This] is where you take the estimate of the highest possible condition and the lowest possible condition and [then] take the average of the two.”

It is also important to understand mirage. Sheri explains that “Mirage is the reflection of light through layers of air, based off the temperature of the ground. These layers … are blown by the wind, and can be monitored through a spotting scope to detect direction and speed. You can see what appears to be waves running across the range — this is mirage.” To best evaluate mirage, you need to set your spotting scope correctly. First get the target in sharp focus, then (on most scopes), Sheri advises that you turn your adjustment knob “a quarter-turn counter-clockwise. That will make the mirage your primary focus.”

Reloading Tip: Bullet Bearing Surface and Pressure

USAMU Bullet Ogive Comparision Safety Reloading
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).

Bullet 1 (L-R), the RN/FB, has a very slight taper and only reaches its full diameter (0.284″) 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!


This article from the USAMU covers an important safety issue — why you should never assume that a “book” load for a particular bullet will be safe with an equal-weight bullet of different shape/design. The shape and bearing surface of the bullet will affect the pressure generated inside the barrel. This is part of the USAMU’s Handloading Hump Day series, publiches on the USAMU Facebook page.

Beginning Handloading, Part 13:
Extrapolating Beyond Your Data, or … “I Don’t Know, What I Don’t Know!”

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.

The researchers ensure their data is safe with the bullet yielding the highest pressure. Thus, all others in that group should produce equal or less pressure, and they are safe using this data.

However, bullet designs include many variables such as different bearing surface lengths, hardness, and even slight variations in diameter. These 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 length (BSL) is often overlooked when considering maximum safe powder charges and pressures. In photo 1 (at top), note the differences in the bullets’ appearance. All three are 7mm, 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.

Bearing Surface Measurement Considerations
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 deceiving.

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.]
