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.

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.

Do you enjoy shooting pistols for sport, or perhaps you carry a handgun for self-defense? If you’re like most of us, you might benefit from a “refresher course” on the fundamentals of handgun shooting. The NRA has created a useful Infographic that covers important basics of handgun marksmanship — key things such as Sight Alignment and Trigger Control. Here are the first two (2) lessons. Click the link below to see all SIX (6) training topics: Sight Alignment, Sight Focus, Trigger Control, Breath Control, Hold Control, and Follow-Through.

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.

Photo 2: The Perils of Measuring Bearing Surface Length with Comparators
USAMU Bullet Ogive Comparision Safety Reloading

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.]

Match Etiquette: Be Prepared, Know the Rules and Course of Fire

Match Etiquette USAMU Course of Fire Rules SFC Norman Anderson CMP Rulebook NRA

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.
CMP Match Etiquette

Match Etiquette USAMU Course of Fire Rules SFC Norman Anderson CMP Rulebook NRAKnow 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 two different Rulebooks:

The 2016 4th Edition of the CMP Competition Rules for CMP Games Rifle and Pistol Matches governs all CMP-sanctioned matches for As-Issued Military Rifle and Pistol events including Special EIC Matches that are fired with As-Issued Military Rifles or Pistols.

The 2016 20th Edition of the CMP Competition Rules for Service Rifle and Service Pistol governs sponsored and sanctioned matches for Service Rifle, Service Pistol and .22 Rimfire Pistol events, including National Trophy Rifle and Pistol Matches, Excellence-In-Competition (EIC) matches and other CMP-sanctioned competitions.

High-Volume Case Lubrication — Tips from the USAMU

accurateshooter USAMU Handloading hump day case lube lubrication spray can cartridge brass reloading marksmanship

Each Wednesday, the U.S. Army Marksmanship Unit publishes a reloading “how-to” article on the USAMU Facebook page. Recently the USAMU’s reloading gurus looked at the subject of case lubrication. Tasked with producing thousands of rounds of ammo for team members, the USAMU’s reloading staff has developed very efficient procedures for lubricating large quantities of cases. This article reveals the USAMU’s clever “big-batch” lube methods. For other hand-loading tips, visit the USAMU Facebook page next Wednesday for the next installment.

Rapid, High-Volume Case Lubrication

Today’s topic covers methods for quickly applying spray lube to cartridge cases prior to sizing. A typical order for this shop may be 25,000 rounds, so [speeding up] the lubrication process can be a real time-saver. While your ammunition lots probably aren’t this large, the efficient methods discussed here may help save a considerable amount of time over your handloading career. Our case lubrication rates range from 1500-1600 cases per hour, to 2400-2500 cases per hour, depending on caliber.

This shop uses virgin brass, whereas most home handloaders use fired brass, which necessitates some small changes at times. These will be discussed as they arise. Begin with fired brass that has been tumbled clean.

Ensure as much tumbling media as possible is removed from the brass, as when it gets into a size die, it can dent cases significantly. This is a good time to round out dents in the case mouths using a tapered tool to prevent damage from the decapping stem.

First, dump the clean cases into a large box or reloading bin. Shake the bin back and forth so that many cases are oriented with the mouths up. Next, pick up as many cases as is convenient with the mouths “up”, from natural clusters of correctly-oriented cases. With 7.62mm-size cases, this is usually 3-4, and with 5.56mm cases, this can be up to 8-10. Place the cases into the rack slots, mouth-up. Doing this in groups rather than singly saves considerable time. Once these clusters have been depleted, it will be time to re-shake the bin to orient more cases “up.”.

This photo shows a case lubrication rack made by a USAMU staffer.

Naturally, adjust the spacing to best fit the calibers you reload. We have found this size … convenient for handling through the various phases of case lubrication/transfer to progressive case feeders for processing. Note that the 1/2-inch angle does not cover much of the critical case area at the base, just forward of the extractor groove, where most re-sizing force will be exerted. As the USAMU uses virgin brass, less lubrication is required for our brass than would be needed for Full Length (FL) sizing of previously-fired brass.

NOTE: The amount applied using our rack is easily enough for our purpose. If using fired brass, be sure to adequately lube this base area to avoid having cases stick in the full-length sizing die.

Using a spray lube, coat the cases adequately, but not excessively, from all sides. Be sure to get some lube into the case mouths/necks, in order to reduce expander ball drag and case stretching/headspace changes. The spray lube this shop uses does not harm primers or powder, and does not require tumbling to remove after lubing.*

accurateshooter USAMU Handloading hump day case lube lubrication spray can cartridge brass reloading marksmanship

Take a close look at the photo above. The USAMU shop uses a common kitchen turntable, which allows the rack to be rotated easily. We place this in a custom-made box which prevents over-spray on to floors and walls.

Angled Box Method for Smaller Cases to be Neck-Sized
A refinement of the above method which especially speeds processing of 5.56x45mm cases is as follows. A small cardboard box which holds about 100 cases is fitted with an angled “floor” secured by tape. With the smaller 5.56mm cases, usually about 8-10 cases per handful can be picked up, already correctly-oriented, and placed into the box together. This prevents having to place them into the rack slots, saving time.

accurateshooter USAMU Handloading hump day case lube lubrication spray can cartridge brass reloading marksmanship

HOWEVER, note that this does not allow nearly as much lube access to the case bodies as does the rack. For our purposes — neck-sizing and setting neck tension on new brass, this works well. If using this procedure with fired brass, take steps to ensure adequate lube to prevent stuck cases.

As always, we hope this will help our fellow handloaders. Good luck, and good shooting!


*A two-part test performed here involved spraying primed cases heavily, while getting more lube into the case mouth/body than even a careless handloader would likely apply. The second part of the test involved literally spraying considerable quantities of the lube directly into the cases, drenching the primers. After a several-day wait to allow the lube to penetrate the primers, they were then fired in a test barrel. All fired normally; no unusual reports were noted. This bolstered confidence that normal amounts of the lube would not adversely affect our ammunition, and we have been pleased with the results over several years.

Reloading Tip: How to Set Optimal Case Neck Tension

USAMU handloading Neck Bushing Die tension springback interchangeable bushings

Each Wednesday, the U.S. Army Marksmanship Unit (USAMU) publishes a reloading “how-to” article on the USAMU Facebook page. This week the USAMU’s reloading gurus addressed a question frequently asked by prospective handloaders: “How much neck tension is optimal, and how should I select a neck bushing size?” The USAMU offers a straight-forward answer, suggesting that hand-loaders start with a neck bushing that sizes the neck so that it is .003″ less than the loaded outside diameter with bullet in place. From there, you can experiment with more or less tension, but this is a good starting point for many popular cartridge types.

USAMU Reloading

Determining Optimal Case-Neck Tension

This week, we examine determining the correct case neck tension for optimum accuracy. Our method is simple, but relies on the use of case sizing dies which accept interchangeable neck diameter bushings graduated in 0.001″ increments. (Those readers using fixed-diameter dies with expander balls aren’t forgotten, however. Methods of tailoring these dies for proper neck tension will be found below.)

In our experience across many calibers, sizing case necks 0.003″ under the loaded-case neck diameter usually yields excellent accuracy. In other words, the sized case neck expands 0.003″ when the bullet is seated.

USAMU handloading Neck Bushing Die tension springback interchangeable bushings

USAMU handloading Neck Bushing Die tension springback interchangeable bushingsBushing Choice for Optimal Sizing
Over the years, we have periodically experimented with increasing neck tension to possibly improve accuracy. In testing with machine rests at 300/600 yards, accuracy often deteriorated as neck tension increased; thus, 0.003″ expansion (from sized neck to loaded neck) is where we usually start.

Using the .260 Remington as an example, our loaded cartridge case necks measure 0.292”. Simply subtract 0.003” from that, and use a bushing that sizes necks to 0.289” (after springback). There are exceptions — sometimes, brass may be a bit soft or hard. Some case necks might need, say, 0.001” more tension, but in general, this works well.

This .003″ standard of neck tension works very well for single-loaded, long range cartridges. Depending on your caliber and firearm, it MAY also work very well for magazine-fed cartridges. If this neck tension proves inadequate for your purpose, one can increase neck tension as needed while monitoring for possible accuracy changes.

Special Considerations for Coated Bullets: If you are using moly-coated bullets, this significantly reduces the “grip” of the case neck on the bullet, and you can expect to have to tighten your case necks accordingly — particularly for magazine-fed ammunition. In any event, we do not crimp rifle cartridges, and advise against it for accuracy handloads.

Tips for Using Expander Balls
Many savvy handloaders avoid the use of expander balls in high-accuracy reloading, if possible. These can stretch cases and/or disturb the concentricity of the case neck vs. case body. If using a die with an expander ball, tapering both ends of the ball and polishing it to a mirror finish can significantly reduce these effects. (Special carbide expander ball/decapping stem sets are available for this as well.)

The typical dies used with expander balls are intended to take any cases the user may find, and size them down well below the ideal “spec” to ensure any cases will give good neck tension. The necks are then expanded up to provide heavy to medium neck tension as the expander ball exits the neck. The brass is over-worked, leading to premature work-hardening, and seated-bullet concentricity may suffer. However, the cartridges produced are perfectly adequate for most handloaders. Those who seek finest accuracy generally prefer not to over-work their brass if possible.

Another Option — Custom-Honed FL Dies
There are companies which offer to convert one’s standard dies to accept neck bushings, and that gives excellent flexibility. Another, more “old-school” approach, is to have the neck of one’s FL die honed out to the desired diameter for sizing, based on one’s case neck thickness. The expander ball may then be reduced until it barely touches the case necks after sizing, or it may be eliminated entirely. However, once performed, this modification is permanent and leaves fewer options than the bushing route, if one later changes case neck thickness.

Those shooters who turn their case necks for optimum neck wall thickness uniformity, or for a tight-neck chamber, will want to take the reduced neck wall thickness into consideration. For example, when setting up a 7mm match rifle to use a standard hunting die without an expander ball, the slightly thinner necks resulted in a perfect 0.003″ reduction in the fired-neck diameter. The result was a low-cost die that fit with custom precision and yielded excellent, match accuracy!

Sling Shooter vs. Mechanical Rest — Man vs. Machine

Man versus machine USAMU AR15 M16 High Power National Record

Can a human, with a sling, shoot as well as a mechanical rest? The answer is “yes” (at least once in a great while) IF that sling shooter can deliver a record-breaking performance. Here’s an interesting tale of man vs. machine from our archives…

The USAMU posed an interesting challenge — could one of their shooters match the performance of a mechanical rest? Who would win in this battle between man and machine? You might just be surprised. At 600 yards, with an AR-platform rifle, the results can be remarkably close, based on targets provided by the USAMU. When clamped in a test rig, a USAMU M16A2 produced a 200-18X group with handloads. The USAMU says this was “one of our better 20-shot groups at 600 yards, testing ammo from a machine rest”. Can a human do better?

Man versus machine USAMU AR15 M16 High Power National Record

Remarkably, a human soldier came very close to matching the group shot from the machine rest. The photo below shows a 20-shot group shot by a USAMU marksman with sling and iron sights, using USAMU-loaded ammunition. The score, 200-16X, was nearly the same. As you can see, the USAMU rifleman didn’t give up much to the machine rest, even at 600 yards!

In fairness, this was no ordinary human performance. The 200-16X score was a new National Record set in December, 1994. This was fired by PFC Coleman in an Interservice Match at Okeechobee, Florida. Brilliant Performance.

Competition Tips from 3-Gun Wizard Daniel Horner

There’s no denying that 3-Gun competition is growing in popularity nationwide. Using a pistol, rifle and shotgun to shoot multiple targets at varying distances is exciting and challenging. Here are some pointers for performing better on the 3-Gun range by the USAMU’s SSG Daniel Horner, a two-time winner of Crimson Trace’s Midnight 3-Gun Invitational (M3GI) match.

Competing in Night-Time Stages
“I use the same gear all year long, so when it comes time for this match (the M3GI), I just adapt the guns, so they will work for the night time,” stated Daniel Horner. “I attach the Crimson Trace lasers and lights to the guns in whatever is the easiest way possible. Last year I just screwed a rail to my shotgun with wood screws. So, people can compete with pretty much whatever they have available and make it work.” Horner also recommends using a pair of head-mounted lamps. One can illuminate your firearms’ iron sights while the other headlamp is aimed at the targets.

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.”

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!

Bullet Bell Curve — Sorting by OAL vs. Base to Ogive

Bullet, Sort, Jacket, Sierra, USAMU, Sort, Bell Curve, Distribution, OAL

The USAMU recently published a “how-to” article about bullet sorting. While many of us may sort bullets by base-to-ogive length (and/or weight), the USAMU story explores the “how and why” of sorting bullets by Overall Length (OAL). Read the article highlights below, and make your own decision as to whether OAL sorting is worth the time and effort. Bryan Litz of Applied Ballistics says that sorting by OAL is not a bad idea, but base-to-ogive bullet sorting probably represents a better investment of your time.

USAMU

Bullet Sorting by Overall Length

We’d like to share a specialized handloading technique which we’ve long found beneficial to our long-range (600 yards and beyond) accuracy. Sorting of bullets for extreme long range (LR) accuracy is not difficult to do, but some background in theory is needed.

Here at USAMU’s Handloading Shop, we only sort individual bullets for the most demanding Long-Range applications and important competitions. Only the most accurate rifles and shooters can fully exploit the benefits of this technique. The basic sorting process involves measuring the Overall Length (OAL) of the bullets, and grouping them in 0.001″ increments. It’s not unusual to find lots of match bullets that vary as much as 0.015″-0.020″ in length throughout the lot, although lots with much less variation are seen as well. Even in bullet lots with 0.015″ OAL variation, the bullet base-to-ogive length will show much less variation. Hence, our basic sort is by bullet OAL. One obvious benefit of sorting is easily seen in the attached photo. The few bullets that are VERY different from the average are culled out, reducing probable fliers.

How does one know what OAL increments to use when sorting? The answer is simple. As each lot of bullets is unique in its OAL distribution, it’s best to sample your bullet lot and see how they are distributed. In the attached photo, you will see a set of loading trays with a strip of masking tape running along the bottom. Each vertical row of holes is numbered in 0.001″ increments corresponding to the bullets’ OAL. A digital caliper makes this task much easier. As each bullet is measured, it is placed in the line of holes for its’ OAL, and gradually, a roughly bell-shaped curve begins to form.

Note that near the center, bullets are much more plentiful than near the edges. At the extreme edges, there are a few that differ markedly from the average, and these make great chronograph or sighting-in fodder. We recommend using a sample of 200 bullets from your lot, and 300 is even better. Some bullet lots are very consistent, with a tall, narrow band of highly-uniform bullets clustered together over just a few thousandths spread. Other lots will show a long, relatively flat curve (less uniform), and you may also see curves with 2 or more “spikes” separated by several 0.001″ OAL increments.

Bullet Sorting (OAL vs. Base-to-Ogive vs. Weight) — Litz Talks

I’m often asked what is a the best measure to sort bullets by, and the answer (to this and many other questions in ballistics) is: it depends.

Choosing to sort by overall length (OAL), base to ogive (BTO), bearing surface, weight, etc. can get overwhelming. Shooters typically look for something they can measure, which shows a variation and sort by that. It’s common for dimensional variations to correlate. For example, bullets which are longer in OAL are typically also shorter in BTO, and have longer noses. All these are symptoms of a bullet that was pushed a little further into the pointing die, or possibly had more than average lube while being swaged. So in essence, if you sort by BTO, you’re measuring one symptom which can indicate a pattern in the bullets shape.

So, the question still stands — what should you measure? You’ll always see more variation in OAL than BTO, so it’s easier to sort by OAL. But sometimes the bullet tips can be jagged and have small burrs which can be misleading. Measuring BTO will result in a lower spread, but is a more direct measure of bullet uniformity.

Then there’s the question of; how much variation is too much, or, how many bins should you sort into? Shooters who see 0.025” variation in BTO may choose to sort into 5 bins of 0.005”. But if you have only 0.005” variation in the box, you’ll still sort into 5 bins of 0.001”. What’s correct? You have to shoot to know. Live fire testing will answer more questions, and answer them more decisively than any amount of discussion on the subject. The test I recommend is to identify bullets on the extreme short end of the spectrum, and some on the extreme long end. Load at least 10 rounds of each, and take turns shooting 5-shot groups with them. If there is a difference, it will be evident. The results of the testing will answer your question of: should I sort based on X, Y, or Z?”

You can read more discussion on this and other similar subjects in the new Ballistics & Bullets board in the Accurateshooter.com forum. Heres a link to the thread which is discussing bullet sorting: Bullet Sorting Thread

How to Remove the Primer Crimp in Military Cartridge Brass

Primer Crimp Milsurp Brass

Each Wednesday, the U.S. Army Marksmanship Unit publishes a reloading “how-to” article on the USAMU Facebook page. On older “Handloading Hump Day” post covers removal of military primer pocket crimps. If you ever use surplus military brass, you really should this article. It contains vital information “learned the hard way”. The writer has tried many different options for removing/swaging out crimps. He weighs the pros and cons of various methods and provides some advice that will save you time and headaches. Visit the USAMU Facebook page next Wednesday for more informative articles for handloaders.

A common question, and important issue with US GI surplus 5.56 brass is “what to do with the primer crimp?” Our Handloading Shop does not prime/re-prime GI 5.56 brass, as we receive it in virgin state (primed) and don’t reload it. However, our staff has extensive private experience handloading GI brass in our own competitive shooting careers, and have several tips to offer.

Once the brass is full-length sized and decapped, the staked-in ring of displaced metal from the primer crimp remains, and hinders re-priming. Some swaging tools exist to swage out this ring, allowing free access to the primer pocket. Some are stand-alone products, and some are reloading-press mounted. Early in this writer’s High Power career, he used the common press-mounted kit several times, with less than stellar results.

Setting Up Swaging Tools
Surplus brass tends to come from mixed lots, and primer crimp varies from very mild to strong. Also, primer pocket dimensions vary. So, setting up this “one size fits most” tool involves trying to find a happy medium for a selection of different types of brass in your particular lot. Some are over-swaged, some under-swaged, and some are “Just Right.” Overall, it was a time-consuming and sub-optimal process, in this writer’s experience.

Cutting Out the Crimp Ring with a Chamfer Tool
[After trying swaging tools] this writer evolved to using the ubiquitous Wilson/RCBS/Other brands chamfer and deburring tool to cut out only the displaced crimp ring at the top of the primer pocket. One caution: DON’T OVER-DO IT! Just a little practice will let the handloader develop a “feel” for the right degree of chamfer that permits easy re-priming without removing so much metal that primer edges start to flow under pressure. For this writer, it was three half-turns of the tool in the primer pocket, with medium pressure.

Here, as with all bulk reloading operations, mechanization is our friend. A popular reloading supply house has developed an inexpensive adaptor that houses the chamfer/deburr tool (retained by an allen screw) and allows mounting in a hand drill or drill press. This speeds the operation significantly, as does use of one of the popular Case Preparation Stations that feature multiple powered operations. (Say good-bye to carpal tunnel syndrome and arthritis!)

military crimp removal USAMU

One advantage of chamfering the primer pockets lightly to remove remnants of primer crimp, vs. swaging, is that primer pockets are not loosened in this process. US GI (usually LC) NATO 5.56 brass has a great reputation for longevity due to the superior hardness of the case head vs. some softer brands of commercial brass. This means the brass will stand up well to multiple full-pressure loads without loosening primer pockets, and the chamfering method helps support this benefit.

Powered Case Prep Centers — What to Look For
A word of advice (often learned the hard way) — think carefully before jumping on the “latest/greatest” case prep center. One with a proven, long-time track record of durability and excellent customer support has a lot going for it, vs. the flashy “new kid on the block.” Analyze the functions each case prep center can support simultaneously — i.e., can it chamfer, deburr and clean primer pockets all at the same time, without having to re-configure?

Do the tool-heads that come with it look truly functional and durable? If not, can they be easily replaced with proven or more-needed versions, such as a VLD chamfer tool, or a solid/textured primer pocket cleaner rather than a less-durable wire-brush type?

military crimp removal USAMUTips for Priming with Progressive Presses
When re-priming, a couple of factors are worth noting. When re-priming using either single-stage presses, hand tools, or bench-mounted tools (such as the RCBS bench-mounted priming tool), precise alignment of the primer pocket entrance with the primer is easily achieved, and priming goes very smoothly. When using certain progressive presses, due to the tolerances involved in shell-heads, etc., one may occasionally encounter a primer that isn’t quite perfectly aligned with the primer pocket.

If resistance is felt when attempting to re-prime, DO NOT attempt to force the primer in — doing so can be dangerous! Rather, just exert SLIGHT upward pressure to keep the primer in contact with the case-head, and with the support hand, move the case back/forth a trifle. The primer will drop into alignment with the primer pocket, and then prime as usual. After priming, check each seated primer by feel. Ensure it is below flush with the case head (cleaning primer pockets helps here), and that there are no snags, burrs or deformed primers.


More Info on Primer Pocket Swaging
For more information about removing military crimps in primer pockets, we recommend you read Get the Crimp Out on the Squibloads Gun Thoughts Blog. This is a detailed, well-illustrated article that shows how to use various primer pocket reamers/cutters. It also has a very extensive discussion of swaging using CH4D, RCBS, and Dillon tools. The Squibloads author had much better luck with swaging tools than did the USAMU’s writer — so if you are considering swaging, definitely read the Squibloads article.

Brain Trust: Emil Praslick Offers Advice on Wind Reading

Emil Praslick USAMUTo succeed in long-range shooting matches, given the high level of competition these days, you’ll need solid wind-reading abilities. We’ve found an article by SFC Emil Praslick III, retired USAMU Service Rifle coach and U.S. Palma Team Coach, that can help you make better wind calls in competition.

Emil Praslick, now retired from the U.S. Army, is considered one of the best wind gurus in the United States, if not the world. During his service with the USAMU he authored an excellent two-part article on wind reading that is available on the CMP (Civilian Marksmanship Program) website. Both articles contain helpful illustrations, and are “must-read” resources for any long-range shooter–not just Service Rifle and Highpower competitors.

Click to Read Articles:

Reading the Wind (Part One) | Reading the Wind (Part Two)

Part One covers basic principles, tactics, and strategies, with a focus on the 200-yard stages. Emil writes: “There are as many dimensions to ‘wind reading’ as there are stages to High Power competition. Your tactical mindset, or philosophy, must be different for the 200 and 300 yard rapid-fire stages than it would be for the 600 yard slow-fire. In the slow-fire stages you have the ability to adjust windage from shot to shot, utilizing the location of the previous shot as an indicator. Additionally, a change to the existing conditions can be identified and adjusted for prior to shooting the next shot.”

In Part Two, Praslick provides more detailed explanations of the key principles of wind zeros, wind reading, and the “Clock System” for determining wind values: “The Value of the wind is as important as its speed when deciding the proper windage to place on the rifle. A 10 MPH wind from ’12 o-clock’ has No Value, hence it will not effect the flight of the bullet. A 10 MPH wind from ‘3 o’clock’, however, would be classified as Full Value. Failure to correct for a Full Value wind will surely result in a less than desirable result.”

USAMU Praslick wind clock

Praslick also explains how to identify and evaluate mirage:

Determine the accuracy of the mirage. Mirage is the reflection of light through layers of air that have different temperatures than the ground. These layers are blown by the wind and can be monitored to detect wind direction and speed.

Focus your scope midway between yourself and the target, this will make mirage appear more prominent. I must emphasize the importance of experience when using mirage as a wind-reading tool. The best way to become proficient in the use of mirage is to correlate its appearance to a known condition. Using this as a baseline, changes in mirage can be equated to changes in the value of the wind. Above all, you must practice this skill!

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.
