The U.S. Army Marksmanship Unit regularly publishes technical articles on the USAMU Facebook page. One informative USAMU article covered mechanical issues and related ignition irregularities that can cause vertical fliers even with good ammunition in an otherwise excellent rifle. We highly recommend you read this article, which offers some important tech tips.
Vertical Dispersion: Mechanical/Ignition Issues?
Poor or inconsistent ignition has long been known to be one of the “usual suspects” when one encounters vertical fliers that just shouldn’t be there. By having a sense of some of the basic principles involved, and a few basic areas to check, the shooter may avoid colsiderable frustration, not to mention time, expensive loading components and barrel wear.
Is your well-built rifle of high-quality components plagued with vertical fliers across more than 1-3 handload combinations? Consider the bedding, crown and scope/sight mounts. Are they correct? If so, then you might check for ignition issues before boldly undertaking an extensive, expensive, and quite possibly fruitless quest for the “magic handload”.
SEEING IS BELIEVING: While the author had been aware for many years that poor ignition should be considered and ruled out when dealing with vertical fliers in an otherwise-excellent rifle, actually seeing the problem and its almost instantaneous cure really drove the lesson home.
He was working with a “dot” rifle – a .22 LR match rifle that really stacked bullets into little piles at 50 yards and beyond. With one lot of ELEY Tenex, it produced consistent “bughole” groups at 50, but with another, selected lot of Tenex, similar groups were regularly ruined by single, vertical fliers that did not appear in other rifles. Rather than spending days burning up expensive, select ammunition looking for “magic lots”, he contacted a well-respected rimfire gunsmith and explained the situation.
Without so much as batting an eye, the highly-experienced ‘smith tore into the rifle’s action, and quickly found the cause(s) of the problem. He discovered a demonstrably weak firing pin spring, plus a chip out of the face of the firing pin where it contacted the cartridge rim.
After replacing and tuning the offending parts, the rifle immediately began shooting tiny, bughole groups with the previously “unacceptable” lot of Tenex. Centerfire rifles can also benefit from ensuring positive, consistent ignition. A wise riflesmith is literally worth his weight in gold!
So, what are some issues we as shooters can inspect in our rifles to help determine if ignition woes could be part of our problem? At the club level, ask yourself if that “experienced” Remington, Winchester 70, or even Springfield-based match bolt gun you’re using is still running its’ original 40-80 year-old factory striker spring? If so, a new replacement is cheap insurance against current or future problems. (And BTW, it might be best to stick to the normal, factory-spec spring weight. A super-powerful spring can cause vertical, just as a weak one one can.) Along with that, a routine check for proper firing-pin protrusion is a quick preventive measure that can rule out potential issues.
Other areas to consider are the centering and consistency of the firing pin’s operation in the bolt. Admittedly, with the increasing use of precision-machined custom actions, this is becoming less an issue every day. Below is the firing pin assembly from a custom BAT action:
However, particularly with factory actions, a very quick and easy check is to remove the bolt, let the firing pin go forward, and look at the firing pin tip through the firing pin hole. Is the tip off-center in the hole, and possibly striking it as it moves forward? Is the hole out-of-round or burred from being struck repeatedly? If so, a trip to the riflesmith is likely in order.
Similarly, machining issues in the bolt/firing pin system can lead to rough and erratic firing pin movement, in which the firing pin drags against an internal surface of the bolt. In high-quality rifles these issues are relatively rare, but not unheard-of, and it takes mere minutes to rule them out. It may be worthwhile to remove the cocking piece/firing pin/spring assembly and look for any unusual gouges, dings, peening, burrs or signs of abnormal wear.
This task is especially easy with Winchester 70s, Springfields, and the similar Mauser 98s, involving little more than the push of a button and unscrewing the cocking piece assembly. This is just one of the many reasons these tried-and-true actions have earned such a loyal following in the field, among hunters who must maintain their rifles away from a shop.
Particularly with older rifles, watch for and remove excess grease (or even Cosmoline!) from both the firing pin assembly and inside the bolt. This can help improve firing pin speed and consistency. Other bolt-action designs may need a take-down tool or other measures.
As part of this inspection, AFTER ENSURING THE RIFLE IS UNLOADED, slowly cock the rifle, dry-fire, and repeat several times. Listen carefully near the action for inconsistency in the sounds it generates. Does the striker falling make the same sound each time? Do you hear or feel grinding upon operation? If so, where?
Be sure to check the operation of the cocking piece (bolt shroud), firing pin within the bolt shroud, the cocking piece cam and the rear of the bolt body where the cocking piece cam operates. As with our examination for abnormal wear marks discussed above, look for marks indicating roughness or a possible need for light polishing. Then, clean and lightly grease the bearing surfaces while you’re at it.
Remington 700 bolt shroud and cocking cam
These are relatively easy checks that shooters can undertake to perform a preliminary inspection on their own. Other mechanical issues can also cause ignition issues, chiefly centered around the action of the trigger, sear and sear spring. If these are suspected, a trip to an experienced, qualified riflesmith for diagnosis is recommended. We hope you find this information helpful! Join us again next week, and in the meantime, enjoy the shooting sports safely!
For many years, the U.S. Army Marksmanship Unit (USAMU) regularly published reloading “how-to” articles on the USAMU Facebook page. In this article, the USAMU’s reloading gurus address a question frequently asked by prospective handloaders: “Should I buy a single-stage press, or a progressive?” The USAMU says the best answer is Solomon-esque in both its wisdom and simplicity: “Get BOTH!” However, there is definitely more to the issue, as the USAMU explains below.
Progressive Press Safety Considerations
by USAMU Staff
Many are the beginning handloaders who have asked a friend about their “setting up” a progressive press for them. The idea is that the newbie could then just feed in components and crank out buckets of practice ammo without needing to really learn much about handloading. Tempting though this might be, that’s simply not how it works. Such an approach might be ok if there were never a malfunction with either press or operator, but that’s unrealistic. Our hypothetical newbie would then lack the knowledge to problem-solve most situations.
Worse yet, several different handloading operations would be occurring at different stations on the progressive press at the same time. It takes an experienced operator to keep track of, and truly understand the significance of, all those potential mini-problems. Loading without this experience is a recipe for potential disaster – such as a double powder charge (especially with pistol cartridges) dropped while the loader was attending to some other function, etc. Progressives are an animal unto themselves, and while they offer many benefits, they do take some getting used to – even by experienced handloaders!
ILLUSTRATIVE HORROR STORY
Here, enter a 40-year veteran handloader who decided to jump onto the progressive bandwagon late in his career, having used only single-stage presses all his life. A High Master NRA High Power Rifle competitor, he had no background in competitive pistol shooting, where historically most progressive presses are found.
Experienced Action Pistol shooters have typically encountered multiple episodes in which shooters “skipped” a powder charge for some reason, leading to a squib round and a bullet possibly lodged in the bore. Thus, at matches, it’s reflexive for them to yell “STOP!” in unison if they see a shooter get a “click” vs. a “bang”, and rack the slide to keep firing. This writer has personally seen several pistols saved in just such scenarios over the years.
Click No Bang — What NOT to Do
Our High Master set up a popular progressive press and began turning out .223 Rem 100-yard practice ammo with abandon. He was using a moly-coated 52gr match bullet and an economical, fast-burning surplus powder that gave great accuracy. Once on the range, he began practicing strings of rapid-fire. All was well, until he heard “Click!” rather than “Boom”.
Lacking the above experience or onlookers to halt him, he reflexively operated the charging handle on his expensive, custom NM AR15 Service Rifle, and the next trigger squeeze reportedly registered on seismographs over at least a three-state radius. He sat, uninjured but bewildered, until the hail of expensive bits and pieces quit raining down around him.
When the smoke cleared, he immediately cursed the horrid, evil, demonically-possessed progressive press for this, his first-ever reloading mishap. His $1400 NM upper was ruined, but thankfully, his $800 pre-ban lower… and he had escaped injury.
This tale is told not to discourage the use of progressive presses, but to emphasize the need to EASILY and IMMEDIATELY KNOW what is happening with the press at each station, every time the handle is cranked. Not to do so is, as they say, “bad ju-ju.”
It illustrates why we at the USAMU Handloading Shop agree in recommending that new handloaders should begin with a single-stage press. Once one thoroughly learns the steps in each phase of handloading by repeated experience, then one will be qualified to move on to a progressive press.
The single-stage press will REMAIN virtually indispensable for one’s entire handloading career, even after having purchased a progressive press (or two). There are endless small projects that are best handled on a single-stage press, and a poll of USAMU’s Handloading staff reveals that not one would willingly be without his single-stage press, despite owning at least one progressive.
The U.S. Army Marksmanship Unit regularly publishes reloading “how-to” articles on the USAMU Facebook page. One very good article, part 5 of a 6-part series, focused on Progressive Presses. This article explains proper procedures for Auto-Indexing Progressives, which advance the shell-plate with every pull of the handle. Auto Progressives are very efficient, but they also require special attention and focus, because so many things are happening at once. You need to train yourself to watch every station. If you run a progressive press now, or are considering getting a progressive, we recommend you read this article. Visit the USAMU Facebook page for other helpful handloading guidance.
Progressive Loading Presses — Self-Advancing Shellplate Type
Recently, we addressed manually-operated progressive presses for the beginning handloader. This type press requires one to manually advance the shellplate after each handle stroke. An advantage for beginners is that nothing happens at any station until the loader wants it to. This helps users avoid problems from clearing malfunctions without noticing that the shellplate has advanced itself. (Read Previous USAMU Article on Manual Progressives.)
The next, more luxurious type progressive press advances the shellplate automatically whenever the handle is cycled. [Editor: This is also called an “Auto-Indexing” Progressive Press.] Typically, each stroke automatically sizes and primes a case, operates the powder measure (if used) and seats a bullet. Some also have case feeders that automatically put a new case in the shellplate with every cycle. Others require the loader to insert a case each cycle. With both types, the loader usually puts a bullet on each sized/primed/charged case.
[CAVEAT: While our Handloading Shop has several progressive presses, ALL of our powder charges are thrown/weighed by hand. We do not use powder measures on our presses. Our progressives are used for brass preparation, priming, seating, etc., but not for fully-progressive loading.]
The manually-advanced press can be a boon to beginners, but as one gains experience it can be a mixed blessing, depending on one’s style. If one pays close attention to every operation and loads without distractions, the manual press is very reliable and allows full scrutiny of each round as it is loaded. However, if one easily drifts into day-dreaming, or isn’t focused on paying careful attention at all times, the manual progressive can be a bit of a liability. The opportunity for forgetting a powder charge, leading to a squib load, is ever-present. [Editor: A lock-out die can help reduce the risk of a squib load, or a double-charge. See below.]
The automatically-advancing progressives help prevent this by ensuring a powder charge will be dropped each time the handle is operated. Experienced handloaders often appreciate this feature due to the savings of time and effort. Individual preferences between the two press styles are influenced by several factors. These include one’s comfort with more- vs. less-complicated mechanisms, how often one changes calibers (case feeders often must be converted, in addition to dies and shellplates), how many rounds one loads annually, relative ease of changing primer mechanisms from small to large, etc. Automatic progressives and their caliber conversion kits tend to be significantly more expensive than manual progressives and caliber conversions from the same maker.
One USAMU handloader, who likes simple, bullet-proof machines and maximum efficiency when converting presses, owns two manually-advanced progressives. One is set up for large primers, and the other for small primers. He can change calibers in the twinkling of an eye. As he loads for many different calibers, this fits his style. Another handloader here is just the opposite. He loads for a few calibers, but in larger quantities. He much prefers his self-advancing press with case-feeder for its speed. He makes large lots of ammo in a given caliber before switching, to improve overall efficiency. His caliber conversion kits are more expensive than those for the manually-advanced progressive, but he uses fewer of them.
Whichever type one chooses, it is VERY important to buy quality gear from a manufacturer with a long, well-established track record for quality, durability and good customer support. Avoid jumping on the “latest, greatest” model until it has a proven track record. For example, this writer knows a loader who got a brand-new, expensive, self-advancing model press some years back, shortly after its introduction. As is too often the case these days, the manufacturer released it before all the “bugs” were worked out.
Better Safe Than Sorry — the RCBS Lock-Out Die
RCBS Makes a “Lock-Out Die” that senses the powder charge. This will halt the Progressive press if you have a double charge, or an undercharge. Your Editor has the Lock-Out Die on his RCBS Pro 2000. It has “saved his bacon” a half-dozen times over the years. It can be used on Dillon and Hornady progressives as well as RCBS machines.
It would not fully seat primers to the correct depth. No amount of adjustment, extra force, or fiddling would do better than to seat primers barely flush with the case head. Any inattention could result in a slightly “high” primer, protruding above the case head. It created a risk for slam-fires, particularly in semi-autos without spring-retracted firing pins, such as the M1 or M1A. In desperation, he had a machinist buddy study the problem and machine a new part to correct it. No dice. Its engineering didn’t permit full primer seating, even with extended parts. He now wishes he’d heeded his shooting buddies’ advice to stick with the “tried and true,” reliable performer they all used.
Whichever press one selects, see if the maker has a kit or list of commonly-replaced parts. Having needed springs, pins, etc. on hand in the rare event that one breaks or “goes missing” can save the day when one is busy loading for a match! Another tip for improving one’s overall loading efficiency (rounds loaded with minimal set-up/tear-down time) is to plan one’s handloading by primer size. For example, if your machine is set to use small primers, load all the calibers that you intend to that take small primers, before converting the press to load large-primer calibers.
In our next chapter, we’ll discuss peculiarities of progressive loading for rifle cartridges, with remedies for problems such as excessive cartridge-case headspace variation when sizing, tips for ensuring best powder charge consistency, and so on. Until then, be safe, and good shooting!
The following article by Tom Alves describes a very practical approach to physical training for those of us who are not as young and spry as we once were. Tom shows us how to give our bodies at least some of the maintenance we give our rifles. While we all realize that our rifles will outlive us, let’s see if we can’t narrow the margin a bit with some personal maintenance that just might help the shooting too!
This article originally appeared in German Salazar’s Rifleman’s Journal, and appears with permission. Sadly, German passed away in 2022. This was a very sad loss of a great marksman and a great shooting sports writer. This Editor also counted German as a close friend, who helped this site in many ways.
A Suggested Training Approach for Older Shooters
By Tom Alves Most articles and discussions regarding competitive shooting center around equipment. Now and then one will come across an article about physical training such as the USAMU piece on Physical Conditioning for Highpower Shooting. If you break the articles down they often discuss “core strength” and durability. The purpose of this paper is to elaborate on those points with a bit different perspective. Many of the articles you will read in books about position shooting and the one mentioned before are directed more toward the younger generation of shooters in their 20s. If you look down the line at a typical high power match these days you are likely to see quite a few folks who are in their middle 30’s and up. Many people in that age range have had broken bones and wear and tear on their joints so a training program needs to take that into account. For instance, while jogging for an extended period for heart and lung conditioning — often called cardio exercises — may be the recommended approach for younger folks, it may be totally inappropriate for older people. The procedure to repair meniscus tears in knees is one of the most frequently performed operations in this country. Another approach one often sees in training to improve core strength is the use of weight machines which isolate certain muscle groups in their operation. I would like to suggest an alternative approach that not only does not require special equipment but uses the body’s muscles in a coordinated fashion in the same way they are used in our natural movements. So, let’s set down some criteria:
1. The approach has to be low impact to conserve joints.
2. One goal is to improve the strength of the core muscles which are the muscles of our trunk that keep us erect and from where all movements initiate.
3. Along with core strength we need flexibility and full range of motion.
4. We want to improve our lung and heart function so we can have a good flow of oxygen going to our organs and muscles to reduce the rate at which we become fatigued during a competitive event.
Before I continue I believe it is appropriate for the reader to understand that I am a fellow shooter and this is a program I have designed for myself based on considerable reading and experience over a number of years. I am not a medical doctor, a formally trained exercise professional or any other type of specialist in the field. Consequently, this information is offered with the advice that you consult your medical advisor or similar authority before you embark on this or any similar regimen.
I will start with core strength and flexibility. Pilates exercises are resistance exercises that can incorporate the use of resistance bands, light weights and the weight of your body parts in order to strengthen the muscles in the abdomen, back, hips, chest and shoulders. The exercises can be performed alone but I recommend attending classes put on by a certified instructor who will ensure that you perform a balanced routine meaning you work on the front and back and both sides of your trunk. As to flexibility, yoga complements Pilates exercises and they are often taught together. In practical terms yoga strengthens through resistance using the weight of the body and increases flexibility by stretching the various muscle groups in a coordinated fashion. Some yoga exercises also work on balance which is helpful in position shooting and life in general. Again, I suggest attending formal yoga classes since an instructor can help you address such things as a joint misalignment. As an example, my right leg healed improperly after the femur was broken and my right foot splays out putting undue load on my left knee. There are a number of books available on Pilates and yoga and some of them get pretty involved; I leave that to the reader to explore. I will list some reference material at the end of the article that I have found useful.
Finally, heart and lung improvement. In order to exercise the heart and lungs while not abusing the joints, particularly the knees and hips, one has to resort to something other than jogging. Walking, bicycling, elliptical machines and swimming may be alternative methods you’d like to consider. Based on my reading, in order to get the most benefit it is important to exercise so that the pulse rate becomes elevated for periods of time rather than kept at a constant rate. The process I use, called PACE, is promoted by Al Sears, MD, http://www.alsearsmd.com/. It is interval training for the non-athlete. In simple terms one exercises, using whatever equipment one desires, to achieve a heart rate in which you are slightly above your ability to bring enough oxygen into your body to sustain the activity for an extended period. This is similar to wind sprints for a sprinter or a football player. After each episode you must rest until you have achieved recovery, meaning you can catch your breath easily. A series of three sets is recommended which covers a total time of about 20 minutes.
Report from the Author — Yes, Training Helps
As a result of this training program I have experienced increased strength in my legs and trunk, less joint stiffness, lower blood pressure, and lower resting pulse rate. The Pilates/yoga classes are usually attended 2 to 3 times a week and the interval training performed twice a week. [The author was 64 when this was first published. He is now 75, and still shooting Palma and Smallbore prone.]
Before I close I would like to touch briefly on two other related subjects: hydration and visual training. When one is exerting oneself, the body produces perspiration to keep the body’s temperature at an acceptable level. As one perspires the blood gets thicker and the ocular fluid in one’s eyes thickens as well. The heart has to work harder to supply oxygen and nutrients to the body so visual and cognitive functions degrade and fatigue sets in rapidly. Essential chemicals called electrolytes are also carried out of the body with the perspiration. As a result, it is necessary to replace moisture and electrolytes to maintain basic health and a competitive level of performance. If one goes on the Internet there is a multitude of articles on hydration. Due to the kindness of my lead Pilates/yoga instructor, Ms. Annette Garrison, I have a pretty comprehensive article on various aspects of hydration that I have included, http://www.ideafit.com/fitness-library/hyponatremia-other-side-hydration-story , for your information.
Last I want to mention visual performance training. The New Position Rifle Shooting, A How-To Guide for Shooters and Coaches by Bill Pullum and Frank Hanenkrat mentions sports vision training amongst other aspects of vision in competitive shooting. If one goes on the Internet you will find training programs directed at golfers, baseball and football players. There is one site that has a demo which, if one looks at it for long, it is obviously very similar to a shooting gallery video game. The training involves rapid recognition and hand-eye coordination. Another source of visual training exercises, along with a wealth of other information, is the book Prone And Long Range Rifle Shooting by Nancy Tompkins.
Hopefully, I have provided some information which will be helpful in improving shooting performance and extending the time you can participate at a competitive level. It is important that you proceed at your own pace. I have pushed myself too hard in the interval training and now have to back off a bit. In closing I would like to thank Annette Garrison and GS Arizona for their help, patience and encouragement.

In the archives of On The Mark magazine, DCM Emeritus Gary Anderson, an Olympic Gold medal-winning shooter in his younger years, offers sage advice for competitive shooters.
In his article Ten Lessons I Wished I Had Learned as a Young Shooter, Anderson provides ten important guidelines for everyone involved in competitive shooting. Here are the Ten Lessons, but you should read the full article. Anderson provides detailed explanations of each topic with examples from his shooting career.
LESSON 1 – NATURAL ABILITY WILL NOT MAKE YOU A SHOOTING CHAMPION.
(You also need hard work, training effort and perseverance.)
LESSON 2 – ANGER IS THE ENEMY OF GOOD SHOOTING.
(The key to recovering from a bad shot is to stay cool, no matter what happens.)
LESSON 3 – BAD SHOTS CAN TEACH YOU MORE THAN GOOD SHOTS.
(Today, error analysis is one of the most powerful tools for improving scores.)
LESSON 4 – NEVER GO WITHOUT A SHOT PLAN.
(A shot plan is a detailed breakdown of each of the steps involved in firing a shot.)
LESSON 5 – PRACTICE IN BAD CONDITIONS AS WELL AS GOOD CONDITIONS.
(Most competitions are fired in windy conditions or where there are plenty of distractions.)
LESSON 6 – CHAMPIONS ARE POSITIVE, OPTIMISTIC PEOPLE.
(Negative shooters expect bad results; positive shooters expect to train hard to change bad results.)
LESSON 7 – IT’S NOT ABOUT WHETHER YOU WIN OR LOSE.
(It’s about how hard you try to win.)
LESSON 8 – YOUR DOG WON’T BITE YOU AFTER SHOOTING A BAD SCORE.
(Hopefully your coach, parents and friends won’t bite you either.)
LESSON 9 – YOUR PRESS CLIPPINGS CAN HURT YOU OR HELP YOU.
(Winning can go to our heads. We start thinking we are so good we don’t have to work hard any more.)
LESSON 10 — YOU NEVER SHOT YOUR BEST SCORE.
(Great champions are always looking for ways to improve.)

To 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.
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.”
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!

The Action Target Sport Plate Rack is specifically designed for .22 LR Rimfire shooting. This rack features six 4″-diameter plates that reset with a provided cable.
Shooting plates is fun. You get immediate feedback — “instant gratification” when you make a hit. When shooting steel inside 100 yards, we like to use .22 LR rimfire guns. The ammo is inexpensive, noise levels are lower (though you still need ear protection), and at close ranges there are fewer issue with ricochets and bullet splash-back. Additionally, for busy folks who don’t have time to reload, you can pick up a .22 LR rifle or pistol, grab a couple $5 boxes of ammo, and get to the range in a few minutes. The convenience means it is easier to shoot every week if you like.
SFC Joel Turner from the USAMU’s Action Shooting Team offers a few pointers on how to shoot plates quickly and accurately. He’s using a centerfire pistol, but the same principles apply for rimfire handguns. Click speaker icon to activate audio.
New .22 LR CP33 Pistol is Great for Plates
If you like shooting plates with rimfire guns, one of the better new pistols for the job is Kel-Tec’s CP33. We tested this interesting handgun at the 2019 SHOT Show Media Day at the Range, and were impressed. The pistol is big, but balances well. The sights are easy to see, and the full-length rail lets you easily mount a variety of optics. The trigger is surprisingly good — better than 90% of rimfire handguns out there. For the plates game, this “quad-stack” gun can handle long stages without mag changes. The standard clear-sided CP33 magazine holds 33 rounds of .22 LR ammo.
If you are interested in an affordable, but very accurate, high-capacity semi-auto rimfire pistol you should consider Kel-Tec’s new CP33. Shooting Sports USA (SSUSA) notes: “The rapid growth of rimfire competition in Steel Challenge has prompted some gun makers to enter the fray. Kel-Tec is one, and their new CP33 .22 LR pistol has a lot of potential.” Popular YouTube host 22 Plinkster tested the gun and reports: “This handgun has been 100% reliable IF I load the magazine the right way… and it’s pretty dog-gone accurate.” The video below shows the best way to load the 33-round magazine:
SSUSA’s testers tried the pistol with a variety of ammo and it consistently shot about one-half-inch for five shots “from a 25-yard sandbag bench rest using the iron sights.” SSUSA noted that the gun disassembles quickly and easily by removing one central pin. That’s a nice feature.
Overall SSUSA’s tester, Chris Christian, was impressed with the gun, saying it balanced well and the sights aligned naturally: “…the neutral-balance-point grip produced an almost instinctive sight alignment.”
Christian used the CP33 in a 6-stage Steel Challenge Match, and did well: “I decided to shoot Rimfire Pistol Iron (RFPI) and used the CCI Mini-Mag. The high-speed ammo ran perfectly. [T]he bright sights and handling qualities let me finish top among iron-sight shooters and even hold my own with C and B class rimfire pistol shooters using optical sights. It would be interesting to put a reflex sight on the gun, and maybe even shoot some Bullseye with it.”
Hunting season is coming up, so it’s time to get your rifle squared away. You’ll want to zero that rifle before the hunt, and you need to know how your shots will impact with a cold barrel.
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.
Efficient cartridges make excellent use of their available powder and case/bore capacity. They yield good ballistic performance with relatively little recoil and throat erosion.
Cartridge Efficiency: A Primer (pun intended!)by USAMU Staff
The U.S. Army Marksmanship Unit (USAMU) published a series of reloading articles on its Facebook Page. In this article, the USAMU discusses cartridge case efficiency and its benefits. While this is oriented primarily toward NRA High Power Rifle and Long Range (1000-yard) competition, these factors also apply to medium/big game hunters. Assuming one’s rifle and ammunition are accurate, key considerations include ballistic performance (i.e., resistance to wind effects, plus trajectory), recoil, and throat erosion/barrel life.
Efficient cartridges make excellent use of their available powder and case/bore capacity. They yield good ballistic performance with relatively little recoil and throat erosion. A classic example in the author’s experience involved a featherweight 7x57mm hunting/silhouette rifle. When loaded to modern-rifle pressures, just 43-44 grains of powder pushed a 139gr bullet at 2900 fps from its 22” barrel. Recoil in this light rifle was mild; it was very easy to shoot well, and its performance was superb.
An acquaintance chose a “do everything” 7mm Remington Magnum for use on medium game at short ranges. A larger, heavier rifle, it used ~65 grains of powder to achieve ~3200 fps with similar bullets — from its 26″ barrel. Recoil was higher, and he was sensitive to it, which hampered his shooting ability.
Similarly efficient calibers include the 6mm BR [Norma], and others. Today’s highly-efficient calibers, such as 6mm BR and a host of newer developments might use 28-30 grains of powder to launch a 105-107gr match bullet at speeds approaching the .243 Winchester. The .243 Win needs 40-45 grain charges at the same velocity.
Champion-level Long Range shooters need every ballistic edge feasible. They compete at a level where 1″ more or less drift in a wind change could make the difference between winning and losing. Shooters recognized this early on — the then-new .300 H&H Magnum quickly supplanted the .30-06 at the Wimbledon winner’s circle in the early days.
The .300 Winchester Magnum became popular, but its 190-220gr bullets had their work cut out for them once the 6.5-284 and its streamlined 140-142gr bullets arrived on the scene. The 6.5-284 gives superb accuracy and wind performance with about half the recoil of the big .30 magnums – albeit it is a known barrel-burner.
Currently, the 7mm Remington Short Action Ultra-Magnum (aka 7mm RSAUM), is giving stellar accuracy with cutting-edge, ~180 grain bullets, powder charges in the mid-50 grain range and velocities about 2800+ fps in long barrels. Beyond pure efficiency, the RSAUM’s modern, “short and fat” design helps ensure fine accuracy relative to older, longer cartridge designs of similar performance.
Recent design advances are yielding bullets with here-to-fore unheard-of ballistic efficiency; depending on the cartridge, they can make or break ones decision. Ballistic coefficients (“BC” — a numerical expression of a bullet’s ballistic efficiency) are soaring to new heights, and there are many exciting new avenues to explore.
The ideal choice [involves a] balancing act between bullet BCs, case capacity, velocity, barrel life, and recoil. But, as with new-car decisions, choosing can be half the fun!
Factors to Consider When Evaluating Cartridges
For competitive shooters… pristine accuracy and ballistic performance in the wind are critical. Flat trajectory benefits the hunter who may shoot at long, unknown distances (nowadays, range-finders help). However, this is of much less importance to competitors firing at known distances.
Recoil is an issue, particularly when one fires long strings during competition, and/or multiple strings in a day. Its effects are cumulative; cartridges with medium/heavy recoil can lead to shooter fatigue, disturbance of the shooting position and lower scores.
For hunters, who may only fire a few shots a year, recoil that does not induce flinching during sight-in, practice and hunting is a deciding factor. Depending on their game and ranges, etc., they may accept more recoil than the high-volume High Power or Long Range competitor.
Likewise, throat erosion/barrel life is important to competitive shooters, who fire thousands of rounds in practice and matches, vs. the medium/big game hunter. A cartridge that performs well ballistically with great accuracy, has long barrel life and low recoil is the competitive shooter’s ideal. For the hunter, other factors may weigh more heavily.
Cartridge Efficiency and Energy — Another Perspective
Former Lapua staffer Kevin Thomas explains that efficiency can be evaluated in terms of energy:
“Cartridge efficiency is pretty straight forward — energy in vs. energy out. Most modern single-based propellants run around 178-215 ft/lbs of energy per grain. These figures give the energy potential that you’re loading into the rifle. The resulting kinetic energy transferred to the bullet will give you the efficiency of the round. Most cases operate at around 20-25% efficiency. This is just another way to evaluate the potential of a given cartridge. There’s a big difference between this and simply looking at max velocities produced by various cartridges.”

Amanda Elsenboss has won the 2023 NRA National High Power Rifle (Mumma Trophy) and Service Rifle (Dupont Trophy) Championships with a Grand Aggregate score of 2387-113X. Shooting at Camp Atterbury in Indiana, Elsenboss set a new Service Rifle record and also earned High Woman and High National Guard honors. Amanda was a member of the USAMU Team for many years and now serves in the National Guard. This is not Amanda’s first trip to the podium — she also won the NRA High Power Championship in 2021 shooting a service rifle in all matches (Read More HERE). And last year, Amanda won the prestigious President’s 100 Match at Camp Perry, the first woman in history to do so.
At the 2023 NRA National High Power Rifle Championships, held July 8-14th at Camp Atterbury Elsenboss triumphed over a strong field of 54 of the nation’s top service rifle competitors.
Here are Elsenboss’s individual 2023 Championship scores, event by event:
Grand Aggregate — 2387-113X
Erdman Trophy – 594-21X
Centenary Trophy – 596-28X
Nevada Trophy – 795-34X
Scott Trophy – 200-15X
Crescent Cup – 199-5X
Crowell Trophy – 199-11X
Marine Gunner DI Boyd II Memorial Trophy – 1190-49X
Vandenberg Cup – 796-40X
Clarke Trophy – 796-39X
In addition, Elsenboss, who shoots with Team Berger, was a member of the Veteran’s Family Brigade Anderson team, who won the RNDC Trophy team match with a 1985-93X score. Team members included: Samuel Freeman, Hugo Adelson, Julia Carlson, James Mauer (Captain), and Norman Anderson (Coach).
For her service rifle, Elsenboss used Berger .22 Cal 80.5gr Fullbore Target Rifle bullets and 77gr OTM Tactical Rifle bullets. Elsenboss will also be competing at the 2023 Civilian Marksmanship Program (CMP) National Rifle Matches at Camp Perry.

Is your well-built rifle of high-quality components plagued with vertical fliers across more than 1-3 handload combinations? Consider the bedding, crown and scope/sight mounts. Are they correct? If so, then you might check for ignition issues before boldly undertaking an extensive, expensive, and quite possibly fruitless quest for the “magic handload”.

To 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.
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.”
