CMP Training Courses at National Matches This Summer

Camp Perry CMP instruction clinic

Ready to learn more about marksmanship? This summer, the CMP will offer a wide selection of training programs at the National Matches at Camp Perry. CMP training courses serve all levels of shooters, with personalized instruction for all. During this year’s National Matches, there will be an array of educational courses taught by experts, including USAMU team personnel and coaches. Courses span from junior to advanced, delivering a little something for everyone.

Participants in CMP National Matches clinics receive one-on-one instruction. Here is a quick guide (ranked from Advanced to Beginner) for scheduled learning events at the 2022 Camp Perry National Matches, which run July 12 through August 13, 2022.

ADVANCED – Team CMP Advanced Highpower Clinic:
Led by members of CMP Gold (CMP’s own competitive Highpower squad), the Advanced Highpower Clinic offers more complex instruction in service rifle competition techniques using classroom and range discussion. Though the class traditionally utilizes only dry-fire training on the range, in 2021, a 600-yard live-fire portion was added. This course is only open to those who have attended the Advanced Small Arms Firing School at least once and have an “Expert” classification with the CMP or National Rifle Association.

The Advanced High Power Clinic, led by Team CMP members including Bob Gil (above), provides advanced training on wind reading, mental management and more.

INTERMEDIATE/ADVANCED – Junior Smallbore and Air Rifle Camp:
The camp is open to intermediate and advanced junior athletes who shoot both three-position smallbore and standing or international air rifle. Instruction is held on CMP’s outdoor Petrarca Range and within the Gary Anderson CMP Competition Center indoor air range, both located on the grounds of Camp Perry. Participants must be between the ages of 12 to 20 and currently involved in three-position smallbore competition matches and international air rifle. Camp will cover safety and a reinforced understanding of the fundamentals, among several other points of interest. Those juniors hoping to move their marksmanship careers on to college are encouraged to sign up for this valuable course.

INTERMEDIATE – U.S. Marine Corps Junior Highpower Clinic:
The three-day clinic gives focus to more advanced training outside of fundamentals, including weather conditions, how to read wind, equipment use, shooting positions and rulebook standards. Juniors in the clinic spend one day in the classroom, followed by two days of live-fire on the range at 200, 300 and 600 yards. Those young athletes who would like to attend this clinic must first attend the Rifle Small Arms Firing School.

BEGINNER – Small Arms Firing Schools (SAFS):
One of the most popular events of the National Matches, the SAFS course is a combination of classroom education and hands-on instruction on fundamentals, competition basics and safety. Training is led by members of military marksmanship teams as well as certified CMP instructors. At the conclusion of the course, students fire real competitions on the range, with instructors nearby. Equipment is provided by the CMP, with participants only needing a willingness to learn in order to attend. Currently, the CMP offers Small Arms Firing Schools for Pistol (M9), Smallbore Rifle, .22 caliber Rimfire Sporter Rifle and Highpower Rifle (M16) during the National Matches as well as an Advanced SAFS course for further training.

BEGINNER — As-Issued Military Rifle Clinics:
Any CMP Games competitors who have not previously fired in one of these matches are required to attend a clinic before they fire. All other competitors in these matches are encouraged to attend as well. These free one-hour clinics will cover the Garand-Springfield-Vintage Matches with instruction and demonstrations. Topics include match rules, shooting positions and techniques, scoring and pit pulling procedures and how to fire the courses of fire. The clinic is open to all competitors. More experienced juniors may attend the USMC clinic, taught by current marksmanship professionals.

BEGINNER — M1 Maintenance Clinic:
CMP Armorers will present this two-hour clinic on disassembly, assembly and maintenance of the M1 Garand Rifle. Special attention will be given to accurizing steps that can be taken with the rifle while maintaining its legality for CMP-sanctioned As-Issued Military Rifle Matches. Topics such as head space, barrel installation, component purpose/function, general rifle assembly, rifle/component maintenance and various other techniques will be covered during the course.

Optimal Barrel Twist Rate — Factors to Consider

Glen Zediker Twist Rate .223 Rem Barrel Top Grade Ammo Midsouth
Here’s an extreme range of .224-Caliber bullets: 35gr varmint bullet and 90gr match bullet. Of course, along with bullet length/design, you need to consider MV when choosing twist rate.

Even with the same caliber (and same bullet weight), different bullet types may require different rates of spin to stabilize properly. The bullet’s initial spin rate (RPM) is a function of the bullet’s muzzle velocity and the spin imparted by the rifling in the barrel. You want to ensure your bullet is stable throughout flight. It is better to have too much spin than too little, according to many ballistics experts, including Bryan Litz of Applied Ballistics. The late Glen Zediker put together some basic tips concerning barrel twist rates and bullet stability. These come from Glen’s book, Top Grade Ammo.

Choosing the Right Twist Rate
I’d always rather have a twist too fast than not fast enough. Generally… I recommend erring toward the faster side of a barrel twist decision. 1:8″ twist is becoming a “new standard” for .224 caliber, replacing 1:9″ in the process. The reason is that new bullets tend to be bigger rather than smaller. Don’t let a too-slow twist limit your capacity to [achieve] better long-range performance.

Base your next barrel twist rate decision on the longest, heaviest bullets you choose to use, and at the same time realize that the rate you choose will in turn limit your bullet choices. If the longest, heaviest bullet you’ll shoot (ever) is a 55-grain .224, then there’s honestly no reason not to use a 1:12″. Likewise true for .308-caliber: unless you’re going over 200-grain bullet weight, a 1:10″ will perform perfectly well.

Bullet Length is More Critical than Weight
Bullet length, not weight, [primarily] determines how much rotation is necessary for stability. Twist rate suggestions, though, are most usually given with respect to bullet weight, but that’s more of a generality for convenience’s sake, I think. The reason is that with the introduction of higher-ballistic-coefficient bullet designs, which are longer than conventional forms, it is easily possible to have two same-weight bullets that won’t both stabilize from the same twist rate.

Evidence of Instability
The tell-tale for an unstable (wobbling or tumbling) bullet is an oblong hole in the target paper, a “keyhole,” and that means the bullet contacted the target at some attitude other than nose-first.

Glen Zediker Twist Rate .223 Rem Barrel Top Grade Ammo MidsouthIncreasing Barrel Length Can Deliver More Velocity, But That May Still Not Provide Enough Stability if the Twist Rate Is Too Slow

Bullet speed and barrel length have an influence on bullet stability, and a higher muzzle velocity through a longer tube will bring on more effect from the twist, but it’s a little too edgy if a particular bullet stabilizes only when running maximum velocity.

My failed 90-grain .224 experiment is a good example of that: I could get them asleep in a 1:7″ twist, 25-inch barrel, which was chambered in .22 PPC, but could not get them stabilized in a 20-inch 1:7″ .223 Rem. The answer always is to get a twist that’s correct.

These tips were adapted from Glen’s popular 2016 book, Top-Grade Ammo, now $38.95 on Amazon. That work has numerous helpful articles on technical topics. Here are links to this title and other books by Glen Zediker.
