Story based on article by Gary Anderson, DCM Emeritus
Updated rules governing CMP Competitions in 2024 have been posted on the CMP website. Competitors and match officials may download these new rules for the 2024 competition season. The CMP currently produces seven different competition rulebooks. Six of these rulebooks have been revised and are now available as New Rulebooks for 2024, listed below.
Links to electronic versions of each 2024 rulebook may be uploaded onto electronic devices for everyday access, or they can be printed as hard copies to be kept in notebooks. Printed versions of these rulebooks will be published in a couple of months for those who prefer traditional rulebook hard copy formats. However the electronic version of the rule posted on the website will still be the official version of the rule.
Magazine Rule Updates for AR and M1A Rifles
The 2024 rules will permit M16/AR15-type rifles as well as M14/M1A-type rifles to have shorter 5- and 10-round magazines. This will help shooters who compete in states with restrictive magazine laws.
NOTE: Competitors who plan to take advantage of this rule change need to be aware that shorter rifle magazines must have visible, brightly colored strips on the bottom of the magazine (see photo). This is so Range Officers can readily see when these magazines are inserted or removed.
New Categories for Vintage Sniper Rifle Team Matches
One notable 2024 rule change is the addition of a new rifle category for the Vintage Sniper Rifle Team Match. This will allow two-person teams to compete with sniper rifles produced between 1954 and 1976, during the Viet Nam era. See “Guidelines for Preparing Vintage Sniper Rifles that Comply with Class B Viet Nam Era Vintage Sniper Rifle Rules”, now included with the CMP Games Rulebook for the Vintage Sniper Rifle Team Match.
Distinguished Marksman Program for Shooters with Disabilities
One of the newer CMP programs is the Distinguished Marksman Program that offers opportunities for competitors with disabilities to use adaptive positions and equipment to complete EIC courses of fire. Each rulebook provides specific rules for how competitors with disabilities or limitations can earn Distinguished Marksman EIC credit points. Persons with disabilities who have an interest in marksmanship should definitely consider this program. Interested persons should contact Amy Cantu at 888-267-0796 (toll-free) or via email at: acantu@thecmp.org.
All of the Range Officer scripts that were previously published in the back of the CMP rulebooks have been taken out of this year’s rulebooks. These Range Officer scripts are still accessible through the rulebook postings in the CMP website. Links to the “Range Officer Firing Procedures” for each discipline are posted with the rulebook listing. Each Range Officer script can be downloaded in a format that accommodates their use on the range. This will eliminate several dozen pages from the rulebooks while ensuring that Range Officers still have full access to the range procedures and Range Officer instructions.

It’s easy to think about shooting your first precision rifle match and worry about all of the gear and trinkets that you may need to make it through. In reality, the old rules apply — keep it simple.
We wanted to put together for you a no-nonsense list of the Top Five Gear Items you need for your first match. This list focuses on the “must-have” items you’ll need for PRS-Style competitions.
1. A Rifle (That is Reliable and Sub-MOA Accurate)
Your rifle is the most obvious piece of kit, but we can give you a little more information. Most of the guys you’ll find out there are shooting 6.5 Creedmoor. Yeah, there are guys using .308 Wins and 6mm Dashers, but the 6.5 Creedmoor makes up more than half of the rounds shot in PRS competition, when looking at both national and club matches. Your comp rig needs to be mag-fed and shoot better than 1 MOA. It DOESN’T need to be better than 0.5 MOA (half-MOA). With most targets being 2-3 MOA in size, a half-MOA gun will do just fine. More accuracy is better of course, but you don’t need an exotic quarter-MOA rig to win.
[Editor’s NOTE: PRS does offer a Gas Gun division, but most guys start out with a bolt-action rifle, which will be less maintenance-intensive than an AR-platform rig.]
Muzzle brakes, like our Area 419 Hellfire, are also very popular as much of the PRS game is recoil management. If you can’t see your misses, you’re sure to have more of them.
The rifle also needs an optic with repeatable clicks and a reticle with Mil- or MOA-based hashmarks. The clicks can be either Mil system or MOA system (Mil is more common), so long as the click values match the reticle (i.e. you don’t want 1/4-moa clicks with a Mil-marked reticle). How much power do you need? Anything that zooms in the mid-teens will suffice. I could shoot a match with a fixed 12X scope and not feel disadvantaged. We love the Kahles K624i, if you’re looking for a suggestion.
Oh, and you’ll want a bipod — but the choice in bipod deserves a whole separate article by itself. Nothing wrong with starting out with a Harris swivel. Then you might look at different bipods on other competitors’ rifles for comparison.
2. Ammunition — Factory Ammo and Hand-loads
Good ammo is important, but as we discuss above, 0.5 MOA is good enough. Also, speed is great but it matters FAR less than you’d think. Drop can be calculated with precision, and distances are normally known, so a slightly flatter trajectory doesn’t really matter. Wind matters, but the difference you’ll find when eeking out that last 50 fps is very, very small.
Federal, Hornady, and Prime all make quality ammo that is widely used by shooters from local to national matches. Facebook photo by CReece.
Precision Handloads
If you want to run down the rabbit hole of finding that perfect ammo that shoots in the “twos” (0.2 MOA), get yourself an AutoTrickler and some of our billet aluminum accessories — you’ll love the setup.
3. A Versatile Support Bag
There are countless bag options. But there is ONE bag you’ll see everywhere, and for good reason. The Game-Changer from Armageddon Gear is aptly named. Many shooters use it as a barricade bag as well as a rear bag, meaning a guy could get away with using only this bag for an entire match. If you need another bag when you get there, ask someone in your squad, they’ll share. I promise.
4. Ballistics Calculator APP
All PRS/NRL shooters need reliable and accurate ballistic solutions. The software-enabled Kestrel is a very common item on the range, but you’ll also see lots of guys using mobile Apps such as Shooter or Applied Ballistics Mobile, and they have great results.
It’s also handy to have an armband or an item like the Hawk Hill data card holder for stages with various targets at differing ranges. Once the RO says “engage” and your mind stops working, you’ll appreciate having it written down.
5. Hearing Protection
PRS Competitors shoot with brakes and sometimes in enclosed spaces. That’s why you need serious hearing protection. We recommend NRR 33 earplugs, doubled up with Electronic Muffs to hear range commands. I have used the 33 dB NRR Mack’s foamies at matches for most of the last year, and the Howard Leight NRR 33 Max-1s are also very effective. The budget-priced (under $55) Howard Leight Impact Sport Electronic muffs work well, but premium electronic muffs may be more comfortable.
Growing in popularity are high-tech, in-ear digital units like the ESP Stealth. I have a set of linked ESP Steaths on the way and hope to evaluate them soon. These are supposed to be very good, but the ESP Stealths cost $2100.00 per pair!

RCBS has released a special, limited-edition red, white and blue version of its popular Summit press to celebrate 10 years of the unique, small-footprint Summit. We have used RCBS Summit presses extensively and they has performed great, both in the shop and at the range. One of our testers even adapted his green Summit press to fit to a trailer hitch (see end of article).
The Summit single-stage reloading press has a cast iron frame surrounding a polished steel ram for smooth operation. The Summit’s unique C-Frame design allows it to be mounted virtually anywhere on your bench while being easily manipulated by both right- and left-handed users. With a 4.5″ opening, you have great full frontal access to your cases as there is no frame to obstruct your hands. Plus the Summit can be placed anywhere on your bench as there is no linkage below the press. And the shell-holder is stationary on the base making visual confirmation of powder charge level easy.
The Summit Press works with standard 7/8″-14 threaded dies, or 1-1/4″-12 with the reducing bushing removed. The ambidextrous design allows easy use by both right and left-handed loaders and the zero fitting ensures you can keep the press lubricated with your favorite lubricant.
Only 1,000 units of the Summit single-stage press will be made in the special red, white and blue Freedom Camo finish, making this 10th-anniversary run of presses instantly identifiable. The 10th Anniversary Summit Press comes with the short handle and features a tri-color Freedom Camo die plate. “The Summit Press has been a staple in our assortment for a decade,” said Justin Smith, RCBS Product Manager. “We wanted to do something special to mark 10 years of the Summit Press, and we thought making a red, white and blue Freedom Camo version … would be a fun way to do it.”
Like its classic green older brother, the 10th Anniversary Summit press readily accepts standard 7/8″-14 threaded dies for a wide range of cartridges, as well as 1-1/4″-12 threaded dies with the reducing bushing removed. CLICK HERE to learn more about the Summit Press, including the special 10th Anniversary edition. Currently you can order direct from RCBS for $379.99, but we expect other vendors to offer this 10th Anniversary Summit for considerably less.
RCBS Summit Mounted on Trailer Hitch For Loading Anywhere — No Bench Required
You may have heard the phrase “blueprinting an action”, but do you know what that really means? Do you know what operations are done to an action during the blueprinting process? To help you understand, gunsmith Bill Marr of RifleShooter.com has created a helpful article showing a Rem 700 blueprinting job start to finish. This article spotlights how the procedures can be done with manual tools. Bill, who runs 782 Custom Gunworks Ltd., can also perform many of these operations with modern automated machinery. In fact, Bill has written a follow-up article on Truing a Rem 700 receiver with a Lathe.
Bill explains: “Blue-printing, or truing a rifle action, ensures the receiver face, threads, lugs, bolt lugs, and bolt face are square to the center line of the receiver.” In Bill’s informative article, Bill shows how he blueprints a Remington 700 short action receiver with .308 Win bolt face. He covers the following procedures step by step:
Action Disassembly
Ream Minor Diameter of Receiver Threads
Square the Receiver Lugs
Square the Face of the Receiver
Lap the Bolt Lugs
Square the Bolt Face
We use the bushings to guide the receiver tap. This chases the threads and ensures they are square.
2. Truing the Receiver Face
Using the receiver facing tool, the front of the receiver is trued. The tool is placed over the tap and turned by hand. We used Do Drill to lubricate it.
3. Lapping the Lugs
The bolt lapping tool screws into the front of the action and applies rearward pressure on the bolt face. A little bit of lapping compound is placed on the front of the receiver lugs. The bolt handle is then raised and lowered repeatedly. Note — it is critical that we do not get any lapping compound on any other surfaces.
4. Truing the Bolt Face
On this bolt, the central part of the bolt face was low. After the truing operation, this Rem 700 bolt face is now completely square to the action.
IMPORTANT: Rifleshooter.com states: “This article highlights our project and is presented for information purposes only. This provides an overview of the process and should not be attempted without the guidance and supervision of an experienced gunsmith“.

Every year the NRA Publications group announces Golden Bullseye Award winners for various product categories (rifle, handgun, shotgun, optics, gear etc.). These awards are like the Oscars for the shooting industry. There are many Golden Bullseyes given out each year because there are separate awards given by different NRA Magazines — including American Rifleman, Shooting Illustrated, and American Hunter. Here are the 2024 Rifles of the Year (Golden Bullseye Winners) as chosen by each of those three publications.
American Rifleman 2024 Golden Bullseye — Rifle of the Year
American Rifleman says the Springfield Armory 2020 Rimfire has impressive features: “Springfield 2020 Rimfire rifles come with an accuracy guarantee to shoot a three-shot group under one inch at 50 yards with match-grade ammunition. [The] new 2020 Rimfire bolt action [has] dual cocking cams and a 60-degree bolt throw. Rifles come supplied with an interrupted Picatinny optics rail[.] The trigger is user-adjustable [and is] compatible with 700-pattern aftermarket triggers[.] The rifle is fed with a detachable-box rotary magazine with a 10-round capacity of the 10/22 pattern.”
American Hunter 2024 Golden Bullseye — Rifle of the Year
American Hunter magazine likes the Marlin 336 Classic, with its smooth lever action and traditional appearance: “A gorgeous lever-action … this is a firearm as comfortable over the fireplace as it is in the deer woods. Its American black walnut stock blends beautifully with the satin-blued finish of the receiver and barrel.”
Shooting Illustrated 2024 Golden Bullseye — Rifle of the Year
S&W’s M&P FPC folding carbine is easy to transport and has smart on-board storage for magazines.

.009″ — The Record That Stood for 40 Years.
In 1973 Mac McMillan shot an amazing 100-yard, .009″ five-shot group in a benchrest match. The .009″ group was measured with a 60x microscope for verification. Mac McMillan shot the group using a handbuilt prototype McMillan rifle with an early McMillan stock.
Mac’s .009″ group was the “Holy Grail” of rifle accuracy. This .009″ record was considered by many to be unbreakable, a record that would “stand for all time”. Well, it took 40 years, but someone finally broke Mac’s record with an even smaller group. In 2013, Mike Stinnett shot a .0077″ five-shot group using a 30 Stewart, a .30 caliber wildcat based on the 6.5 Grendel. Stinnett’s .0077″ group now stands as the smallest 100-yard group ever shot in registered benchrest competition.* Read About .0077″ group HERE.
Stinnett’s success doesn’t diminish the significance of Mac McMillan’s .009″ group in the history of benchrest competition. For four decades Mac’s group stood as the ultimate standard of rifle accuracy*. For those of you who have never seen Mac McMillan’s .009″ group, here it is, along with the NBRSA World Record certificate. The target now hangs in the McMillan Family Museum.
*Somebody else might claim a smaller group, but unless moving backers or electronic targets were used, it cannot be verified. Moving target backers are used at registered benchrest matches to ensure that five (5) shots are actually fired in each group. That eliminates any doubt.
This story features a unique, American-designed rimfire rifle, chambered for the potent .17 HMR round. The current generation Browning T-Bolt has a tang-mounted ambidextrous safety, a choice of barrel contours, lengths, and finishes, and a variety of stock options. What sets the T-Bolt apart from other rimfire rifles is the way the action cycles. There is not a conventional bolt that requires four distinct motions (lift bolt handle up/pull back/move forward/rotate handle down). With the T-Bolt you simply pull the handle straight back to extract a round, then return it forward to chamber a new round from the Double Helix magazine. The cocking effort is divided between back pull and forward movement so the effort is relatively light and easy.
Among current rimfire rifles, the Browning T-Bolt ranks high for fit and finish. The bluing is very nice and the T-Bolt even boasts a gold-plated trigger shoe. Many different stock types have been offered in recent years including some very nice AA Maple stock models as shown below (click to zoom). These T-Bolt rifles exhibit very fine craftmanship. Current models are made in Japan under license to Browning.

BARREL – Medium Sporter; Blued finish; Free-floating; Semi-match chamber; Recessed crown

T-Bolt Owner Talks about Function and Accuracy
“I have a Browning T-bolt in .17 HMR, but with the maple stock. It is probably my favorite .17 HMR rifle (also the most expensive). The rifle feels smaller than some of my other .17 HMR rifles. I think the length of pull is a little shorter. I do like the light weight and trim handling of the rifle and the straight-pull bolt can be cycled really quickly. Mine is quite accurate and will shoot one-inch groups at 100 yards with both Hornady ammo and the CCI A17 ammo.” — RexRay, Varminter.com Forum member.
Pros and Cons of the Browning T-Bolt
The T-Bolt has a reputation for good accuracy, provided you have a good lot of .17 HMR ammo (we recommend checking for bullet run-out before you shoot for groups). The straight-pull action works as advertised — it is fast, smooth, and easy-to-operate. The Double Helix magazine (covered below) is excellent. It is very compact yet ultra-reliable. Another plus is that the T-Bolt has been produced in many different versions, with a variety of stocks, and even a stainless action version.
What are the negatives? Some of the stocks have a somewhat short length-of-pull, but this is easily solved with spacers. The main complaint is the factory trigger — some owners say it is too heavy at about 4 pounds, though the break is clean. For varmint work, we could live with the stock trigger and put money saved into optics.
If you prefer a very light trigger, JARD makes a T-Bolt replacement trigger. Featuring an aluminum housing, the JARD T-Bolt trigger can be ordered with 12-, 16-, or 20-ounce pull weights. The JARD trigger offers a crisp, clean break significantly lighter than stock. But at $254.95 the JARD trigger is fairly expensive. Additionally there have been a couple complaints about slam fires at the lowest weights so we recommend the 20-ounce. Here is one owner review, from a Rimfire Central thread: “The new Browning T-Bolt is a great rifle in all aspects except for the trigger. In my case when I received my JARD trigger it was an almost drop-in installation with very little adjusting or fooling around. For me it made a decent little rifle a great little rifle.”
Browning Double Helix 10-Round Magazine
The T-Bolt’s patented 10-round rotary Double Helix™ magazine is a unique design that feeds very reliably and is easy to load. The Double Helix magazine uses a torsion drive spring and interlocking gear design to maintain correct timing and exact cartridge alignment for smooth, reliable feeding. The translucent gray body allows for easy verification of the number of remaining cartridges. We like the fact that the Double Helix provides TEN-round capacity while fitting nearly flush with the bottom of the action.
The Browning Double Helix rotary box magazine system is easy to load, easy to carry, and easy to use. The smooth, rounded exterior contours of the Double Helix, along with twin gripping grooves, tapered shape and a slightly extended baseplate design make insertion positive, while the spring-assisted drop-free magazine ejection feature allows for rapid magazine changes. T-bolt owners confirm that feeding and reliability is excellent — the magazine design puts cartridges in perfect alignment with the chamber.
Other Browning T-Bolt Variants
In recent years, Browning has produced T-Bolt rifles in a variety of models, with many different stock types and various barrel lengths/contours. Most of the photos above showcase the AA Maple Sporter T-Bolt, which is currently out of production, though still available from some dealers (if you search). We like the looks of the AA Maple T-Bolt, but there many other stock options including dark brown, Black, Green, and various camouflage finishes. Use the links below to see other T-Bolt configurations.
Current production T-Bolts are offered in four rimfire chamberings: .17 HMR, .22 LR, .22 Magnum, and .22 WMR. Barrel contours and lengths (from 2″ to 22″) vary from model to model. Shown below is the New-for-2024 T-Bolt Target SR (Suppressor Ready) and two other current models. Then we feature five notable discontinued T-Bolt rifle models. CLICK HERE to see all discontinued T-Bolt variants — many of which are still available if you search gun vendors.
.17 HMR Cartridge — Fast and Deadly on Small Varmints
We are big fans of the .17 HMR round. It’s just about perfect for ground squirrels, and is effective on prairie dogs out to about 200 yards. The three main .17 HMR producers have been CCI, Federal, and Hornady, but you will also see Browning and Remington .17 HMR ammo. Choose from 17gr or 20gr bullets — both work well in the varmint fields. A good source for all types of .17 HMR ammo is TargetSports USA.
Here is a Comparison Test of Multiple Types of .17 HMR Ammo
CCI .17 HMR TNT offers 2650 FPS Velocity
For varmint work we like CCI’s modern .17 HMR VNT ammo. This boasts class-leading 2650 FPS muzzle velocity. Engineered to combine good accuracy with high impact energy, this CCI TNT ammo features a 17gr polymer-tipped bullet designed for rapid expansion. We also like the Hornady .17 HMR Varmint Xpress ammo, rated at 2550 FPS with 17gr V-Max bullets.
Here is a video every shooter should watch. It reminds us that our sport demands 100% attention. Lose track of individuals down-range and the results could be tragic. This video will give you chills (starting at about the 0:25 mark). We need to remember to follow all the firearms safety rules, and apply them all the time. At the range, all it takes is one brief moment of inattention to create a life-threatening situation. Never assume the downrange area is safe. Use your own eyes and ears.
This video shows a competitor shooting a stage at an action pistol match. He starts when instructed by the Range Safety Officer (RSO). But unbeknownst to both RS0 and competitor, a volunteer is downrange working on targets. Watch carefully. At 0:27 the shooter sweeps left to right, engaging a paper silhouette target to his right. Then, at 0:30, as he begins a mag change, his head turns downrange. A few yards away is a white-shirted range worker! The shooter yells “Hey what’s going on?!”
What’s going on indeed… The RSO should have ensured that nobody was downrange before the shooter even stepped up to the firing line. If other competitors standing to the side had been alert, they might have seen the worker changing targets and called for a halt. And the target-worker himself — even if he was wearing earmuffs, he should have noticed that live fire had commenced just yards away…
We also have to wonder about the stage design. This set-up made it very difficult to see downrange. The white panels (see 0:10-0:20) definitely hid the target worker from view. In hindsight, given the way the stage was laid out, this was truly an “accident waiting to happen”. It’s fortunate that no one got injured in this incident. But this chilling video provides a lesson to all shooters — “Safety First”.
How could this “near-fatality” have been averted? Post your comments below.

In recent years, Browning has produced T-Bolt rifles in a variety of models, with many different stock types and various barrel lengths/contours. Most of the photos above showcase the AA Maple Sporter T-Bolt, which is currently out of production, though still available from some dealers (if you search). We like the looks of the AA Maple T-Bolt, but there many other stock options including dark brown, Black, Green, and various camouflage finishes. Use the links below to see other T-Bolt configurations.
