Mike Kurtz’s Competition Machine F1 “Pro-Mod” F-Open Rifle
Today’s Sunday GunDay article showcases a modern F-Open Rifle built on a Competition Machine Aluminum Chassis. This is quite a bit different than a typical F-Open rifle with a laminated wood or wood/carbon stock. But the rifle shoots extremely well, and has already won some mid-range F-Open matches.
The rifle’s owner, a highly respected vehicle mechanic, explained his objective with this rifle: “I wanted to build a second F-Open rifle to shoot primarily 600-yard Mid-Range and also serve as my back-up long range rifle. That way I can use the same brass, bullets, and primers. So it would be chambered in 7mm-6.5 PRC, the same as my other F-Open rifle. That rig is a 7mm-6.5 PRC with Cerus XR stock, BAT Neuvo action, and Bartlein 1:9-8.7″ gain-twist barrel. I absolutely love that rifle and it has achieved several top honors. But for this project, I wanted to try some different rifle components to see how they performed in this same caliber. So I decided to go with Brux barrels, BAT Neuvo aluminum action (but see below), and an Eliseo Competition Machine F1 aluminum alloy chassis.”
BARREL SPECIFICATIONS: I ordered two Brux 7mm x 33″ barrels with 1:8.5″ twist. The contour was supposed to be 1.350″ diameter for 5″, tapered-down to 1.150″ diameter at the muzzle end. However, when the barrels arrived they were tapered down to 1.050″, a bit smaller. The folks at Brux admitted the work order was mis-read and offered to take back the barrels and make me two more. Or, I could keep the barrels with nice discount. I contacted my gunsmith, Omar Alonzo, for his advice and he said to keep them, they would shoot just fine. That turned out to be a blessing because the total rifle weight is now just three ounces under 22 pounds with one of these barrels. Omar chambered it with his 7mm-6.5PRC “no-turn” reamer that was used on my Cerus rifle. The Brux barrel was finished at 32″ with the muzzle end threaded for a V2 tuner.
ACTION and TRIGGER: I intended to use an aluminum BAT Neuvo action because I anticipated weight may be a concern, but they were on back-order with no lead time in sight. So for now I went with a used steel BAT Model M, 1.47 Octagon action that I acquired via the AccurateShooter Forum marketplace. This is a RBLP Right Eject action with magnum bolt face and 20 MOA integral Picatinny rail. The trigger is a Bix’N Andy Competition also scored on the Forum, set at 3 ounces. [NOTE: I now have an aluminum Neuvo AL in my possession. However, the F1 rifle is shooting so well, I’ll save the aluminum Neuvo for a future build.]
STOCK and FINISH: When I was planning my second F-Open 7mm-6.5 PRC rifle build, Gary Eliseo’s F1 aluminum chassis was my immediate choice. I was already familiar with Gary’s products since I started out three years ago with a used 6BR-chambered R1 tube gun. I purchased it from a Forum member and I adapted it for Mid-Range F-Open very successfully. Being a long-time drag racer and fabricator piqued my interest in these aluminum chassis combos. I contacted Gary Eliseo at Competition Machine and ordered his F1 F-Open Chassis System with one of his custom-machined bedding blocks for the Bat M action I acquired off the Forum.

Turn-around time was just about eight weeks, including aligning and epoxying the action bedding block into the chassis. Gary Eliseo offers full custom Cerakote services for his customers but I had something else in mind so I had the chassis sent to me “raw”, i.e. with a bare aluminum finish. At first I thought about polishing some or all the entire chassis but that would be too high maintenance. I decided to go with anodizing as I have done in the past with many race car components. Anodizing is an electrochemical process that converts the metal surface into a decorative, very durable, corrosion-resistant, anodic oxide finish that’s pretty tough and looks great!. This finish is available in many colors and in clear.
While I was surfing the internet looking for some color/combo ideas I stumbled on a local custom anodizer who had dozens of some really wild and crazy anodizing patters and color mash-ups. I messaged Stephen @ Caustic Customs and told him about my project. He replied that his specialty is paint-ball guns and this would be his first long gun but, hey, it’s aluminum! I gave him all the pieces of my F1 chassis. There were a couple of his patterns I really liked so I asked his opinion which he thought might look best for my project. He replied why not both? So I instructed him take both patterns and “run with it”. The end result is the Icy-Hot blue/red finish as seen in the pictures.
It all came together at Alonzo’s Custom Rifles in Pasadena, Texas. Omar hand-lapped the action bedding block surface to smooth-out some tiny high spots. He then skim-bedded the action with an epoxy filler to make sure the action made 100% contact with the bedding block. Barrel chambering, action fitting, trigger tuning, and final assembly was performed by Omar.
I finished the rifle with a hydraulic recoil pad from Falcon Strike and Anarchy Outdoor’s Penguin Precision Grip. Gary designed the F1 to utilize AR15-style grips. The Falcon Strike pad is not as sexy as the R.A.D. unit I have on my Cerus-stocked rifle, but I think its recoil-absorbing performance is up there with the R.A.D. unit. So, if a RAD is not in your budget or if weight is a concern, you can’t go wrong with a Falcon Strike recoil pad.
SCOPE/RINGS: My intention was to switch my March-X 8-80x56mm Majesta High Master scope between my two rifles. However the hefty stainless Bat M action nixed that idea. So to ensure the new rifle would be F-Open legal weight I went with a used March-X 10-60x56mm High Master scope that I acquired through the AccurateShooter Forum Marketplace. That 10-60X March, shown in the video, is almost 11 oz. lighter that my 8-80X March-X Majesta HM. NOTE: In some of the photos here, the rifle is fitted with an older March 8-80X scope (NOT the latest Majesta). The rings are March Superlight Titanium Ghost Rings — under 5 oz. for the set, the lightest I could find.

CARTRIDGE COMPONENTS and LOADING METHOD: I use Lapua 6.5 PRC brass, Berger 180gr Hybrid bullets and Federal 210M primers. New brass necks are expanded to 7mm and skim-turned to get a consistent .014″ neck thickness. I use a 35-degree cutter and go just a slight bit into the shoulder to ward off donuts. I then chamfer the flash holes, uniform the primer pockets, full-length size the cases, then expand and trim/chamfer the necks. My fired brass gets annealed, wet-tumble cleaned, full-length sized/expanded, and trimmed in that order. Bullets are pointed and then sorted by OAL. Primers are sorted by height and then by weight. I apply Neo-Lube to the inside of the necks with a foam Q-Tip for consistent seating psi.
This is from a 600-yard match shot with the F1 rifle a few months ago. Despite a strong wind from behind constantly switching right to left, I scored a 200-12X — good enough for Second Place.
LOAD DEVELOPMENT PROCESS: Thanks to some good 7mm-6.5 PRC load data posted on AccurateShooter.com, it helped me with a starting point to find a nice velocity node at 2865 fps using Hodgdon H4350. I did this by shooting some 2-shot groups seated .010″ off the lands. my focus was to find a node where the velocity leveled-out in at least two 0.5 grain increments in the 2850-2880 fps range. I then did a seating depth test at 100 yards to find my ideal seating depth which ended up at .024″ jumped. Next, I did some 3-shot groups at 100 yards to dial-in he barrel tuner until I got at least two consecutive ultra-tight groups. I verified that setting with a one-hole, three-shot group.

The Pew Pew Tactical website has interesting article on rifle and pistol cartridges and bullet types. This contains a large selection of interesting photographs and illustrations. If you load and/or shoot for a wide variety of cartridge types, you’ll find that article well worth reading. It has nearly 50 photographs and more than a dozen short videos. READ FULL Article.
The article also shows all types of pistol bullets, along with a variety of rifle projectiles. It even illustrates multiple types of shotshell cartridges.
The article also explains the basic components of modern cartridges — bullet, case, powder, and primer:

Popular Cartridge Types Profiled
The article provides quick summaries of popular ammunition types including 9mm Luger (9x19mm), .357 Magnum, .40 SW, .45 ACP, .223 Rem, and .308 Winchester. The author’s favorite pistol round is the 9mm Luger: “9mm is my personal favorite and if there was a “Goldilocks” round, this would be it. The very first gun I bought was a 9mm. They’re fun at the range. They’re good for defense. It is the standard round for NATO countries and the majority of police forces around the world. It is mild shooting, can vary in weight from 115 to 147 grains, and has varying stopping power based on the type of bullet.”
This Pew-Pew Tactical guide to cartridge types also provides a quick explanation of cartridge ignition — both centerfire and rimfire: “The rimfire’s primer is built into the rim while the centerfire cartridge has the primer in the center. Pro tip — if you can see a circle in the middle…it’s a centerfire cartridge.”
There are two common types of centerfire primers — Boxer and Berdan. This helpful Wikipedia illustration shows how Boxer, Berdan, and rimfire primers ignite the powder in the cartridge:

Every shooter should have a good rimfire rifle, both for fun shooting and for training. The .22 LR is very affordable to shoot, and the more potent .17 HMR and .22 WMR rounds also are great for small varmints out to 200 yards or so. Among the rimfire rifle makers, the Czech manufacturer CZ (Česká Zbrojovka) has been a world leader for many decades. In today’s Video round-up we feature a variety of CZ rimfire rifles including the the all-new CZ 457, the versatile CZ 455 VPT, and the classic CZ 452. We also include one semi-auto, the CZ 512 in .22 Winchester Magnum Rimfire (WMR).
New Generation CZ 457 with Upgrades
The CZ 457 may be the most modular precision rimfire on the market. You can swap barrels and magazines easily. The interchangeable barrel feature is by far the best feature of the CZ 457. Want to shoot .22 WMR for varmint hunts then transition to a .22 LR for precision shooting? No problem — five minutes and four screws are all you need. The CZ 457 is also an excellent value — it’s WAY better than a 10/22 but a fraction of the cost of high-end custom rimfire rigs. In the second video below, the CZ 457 goes head to head
In this video, Josh of Pursuit of Accuracy drives nails at 100 yards with his CZ 457:
And here Josh comparison-tests his Lilja-barreled CZ 457 head-to-head with the much more expensive Vudoo V22. The results may surprise you.
CZ 457 MTR Varmint — Product Showcase and Review
We really like the relatively new CZ 457 Varmint MTR .22 LR rifle. Along with other CZ 457 models, the MTR (“Match Target Rifle) Varmint features a completely new action that runs very smoothly with shorter bolt throw. The new 457s also have an American-style, push-to-fire safety. The new-generation actions have been trimmed back nearly one-inch in length, and slab-sided to reduce the footprint and weight of the actions. CZ ditched the 90º bolt rotation of the past in favor of 60º rotation. This change provides more room between bolt handle and scope for easier cycling of rounds. It also allows for the use of scopes with larger ocular bell diameters and lower ring heights.
The well-designed MTR stock has good ergonomics and nice stippling on the grip and fore-end. We were pleased to note that, with the 457 series, CZ is once again offering steel magazines that are interchangeable with older 452/455 magazines.
Here our friends at Area 419 offer a side-by-side comparison between a $2300+ rifle with Vudoo V-22 action in Manners stock and the $752.00 CZ 457. On a bang-for-the-buck basis, the CZ wins hands down. However, the Vudoo V-22 does offer centerfire-style action cycle, which helps with training. It also can run Rem 700-compatible triggers.
CZ 457 Royal Model — Handsome and Very Accurate
Above is a British review of the CZ 457 “Royal” model. This features a premium-grade Turkish walnut stock with contrasting dark fore-end tip. This rimfire rig is offered for $779.99 in the USA. CLICK HERE for a detailed written review on ShootingTimes.com. The Shooting Times’ test rifle showed very impressive accuracy with Lapua and SK Match ammo, with average 5-shot 50-yard groups under one half inch (Lapua Midas+ 0.41″; SK Long-range Match, 0.39″). SEE Full Test Results table.
CZ 455 Varmint Precision Trainer in Manners Stock
Rimfire cross-training allows PRS competitors to build their skill sets without breaking the bank (or burning out barrels). One great .22 LR option for cross-training is the CZ 455. The TFBTV video below spotlights the CZ 455 Varmint Precision Trainer (VPT), a smooth-running .22 LR bolt action. This factory rifle (now superseded by the CZ 457) was designed specifically as a training tool for precision long-range competition. It boasts a Manners composite stock and 20.5 or 24-inch heavy barrel. The 0.866″-diameter tube is threaded and suppressor-ready. The model 455 VPT is mag-fed and comes with a crisp trigger that adjusts to two pounds. If you can find one, expect to pay about $850 but you’re getting a premium Manners stock that originally cost $534 by itself.

CZ 452 — Classic Bolt-Action Rimfire Rifle
The CZ 452 is an affordable classic. It is ultra-reliable, easy to clean and maintain, and you’ll find very good examples on the used market for under $400. This is an excellent first rifle for a young family member. In this video, The TFB TV team tests a CZ 452-2E fitted with a suppressor. As the 452 series is being replaced, if you want to buy a new 2019 CZ 452, you’ll need to spend big bucks on the Grand Finale model: “Produced in limited quantity, the 452 Grand Finale (MSRP $1189.00) is a last hurrah to the venerable CZ 452. Built using the last 452 actions ever produced, on the original manual barrelling equipment and at the Brno workshop, the Grand Finale [features] hand-engraved scroll-work on the action, barrel, bottom metal and scope rings. The upgraded American walnut is trimmed with an ebony fore-end and grip cap.”
Semi-Auto CZ — Model 512 American in .22 Magnum Rimfire
The folks at Varminter.com are avid varmint hunters, who test varmint rigs in the real world, seeing how they perform in the varmint fields. Varminter.com was quite impressed with the CZ Model 512 American semi-auto .22 WMR (Winchester Magnum Rimfire) rifle. The testers found the Model 512 to be accurate, extremely reliable, and fun to shoot. Watch the video to field tests conducted in California. This self-loading rifle performed ultra-effective on California ground squirrels. Erik Mayer, Varminter.com’s publisher says: “The 22 Magnum (.22 WMR) is beginning to see a resurgence of sorts, as the rimfire ammunition becomes more readily available. Because of this, rifles like the CZ Model 512 have also begun to see a rise in interest again”. CLICK HERE for FULL REPORT with accuracy findings for multiple ammo types.

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.)

About Gary Anderson Gary Anderson served as the Director of the Civilian Marksmanship Program (CMP) from 1999-2009, and is now DCM Emeritus. As a Nebraska farmboy, Gary grew up hunting and shooting. Dreams of winning an Olympic Gold Medal in shooting led Gary to the U.S. Army. In 1959, he joined the elite U.S. Army Marksmanship Unit. Just two years later, he won his first national championship.
At the 1962 World Shooting Championships in Egypt, Anderson stunned the shooting world by winning four individual titles and setting three new world records. At the 1964 Tokyo Olympics, Gary won the 300m free-rifle Gold Medal, setting a new world record in the process. At the 1966 World Shooting Championships in Germany, Anderson won three additional world titles. At the 1968 Olympics, Gary won a second gold medal in the 300m free-rifle event.
After his “retirement” from international competition, Gary competed in the National High Power Championships, winning the President’s National Trophy in 1973, 1975 and 1976. Over his competitive career, Anderson won two Olympic Gold Medals, seven World Championships, and sixteen National Championships. He is unquestionably one of the greatest American marksmen ever.
In the archives of The First Shot (the CMP’s Online Magazine), SGT Walter E. Craig of the USAMU discusses physical conditioning for competitive shooters, particularly High Power competitors. Fitness training is an important subject that, curiously, is rarely featured in the shooting sports media. We seem to focus on hardware, or esoteric details of cartridge reloading. Yet physical fitness also matters, particularly for High Power shooters. In his article, Craig advocates: 1) weight training to strengthen the Skeletal Muscle System; 2) exercises to build endurance and stamina; and 3) cardiovascular conditioning programs to allow the shooter to remain relaxed with a controlled heart beat.
SGT Craig explains: “An individual would not enter a long distance race without first spending many hours conditioning his/her body. One should apply the same conditioning philosophy to [shooting]. Physical conditioning to improve shooting skills will result in better shooting performance[.] The objective of an individual physical training program is to condition the muscles, heart, and lungs thereby increasing the shooter’s capability of controlling the body and rifle for sustained periods.”
In addition to weight training and cardio workouts (which can be done in a gym), SGT Craig advocates “some kind of holding drill… to develop the muscles necessary for holding a rifle for extended periods.”
For those with range access, Craig recommends a blind standing exercise: “This exercise consists of dry-firing one round, then live-firing one round, at a 200-yard standard SR target. For those who have access only to a 100-yard range, reduced targets will work as well. Begin the exercise with a timer set for 50 minutes. Dry-fire one round, then fire one live round and without looking at the actual impact, plot a call in a data book. Continue the dry fire/live fire sequence for 20 rounds, plotting after each round. After firing is complete, compare the data book to the target. If your zero and position are solid, the plots should resemble the target. As the training days add up and your zero is refined, the groups will shrink and move to the center.”
Fitness training and holding drills help position shooters reach their full potential. Here is 6-Time U.S. National Long Range Champion John Whidden.
Training for Older Shooters
Tom Alves has written an excellent article A Suggested Training Approach for Older Shooters. This article discusses appropriate low-impact training methods for older shooters. Tom explains: “Many of the articles you will read in books about position shooting and the one mentioned above 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 30s 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 may be the recommended approach for younger folks, it may be totally inappropriate for older people.”
Barrel-maker Dan Lilja’s website, RifleBarrels.com has an excellent FAQ page that contains a wealth of useful information. On the Lilja FAQ Page you’ll find answers to many commonly-asked questions. For example, Dan’s FAQ addresses the question of barrel life. Dan looks at factors that affect barrel longevity, and provides some predictions for barrel life, based on caliber, chambering, and intended use.
NOTE: This article was very well-received when it was first published. We are reprising it for the benefit of readers who missed it the first time.
Dan cautions that “Predicting barrel life is a complicated, highly variable subject — there is not a simple answer. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy.” Dan also notes that barrels can wear prematurely from heat: “Any fast varmint-type cartridge can burn out a barrel in just a few hundred rounds if those rounds are shot one after another without letting the barrel cool between groups.”
Q. What Barrel Life, in number of rounds fired, can I expect from my new barrel?
A: That is a good question, asked often by our customers. But again there is not a simple answer. In my opinion there are two distinct types of barrel life. Accurate barrel life is probably the type most of us are referencing when we ask the question. But there is also absolute barrel life too. That is the point where a barrel will no longer stabilize a bullet and accuracy is wild. The benchrest shooter and to a lesser extent other target shooters are looking at accurate barrel life only when asking this question. To a benchrest shooter firing in matches where group size is the only measure of precision, accuracy is everything. But to a score shooter firing at a target, or bull, that is larger than the potential group size of the rifle, it is less important. And to the varmint hunter shooting prairie dog-size animals, the difference between a .25 MOA rifle or one that has dropped in accuracy to .5 MOA may not be noticeable in the field.
The big enemy to barrel life is heat. A barrel looses most of its accuracy due to erosion of the throat area of the barrel. Although wear on the crown from cleaning can cause problems too. The throat erosion is accelerated by heat. Any fast varmint-type cartridge can burn out a barrel in just a few hundred rounds if those rounds are shot one after another without letting the barrel cool between groups. A cartridge burning less powder will last longer or increasing the bore size for a given powder volume helps too. For example a .243 Winchester and a .308 Winchester both are based on the same case but the .308 will last longer because it has a larger bore.
And stainless steel barrels will last longer than chrome-moly barrels. This is due to the ability of stainless steel to resist heat erosion better than the chrome-moly steel.
Barrel Life Guidelines by Caliber and Cartridge Type
As a very rough rule of thumb I would say that with cartridges of .222 Remington size you could expect an accurate barrel life of 3000-4000 rounds. And varmint-type accuracy should be quite a bit longer than this.
For medium-size cartridges, such as the .308 Winchester, 7×57 and even the 25-06, 2000-3000 rounds of accurate life is reasonable.
Hot .224 caliber-type cartridges will not do as well, and 1000-2500 rounds is to be expected.
Bigger magnum hunting-type rounds will shoot from 1500-3000 accurate rounds. But the bigger 30-378 Weatherby types won’t do as well, being closer to the 1500-round figure.
These numbers are based on the use of stainless steel barrels. For chrome-moly barrels I would reduce these by roughly 20%.
The .17 and .50 calibers are rules unto themselves and I’m pressed to predict a figure.
The best life can be expected from the 22 long rifle (.22 LR) barrels with 5000-10,000 accurate rounds to be expected. We have in our shop one our drop-in Anschutz barrels that has 200,000 rounds through it and the shooter, a competitive small-bore shooter reported that it had just quit shooting.
Remember that predicting barrel life is a complicated, highly variable subject. You are the best judge of this with your particular barrel. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy.
Benchrest Barrel Life — You May Be Surprised
I thought it might be interesting to point out a few exceptional Aggregates that I’ve fired with 6PPC benchrest rifles with barrels that had thousands of rounds through them. I know benchrest shooters that would never fire barrels with over 1500 shots fired in them in registered benchrest matches.
I fired my smallest 100-yard 5-shot Aggregate ever in 1992 at a registered benchrest match in Lewiston, Idaho. It was a .1558″ aggregate fired in the Heavy Varmint class. And that barrel had about 2100 rounds through it at the time.
Another good aggregate was fired at the 1997 NBRSA Nationals in Phoenix, Arizona during the 200-yard Light Varmint event. I placed second at this yardage with a 6PPC barrel that had over 2700 rounds through it at the time. I retired this barrel after that match because it had started to copper-foul quite a bit. But accuracy was still good.
We talked with the experts at Bartlein Barrels. They confirmed that they have seen many, many more barrels harmed by crown damage caused by improper cleaning than by anything else. If you use a bronze brush, Bartlein recommends that you REMOVE the BRUSH after it passes through the muzzle. This is because the bristles take a set (pointing to the breech) during the out-stroke. In other words the bristles angle back as you push towards the muzzle from the breech. If you drag the brush backwards at the muzzle, you force these bristles to reverse direction abruptly right as they cross the delicate crown. In time, that can damage the crown. NOTE: John Krieger of Krieger Barrels also advises his customers not to pull a bronze brush backwards across the crown.
Response to Skeptics
Whenever we’ve published similar advice, given by guys who are producing some of the most accurate barrels in the world, some readers get extremely angry. They say, “You’re crazy! I’ve was pullin’ triggers when you were still in diapers. I’ve got Hall of Fame points and I say there’s no way a phosphor bronze brush can ever do anything to steel. You’re full of it.” Well, these guys are entitled to their opinion. But here’s our response. Number one, we’re just telling you what the barrel-makers are telling US. Don’t kill the messenger. Number two, many of the guys who say bronze brushes can’t affect the crown are the same guys who feel they need to recrown their barrels every 400-500 rounds (Do we see a connection?). Third, if you don’t think a softer material can affect steel, look at the steel ferrules of a well-used fishing rod — there the steel is worn away by plastic. (With time, water will wear away granite.) Lastly, this Editor can tell you I’ve seen the damage myself, first-hand, using a magnifying glass on much-brushed benchrest barrels. Right at the muzzle, the top edge of the lands had sharp, jagged edges that looked like little shark’s teeth, or the edge of a serrated knife. By contrast, a new barrel will have a nice, smooth straight edge along the top of the lands at the muzzle.
Also Be Careful with Jags
Bartlein’s experts also told us to be careful about the jags you use. Dewey-style jags in particular can cause problems. These have a long shaft with multiple rings with diamond-pattern “teeth”. The teeth are designed to grip a patch. The problem is that the lower rings may be exposed below the patch fabric, so the teeth can grind directly on the rifling and/or crown. Bartlein says Dewey-style metal jags can damage a crown very quickly if any of the toothed rings are exposed, metal-on-metal. Tim North of Broughton barrels also advises against using the Dewey-style jags with toothed rings. Interestingly, Dewey uses the same type of diamond-shaped teeth on the bottom of its “Crocogator” primer pocket tool, so you know those knurled teeth can scrape.
Readers often ask “What’s the difference between a Weaver scope rail and a Picatinny Rail?” The answer is not as simple as it seems. The dimensions of a Picatinny Rail should be consistent (from one rail-maker to another), since there IS a government spec. Conversely, there is some variance in “Weaver-style” rails. The width of the groove is the most important difference between Picatinny Rails and Weaver-type rails. “Mil-spec” Picatinny rails will have a grove width of 0.206″ while Weaver rails typically have a narrower, 0.180″ groove width.
Does your rifle have a Weaver Rail or Picatinny Rail? Check the dimensions to be sure.
A while back, Brownells had a helpful GunTech™ Article that discussed the Picatinny Rail vs. Weaver Rail. That article explained:
What are the differences between the ‘Picatinny’ and the ‘Weaver’ systems? The profile of the two systems is virtually identical. Depending on the quality of the machining done by the manufacturer, the two systems should be indistinguishable from the profile. The key difference lies in the placement of the recoil grooves and with width of the grooves. MIL-STD-1913 (Picatinny) grooves are .206″ wide and have a center-to-center width of .394”. The placement of these grooves has to be consistent in order for it to be a true Picatinny MIL-STD system. Weaver systems have a .180” width of recoil groove and are not necessarily consistent in a center-to-center measurement from one groove to the next.
In many instances, a Weaver system has a specific application that it is machined for, so interchangeability is not necessarily an issue. A MIL-STD-1913 system must adhere to the specifications listed above in order for it to be considered MIL-STD, since the military desires uniformity in the recoil grooves to allow for different systems to be mounted on the weapon with no concern for compatibility.
Now, what does this mean? Boiled down, it means that accessories designed for a Weaver system will, in most cases, fit on a Picatinny system. The reverse, however, is probably not the case. Due to the larger recoil groove, Picatinny accessories will not fit a Weaver system. There are, of course, exceptions to every rule, but for a good rule-of-thumb, [full-width] Picatinny won’t fit Weaver, but Weaver accessories WILL fit Picatinny.
For our readers, here’s a selection of FREE printable precision and fun targets. You can download these targets as PDF files and then print them out on 8.5×11″ paper.
AccurateShooter.com offers a cool page with over 50 FREE downloadable targets. You’ll find all types or FREE targets — sight-in targets, varmint targets, rimfire targets, bullseye targets, tactical targets, load development targets and more. CLICK HERE for all our free targets, including our LOAD DEV target.
We created the above target a decade ago. Since then it has been used by tens of thousands of shooters. It has proven very popular as a load development target, since all your load data fits neatly in the boxes under each target. In fact this target is being employed by both rifle-makers and barrel-makers (including Criterion) to test their products. The target was designed for aiming efficiency. The diamonds have 1/2″ sides and you can align your cross-hairs on the horizontal and vertical lines. It is a clean design that is easy to see even at 200 yards with a 20X scope. When we test, we usually crank in a little elevation, setting the point-of-impact higher, so that our shots fall in the gray circles. That way you leave the squares intact for precise aiming.
Versatile Targets with Multiple Aiming Points
We use the two targets below for load development and precision practice. For the left target, use the corners of the diamonds to align your cross-hairs precisely. The circle dot target (on the right) can also be used for informal rimfire competition at 50 yards. Right-Click Each Target to Download Printable PDFs.
Know-Your-Limits Target for Rimfire Training & Fun Matches
Here’s a rimfire training target with “big to small” target circles. Start with the largest circles, then move to the smaller ones in sequence. This systematic drill provides increasing challenge shot-by-shot. Novices often are quite surprised to see their accuracy improve as they move from bigger to smaller aiming points. That provides positive feedback — always a good thing.

Quality Paper Stock Is Important
If you want your self-printed targets to show shots cleanly (and not rip when it gets windy), you should use quality paper stock. We recommend card stock — the kind of thick paper used for business cards. Card stock is available in both 65-lb and 110-lb weights in a variety of colors. We generally print black on white. But you might experiment with bright orange or yellow sheets. Forum Member ShootDots report: “They sell cardstock at Fed-Ex Kinko! I use either Orange or Yellow. That makes it easy to see bullet holes clearly.”
Here are some Target-Printing Tips from our Forum members:
“Staples sells a 67-lb heavy stock that I have settled on. I use the light grey or light blue, either of these are easy on the eyes on bright days. I have used the 110-lb card stock as well and it works fine. It’s just a little easier to print the lighter stuff.” (JBarnwell)
“Cardstock, as mentioned, works great for showing bullet holes as it doesn’t tear or rip like the thin, lightweight 20-lb paper. I’ve never had a problem with cardstock feeding in the printer, just don’t stick too many sheets in there. If I need three targets, I load only three card stock sheets”. (MEMilanuk)
“20-lb bond works pretty well for me if I use a spray adhesive and stick the entire back of the paper’s surface to the backer board.” (Lapua40X)
The U.S. Army Marksmanship Unit (USAMU) has published a great series of reloading “how-to” articles on its Facebook Page. This post covers key factors to consider when loading ammunition for Match Rifles and Service Rifles, with a particular focus on self-loading “gas guns”. Visit the USAMU Facebook Page regularly for other, helpful reloading and marksmanship tips.
We offer some “cardinal rules” to help new gas-gun handloaders with safety and efficiency. These address both Match Rifle and Service Rifle versions of the AR15, M1 Garand, M1A, and M110. However, they can also improve safe reloading for many other auto-loaders such as M1 Carbines, FALs, SIGs, etc. The author distilled these principles many years ago to help focus on the essential aspects of these rifles.
RULE ONE: Service Rifles Are Not Benchrest Rifles
Gas-guns require a relatively loose fit between ammunition and chamber (vs. bolt actions) for safe, smooth operation. Many techniques, such as neck sizing and keeping cartridge headspace quite tight, are popular in the extreme bolt gun accuracy realm. However, they are of little value with Service Rifles, and some could even be hazardous. Before adopting a specialized technique, seriously consider whether it is appropriate and beneficial in a gas-gun.
RULE TWO: Never Compromise Safety to Obtain Accuracy
Example: If choosing a brand of great, but ultra-sensitive match primers offers possibly better accuracy at the risk of slam-fires in your design of rifle, don’t do it! You are issued exactly two eyes and ten fingers (best-case scenario). Risking them trying to squeeze 0.25 MOA better accuracy out of an M1A, etc. simply isn’t worth it.
RULE THREE: Tailor the Precision to Your Individual Skill and Your Rifle’s Potential
This has been addressed here before, but bears repeating for newcomers. If you are struggling to break out of the Marksman Class, or using a CMP M1 “As-Issued,” then laboriously turning the necks of your 600-yard brass is a waste of time. Your scores will improve much faster by practicing or dry-firing. On the other hand, if the reigning champions anxiously check your scores each time you fire an event, a little neck-turning might not be so far-fetched.
Verifying Load Improvements — Accuracy hand-loading involves a wide variety of techniques, ranging from basic to rather precise. Carefully select those which offer a good return on investment for your time and labor. In doubt? Do a classic pilot study. Prepare ammo for at least three or four ten-shot groups with your new technique, vs. the same with your standard ammo. Then, pick a calm day and test the ammo as carefully as possible at its full distance (e.g. 200, 300, or 600 yards) to verify a significant improvement. A little testing can save much labor!
This video explains the procedure for ordering an M1 Garand from the CMP.
RULE FOUR: Be Your Own Efficiency Expert
Serious Service Rifle shooters generally think of ammunition in terms of thousands of rounds, not “boxes”, or even “hundreds”. Analyze, and WRITE DOWN each step in your reloading process. Count the number of times each case is handled. Then, see if any operations can be dropped or changed without reducing safety or accuracy. Eliminating just two operations saves 2000 steps per 1000 rounds loaded. Conversely, carefully consider any measurable benefits before adding a step to your routine.
RULE FIVE: In Searching for Greater Accuracy with Efficiency, Look for System Changes
For example, instead of marking your 300-yard rounds individually to differentiate them from your 200-yard ammo, would a simple change in primers work? If accuracy is maintained, using brass-colored primers for 200 and silver for 300 provides an indelible indicator and eliminates a step! Similarly, rather than spending hours selecting GI surplus brass for weight and neck uniformity, consider splurging on some known, high-quality imported match brass for your 600-yard loads. Results should be excellent, time is saved, and given limited shooting at 600 yards, brass life should be long.
RULE SIX: Check All Your Primers Before Packaging Your Loaded Ammo
This seems simple and even intuitive. However, many slam-fires (which were much more common when M1s and M1As were the standard) are due, at least in part, to “high” primers. Primers should be seated below flush with the case head. The USAMU has addressed this at length in a previous column, but each round should be checked for properly-seated primers before they are packaged for use.
