How to Kill a Barrel in One Afternoon — Firing Rate and Heat

barrel life test rapid fire cooling

Can sustained rapid-fire shooting with no cool-down period wear out a quality barrel more quickly? The answer is “Yes” according to Forum member LCazador, who did an interesting comparison test with two .243 Winchester barrels. He started off with two, identical, match-grade HV taper stainless barrels. Both were NEW at the start of testing, and LCazador shot the same load through each: 95gr match bullets with 38 grains of Hodgdon Varget. After giving both barrels the same, gentle 20-round break-in, 300 rounds were then fired through each barrel — in very different ways. Barrel condition and wear were monitored with a borescope.

Barrel One — Slow Fire, Cool Down Periods, Cleaning Every 50 Rounds
At the end of the 300-round test, Barrel One looked brand new. There was none of the severe fire cracking found in Barrel Two. This barrel was shot no more than 10 times without a cool down and firing was done at a much slower pace. Cleaning for this barrel was done every 50 shots.

Barrel Two — Fast Firing, No Waiting, Cleaning Every 100 Rounds
The second barrel, which received hard use and minimal cleaning, was severely damaged with severe fire cracking at the leade and throat. As a result, the barrel had to be re-chambered. This barrel was shot 100 rounds at time without cleaning and was shot up to 20 times in succession without a cool down.

LESSON LEARNED — Heat Kills Barrel Life
Don’t let your barrel get too hot, and keep it clean. One afternoon can ruin a barrel!

Hawkeye Borescope imageMonitoring Barrel Wear with Borescope
Some folks worry too much about what their borescopes reveal — many barrels do not have to be “squeaky clean” to perform well. In fact some barrels run better after ten or more fouling shots. However, a borescope can be very helpful when your barrel starts losing accuracy for no apparent reason. Forum member FdShuster writes:

“A borescope is a positive way of backing up your suspicions when the rifle starts to throw an occasional (soon followed by more frequent) wild shot. Using the scope is also an excellent way to determine that the cause is barrel wear and not simply a need for a concentrated cleaning session to remove built up copper and more importantly, carbon fouling.

I’ve had a few barrels that gave every indication of being shot out. But I ‘scoped them out and found the cause to be nothing more than requiring a good cleaning. They then returned to their usual performance. There’s no guessing involved when you are able to get ‘up close and personal’ using the scope. The borescope also provides an excellent view of the all-important condition of the crown. My borescope is one of the most valuable investments I’ve ever made.”

Ever Heard of the .244 Remington? Hint — It’s a 6mm Remington

6mm Remington .244 Rem .243 Winchester .308 Cartridge AccurateShooter Chuck Hawks Sierra Bullets

What we now know as the “6mm Remington” was originally called the .244 Remington. The cartridge was renamed because it was not a commercial success initially, being eclipsed by the .243 Winchester. The .244 Remington and the 6mm Remington are identical — only the name was changed. Why was the .244 Remington an “also-ran” to the .243 Win? Sierra Bullets Ballistics Technician Paul Box provides some answers…

Was Anything Wrong With The .244 Remington?

by Ballistic Technician Paul Box for Sierra Bullets Blog

The year was 1955. A time of carhops, drive-in movies, and Buffalo Bob. It was also the year that Winchester introduced the .243 Win and Remington counter-punched with the .244 Remington (now more commonly known as the 6mm Remington). The .243 Win was based off the time-proven .308 Win case while Remington chose the old war horse, the 7×57.

We’ve all read countless times how Winchester chose the 1:10″ twist, while Remington adopted the 1:12″ twist for their .244 Rem rifles. The first complaint in the gun magazines of that era was how the faster twist Winchester could handle 100 grain bullets, while Remington’s [12-twist factory rifles were supposedly limited to 90 grain bullets].

The first complaint I remember reading was that the 100-grainer was better suited for deer-sized game and the 1:12″-twist wouldn’t stabilize bullets in this weight range. Now, let’s look at this a little closer. Anybody that thinks a 100-grainer is a deer bullet and a 95-grainer isn’t, has been drinking too much Kool-aid. In all honesty, it’s all about bullet construction and Remington had constructed the [90s] with light game in mind. In other words, Remington got it right, but due to a lack of knowledge at the time on both bullet construction and stability, the .244 never gained the popularity it deserved. At that time, Sierra had the 100gr SMP and Hornady offered a 100gr RN that would both stabilize in the slower 1-12″ twist. The .244 Remington provides another classic example of how the popularity of a cartridge suffered due to a lack of knowledge.

.244 Rem vs. .243 Win — What the Experts Say
Respected gun writer Chuck Hawks says the .244 Remington deserved greater acceptance: “The superb 6mm Remington started life in 1955, the same year as the .243 Winchester. It was originally named the .244 Remington. Although the 6mm lost the popularity contest to the .243, it is one of my favorite rifle cartridges, and much appreciated by reloaders generally. The .244 Rem and 6mm Rem cartridges are completely interchangeable, and anyone with a .244 Rem rifle can shoot [6mm Rem] ammunition in complete safety (or vice-versa). Remington .244 rifles made from 1958 on can stabilize all 6mm bullets, while those made in 1955 through 1957 are limited to loads using spitzer bullets not heavier than 90 grains for best accuracy.”

Nathan Foster, author of The Practical Guide to Long Range Hunting Cartridges, states: “In 1963 Remington attempted to regain ground by releasing .244 rifles with a new 1:9″ twist to handle heavier bullets. The cartridge was renamed the 6mm Remington and new ammunition was loaded giving the hunter the choice of either an 80gr bullet for varmints or a 100gr bullet for deer. In comparison to the .243 Win, factory loads for the .244/6mm Remington are slightly more powerful while hand loads increase this margin further.”

Was the .244 Remington Actually Better than the .243 Winchester?
The .244 Remington (aka “6mm Remington”) has a velocity advantage over the .243 Winchester due to a slightly larger case capacity. The longer case neck of the .244 Remington is considered desirable by handloaders. We like the added capacity and long neck of the original .244 Remington. As renamed the “6mm Remington”, the cartridge HAS developed a following, particularly with varmint hunters looking for a high-velocity 6mm option. But it never achieved the success of the .243 Winchester for many reasons. As a member of the .308 family of cartridges, the .243 Winchester has certain obvious advantages. First, you can simply neck down .308 Win brass, which was available at low cost from many sources. Moreover, a .308 Win or 7mm-08 full-length sizing die could be used for body sizing. Still the .244 Remington (6mm Remington) presents an interesting “what if?” story…

Sunday GunDay: CMP Cup-Winning Rem-Action Eliseo Tubegun

Photography by Meghan Hendricks.

This story is about a great shooter, Joe Hendricks Jr., and his Eliseo RTS Tubegun, chambered in 6mm Competition Match. With this versatile rifle, Joe Hendricks Jr. won the 2019 CMP Cup Aggregate Title for Match Rifles. Joe comes from a long line of talented marksmen. His father AND his grandfather are elite competitive shooters. His dad has been a National Champion, and all three generations have shot together, shoulder to shoulder, on the Remington Rifle Team. Like grandfather, like father, like son.

 alt=

Joe says: “I think it’s pretty cool that there have now been two major Across the Course Championships won by a Hendricks using a Gary Eliseo chassis, one by me this year, and one in 2014 when my father (Joe Hendricks Sr.) won the NRA National Championship.”

Joe Hendricks Jr.’s Rifle — Eliseo RTS Chassis, Rem 40X Action, Krieger Barrel
Joe’s rifle is built on a Competition Machine RTS Target Model chassis. This Tubegun features a Remington 40X action with Pacific Tool & Gauge Bolt and Jewell trigger. The scope is a Leupold 6-18x40mm. The barrel is a Krieger chambered in 6mm Competition Match. Joe explains: “The 6mm Competition Match is a cartridge that my dad came up with. It is basically a .243 Winchester with a 31° shoulder.”

If you look carefully in the photo below, you’ll note the silver-toned, adjustable butt-plate. That’s an upgrade Joe added: “I did a small modification to the stock, where I put on an Anschutz buttplate instead of the standard one Gary Eliseo uses. This Anschutz hardware provides a little bit more adjustability.”

 alt=
Here Joe Hendricks Jr. fires at 200 yards from the standing position.

The Standing Position — Why It’s Critical to Match Success
Joe told us: “As far as shooting strategies and training methods go, I shoot a lot of standing practice — at least 50 shots per session. I still train the other positions of course, but I believe if you start your day off with a great standing score, it really makes the rest of the day easy because then you don’t feel like you’re playing catch-up the whole time.”

Joe explains: “When I’m shooting standing, I shoot in a manner very similar to the way that Carl Bernosky does. He’s written a few articles about the standing position. He always talks about making sure the shot goes off inside his hold, and I’m the same way. I don’t try to do too much. I just let the gun do its thing and when/if it stops in the Ten Ring, I shoot the shot. If it doesn’t, I don’t.”

About the CMP Cup Two-Day Course of Fire
The CMP Cup is a two-day match comprised of two, 1000-point Aggregates, for a 2000-point Grand Agg. Each day, the competitors fire 100 shots total from the 200, 300, and 600 yard lines. The match starts with 20 shots slow fire standing at 200 yards. Next are two, 10-shot, rapid fire strings in 60 seconds from the sitting position. Next are two, 10-shot strings in 70 seconds prone at 300 yards (rapid fire prone). Each day’s course of fire concludes with two, 20-shot sequences of slow-fire prone at 600 yards.

Joe Hendricks Jr. CMP Cup Eliseo tubegun RTS 6 Competition High Power

6mm Competition Match Cartridge — Slower Powder Yields Better Barrel Life
My dad was shooting a 6XC for a while and was getting tired of going through almost two barrels a year. So, he came up with the 6mm Competition Match. Like I said, it is a .243 Winchester with a 31-degree shoulder. This delivers the same (if not better) velocity as the other popular 6mm cartridges, but we get almost double the barrel life because we increased the case capacity, so we can shoot a slower burning powder. The barrel I took to Camp Perry that won the CMP Cup had over 3700 rounds on it when I was finished. [EDITOR: Take note readers! Most 6mm barrels are toast after 2500 rounds.] Granted it definitely needed to come off at that point, but it obviously was still shooting well enough to win!

Accurate Load with Peterson Brass, Berger Bullets, and Vihtavuori N165
The two loads I shot all week were Berger 108gr BT behind Vihtavuori N165 in Peterson Cartridge Company brass for 200 and 300 yards, and then Berger 115 VLD behind N165 in Peterson brass for 600 yards. Both loads are easily going over 3000 FPS. I try to only use the best components for reloading, so that’s why I go with Berger, Vihtavuori, and Peterson. Obviously Berger and Vihtavuori quality are pretty known, but I believe Peterson is right up there with Lapua[.] I’ve visited the Petersen factory many times. I’m always blown away by the time and effort Peterson puts into everything.

Winning Marksmanship — the Mental Game
The other big thing I’ve been focusing on lately is my mental game. In order to be at the top of a sport, regardless of the sport, the athlete has to have a solid mental approach. For me, I’ve learned that my key is confidence. A good shooting buddy, who was with me the first day of the CMP Cup, suggested I was arrogant because I kept telling him I was going to win. Then I told him it was confidence not arrogance. If I was confident in my ability, I did not think there was any way I could lose. [Editor: To help build confidence and visualize success, we recommend With Winning in Mind, by Lanny Bassham, an Olympic gold-medal winning marksman.]

All in the Family — Three Generations of Hendricks Marksmen

Joe’s father, Joseph Hendricks Sr., has been a National Champion rifle shooter. Joe’s grandfather, Gary Hendricks, is also a talented marksman. In fact, all three men — grandfather, father, and son — shot together on the Remington Rifle Team. Joe says that the shooting sports have helped build strong family bonds. He and his father enjoy shooting together, and competing against one another: “I learn so much just by watching my dad… shoot. Even though I have been competing for 10 years now, I’m still incredibly new to the shooting sports compared to my dad. My father is always there to help.”

“I feel very privileged to have grown up in the family that I did, with not only my father as a competitive shooter, but my grandfather as well. I definitely would not be the person I am today, let alone the shooter, without either of them. At one point, all three of us were on the Remington Rifle Team. I’ve had the opportunity to shoot team matches with all three of us on one team, as recently as this past summer.”

“Initially when I began shooting competitively, I was putting a lot of pressure on myself. I wanted to be as good a shooter as my dad and grandfather. I was trying so hard that it was really affecting my scores negatively. Then one year, I told myself I was just going to have fun, and not worry about match scores. That year was the year I really started to win things, and shoot some good scores.”

 alt=

“When my father won the NRA National Championship in 2014, I was so proud, but along with being proud, all it did was make me more motivated. Ever since I started shooting, I wanted to win a National Championship, but after he won, it just fueled my fire more. There is a bit of father/son rivalry. It’s a lot of fun if we are shooting right next to each other at the same time. We just give each other crap about shooting a bad a shot, or shooting a lower score by a point or an X.”

“My dad started shooting when he was around 10, so he has a vast amount of knowledge compared to most people, especially me. He is always there to help whenever I have a question on anything firearm or shooting related. To this day, whenever I’m done with a match, I always talk to my dad. He always has time to listen to what I have to say.”

The .244 Remington — Why and How It Failed to Succeed

Sunday GunDay: Matt’s Screamin’ Yellow .243 Ackley Improved

.243 Win Ackley Improved ST1000 stock varmint rifle 1000-yard benchrest

.243 Ackley Improved for Long-Range Varminting and Benchrest Competition
Whenever Matt Bianchini brings his bright yellow .243 Ackley to the firing line, heads turn. This is one truly handsome rig–as good-looking as it is accurate. Built to smoke varmints at long-range as well as compete in 1000-yard benchrest matches, this rifle is proof that competition improves the breed. Fitted with a Farley action, Jewell trigger, Leupold LRT scope, and Lilja or Krieger barrel, the Yellow Ackley is a “no compromise” match rifle that can run with the big dogs in 1K Benchrest competition. And with the Ackley’s ability to toss 106gr Clinch Rivers at 3350 fps, this is one flat-shooting, hard-hitting varmint rifle.

.243 Win Ackley Improved ST1000 stock varmint rifle 1000-yard benchrest

Ultra-Fast, Ultra-Smooth Farley Action…and One Wicked Paint Job
The heart of Matt’s rifle is a Farley action. Farleys have found favor with Benchrest competitors, because the bolt can be worked so fast. And the Farley is as smooth as it is speedy. The difference is quite noticeable if you compare it to a blue-printed Rem 700, or even a recent Stolle Panda. Farleys were true customs, built one at a time by the Farley family in Oklahoma. Unlike a BAT action which is machined from billet steel, a Farley starts with a stainless investment casting, much like Ruger pistol frames. It uses a cone bolt for smooth, yet solid lock-up.

One of the unique features of the Farley is the ejector–it can be switched on or off, depending on the shooter’s preference. So, if you’re load testing some hot rounds, you can turn the ejector off. In a match you can turn the ejector “on” to function normally. Matt is now a confirmed Farley fanatic. He tells us: “I’ve got quite a few other very nice actions, including Nesikas. But none of them are as slick as that Farley. When you work the bolt it feels like it’s on ball-bearings.”

Matt’s Screamin’ Yellow Ackley–The Need for Speed

.243 Win Ackley Improved ST1000 stock varmint rifle 1000-yard benchrest

.243 Ackley Improved Speed Demon
In a long-range varmint rifle, speed kills. Ultra-high velocities will deliver flatter trajectories and more explosive hits on critters. That’s where the .243 Ackley Improved really shines.

.243 Win Ackley Improved ST1000 stock varmint rifle 1000-yard benchrest

Matt has explored the upper limits of .243 Ackley Improved (AI) performance with his yellow long-range rig, fitted with a 29″ Lilja 3-groove, 1:8″-twist barrel. Using a stout load of Alliant Reloder 25, Matt’s “Screamin’ Yellow Ackley” has topped 3340 fps with Clinch River 106s. That’s serious speed for heavy 6mm bullets. This shows a well-built .243 AI leaves Dashers and 6XCs in the dust when it comes to pure velocity.

.243 Win Ackley Improved ST1000 stock varmint rifle 1000-yard benchrestUltimate Evolution of the .243 Winchester
Matt’s show-stopping rifle is a .243 Ackley Improved (40-degree shoulder, .271″ neck), chambered with a Manson reamer. On top of the stainless Farley “S” action, in Farley 30mm rings, sits a Leupold LRT (1/16 MOA dot) boosted to 18X-40X by Premier Reticles. Matt has SIX barrels for the gun, three Lilja 3-grooves, a couple Kriegers, and a Shilen.

Matt’s gun currently sports an 8-twist 29″ Lilja 3-groove HV taper that Matt says cleans up like a dream. The stock is a Shehane ST-1000 Tracker made in fiberglass by McMillan, with a BAT trigger guard and Shehane polished billet aluminum buttplate. Prior to final finishing, Matt worked over the flats and some of the angles. That’s why the facets are so well-defined on this rifle compared to some ‘glass Trackers you may have seen. The gun was chambered by Dave Bruno of Cheswick, PA.

Matt bedded the stock and applied the stunning Sikken “Viper” yellow paint job himself. That flawless, smooth-as-glass Screamin’ Yellow finish is no ordinary paint-job, but then Matt Bianchini is no ordinary do-it-yourself painter. His family runs an automotive body-shop, so he had access to premium paints and a quarter-million-dollar spray booth with all the latest technology. Still, Matt spent many hours on this stock to get everything right, trying a couple colors before he settled on a Sikken automotive “Viper Race Yellow” formulated for the Dodge Viper sports car. After careful prep work, Matt sprayed two coats of Viper Yellow, and then added three coats of high-grade automotive clear, which was then baked-on in a heat chamber. Matt also painted the Sinclair front rest to match the stock, and even polished the surfaces of the Hoehn windage top. A lot of effort, Matt told us, was required to achieve the results you see here.

3300 fps for 1000 Yards
Though Matt’s Ackley has harvested its share of varmints, the gun was built with 1000-yard benchrest competition in mind. At left is the firing line at Thunder Valley, Ohio. Yep those targets (upper right) are 1000 yards away. Now you know why Matt has a 40-power scope.

.243 Win Ackley Improved AI varmint rifle

.243 Win Ackley Improved AI varmint rifle

The Yellow Ackley weighs just under 17 pounds to meet IBS and NBRSA “Light Gun” weight limits. While Matt says his bullets don’t “go to sleep” for a couple hundred yards, this gun can still shoot 1/4″ groups at 100 yards and hold that accuracy much, much farther. Matt reports, “my best-ever group was five shots in .397″ at 400 yards. Yep, I got lucky with the conditions, but this is a very accurate rifle.”

.243 Ackley Improved–More Velocity, Less Case Stretch

by Bob Blaine, Sinclair International

Parker Ackley reluctantly developed the .243 Ackley Improved (“AI”). Ackley finally gave in to his customers’ requests to develop the .243 AI. He had always felt that the .243 Winchester was already an improved configuration, but he did say that the best thing to be gained by improving the .243 Winchester was to substantially reduce the case-stretching problems. The .243 Winchester parent case has always stretched brass, almost as bad as the Swift. Even though you get more velocity with the improved .243, I’ve also found that the improved version gives a bit more throat life than the parent case does.

The .243 AI delivers more velocity by virtue of enhanced case capacity–roughly five grains more H20 capacity than a standard .243 Winchester. The .243 AI has a water capacity of approximately 57 to 58 grains, compared to 52-53 grains for the standard .243 Winchester.

Loading for Long-Range
For long-range shooting, Matt loads 106gr Clinch Rivers with 47.5gr of Alliant Reloder 25 for his Krieger barrels, a little more powder with the Lilja 3-grooves. The Lilja load runs 3342 fps, with a 3.228″ OAL. Cases are neck-turned Lapua .243 Winchester. He uses Wilson inline seater and Wilson eck-sizer dies (.267″ bushing), and a custom, reamer-cut FL sizing die.

Not Just for BR, This Gun Can Hunt
While Matt has a big stable of varmint rifles, the Yellow Ackley has seen plenty of duty in the ‘Hog fields. Matt is from a farming family and he can shoot practically right out his back door (see top photo at the farm). He has nailed some big ground-hogs at 800 yards and beyond. The .243 AI does kick a bit compared to other varmint cartridges, but even with 105-106gr bullets, it’s not bad. He has considered adding a muzzle brake at some point to one of the barrels, just so he can see impacts better.

Screamin’ Yellow Dasher?

Matt originally thought of building the gun up as a 6BR or a 6BR Improved. He has a Manson reamer similar to a 6mm Dasher, with a 40-degree shoulder and .008″ body taper. He actually chambered a couple barrels with that 6BR Improved reamer, but he hasn’t shot them yet. He was so pleased with how the gun performed in .243 AI, that he saw no reason to change. And it may be a while before he slaps a Dasher-chambered barrel on the rig: “I really like the way it shoots as a .243 AI. I’m so impressed with it that I don’t want to mess with anything. And I don’t think I’ll be running out of Ackley barrels anytime soon.”

.243 Win Dies and Reloading Gear

Since the .243 Win is such a popular cartridge, all the major die-makers offer reloading dies. It’s hard to go wrong with a Redding Type ‘S’ Full-length bushing die–item 77114 for the standard .243 Win and item 77420 for .243 AI. Whidden Gunworks also makes great .243 Win sizing dies (and custom .243 Win AI dies on request). These will both resize the case (and bump the shoulder) as necessary, and allow you to adjust neck tension with bushings. Alternatively, you can go with a body die, and a separate neck bushing die.

If you load primarily one brand of bullets, another slick set-up is to buy a Forster or Whidden full-length, non-bushing .243 Win sizing die, and then have Forster or Whidden hone the neck for your desired amount of tension. This elegant one-pass sizing solution produces very straight rounds with low run-out.

For bullet seating, both the Redding Competition Seater (item 55114) and the Forster Ultra-Seater (item U00034) work great for the standard .243 Win case. If you shoot a .243 Ackley, Redding’s .243 AI Comp Seater (item 55420) costs quite a bit more than the standard version Forster doesn’t list a .243 AI seater in their catalog. However, you can just run your chambering reamer into the inner sleeve of either seating die to fit the .243 Ackley Improved case.

If you want the “Cadillac” of production seater dies for the .243 Win, order the Wilson Stainless Micrometer seater (item 50-1114S) from Sinclair International. Costing only a few dollars more than a Redding Comp seater, this die is a joy to use, providing very positive control over bullet seating depth. When used with a quality arbor press, the Wilson offers unrivaled “feel” for bullet-seating force. This can help you monitor neck tension, one of the most critical factors in maintaining low ES and SD for long-range accuracy.

Sunday GunDay: Joe Hendricks Jr.’s CMP Cup-Winning Tubegun

Photography by Meghan Hendricks.

This story is about a great shooter, Joe Hendricks Jr., and his Eliseo RTS Tubegun, chambered in 6mm Competition Match. With this versatile rifle, Joe Hendricks Jr. won the 2019 CMP Cup Aggregate Title for Match Rifles. Joe comes from a long line of talented marksmen. His father AND his grandfather are elite competitive shooters. His dad has been a National Champion, and all three generations have shot together, shoulder to shoulder, on the Remington Rifle Team. Like grandfather, like father, like son.

Joe says: “I think it’s pretty cool that there have now been two major Across the Course Championships won by a Hendricks using a Gary Eliseo chassis, one by me this year, and one in 2014 when my father (Joe Hendricks Sr.) won the NRA National Championship.”

Joe Hendricks Jr.’s Rifle — Eliseo RTS Chassis, Rem 40X Action, Krieger Barrel
Joe’s rifle is built on a Competition Machine RTS Target Model chassis. This Tubegun features a Remington 40X action with Pacific Tool & Gauge Bolt and Jewell trigger. The scope is a Leupold 6-18x40mm. The barrel is a Krieger chambered in 6mm Competition Match. Joe explains: “The 6mm Competition Match is a cartridge that my dad came up with. It is basically a .243 Winchester with a 31° shoulder.”

If you look carefully in the photo below, you’ll note the silver-toned, adjustable butt-plate. That’s an upgrade Joe added: “I did a small modification to the stock, where I put on an Anschutz buttplate instead of the standard one Gary Eliseo uses. This Anschutz hardware provides a little bit more adjustability.”

 alt=
Here Joe Hendricks Jr. fires at 200 yards from the standing position.

The Standing Position — Why It’s Critical to Match Success
Joe told us: “As far as shooting strategies and training methods go, I shoot a lot of standing practice — at least 50 shots per session. I still train the other positions of course, but I believe if you start your day off with a great standing score, it really makes the rest of the day easy because then you don’t feel like you’re playing catch-up the whole time.”

Joe explains: “When I’m shooting standing, I shoot in a manner very similar to the way that Carl Bernosky does. He’s written a few articles about the standing position. He always talks about making sure the shot goes off inside his hold, and I’m the same way. I don’t try to do too much. I just let the gun do its thing and when/if it stops in the Ten Ring, I shoot the shot. If it doesn’t, I don’t.”

About the CMP Cup Two-Day Course of Fire
The CMP Cup is a two-day match comprised of two, 1000-point Aggregates, for a 2000-point Grand Agg. Each day, the competitors fire 100 shots total from the 200, 300, and 600 yard lines. The match starts with 20 shots slow fire standing at 200 yards. Next are two, 10-shot, rapid fire strings in 60 seconds from the sitting position. Next are two, 10-shot strings in 70 seconds prone at 300 yards (rapid fire prone). Each day’s course of fire concludes with two, 20-shot sequences of slow-fire prone at 600 yards.

6mm Competition Match Cartridge — Slower Powder Yields Better Barrel Life
My dad was shooting a 6XC for a while and was getting tired of going through almost two barrels a year. So, he came up with the 6mm Competition Match. Like I said, it is a .243 Winchester with a 31-degree shoulder. This delivers the same (if not better) velocity as the other popular 6mm cartridges, but we get almost double the barrel life because we increased the case capacity, so we can shoot a slower burning powder. The barrel I took to Camp Perry that won the CMP Cup had over 3700 rounds on it when I was finished. [EDITOR: Take note readers! Most 6mm barrels are toast after 2500 rounds.] Granted it definitely needed to come off at that point, but it obviously was still shooting well enough to win!

Accurate Load with Peterson Brass, Berger Bullets, and Vihtavuori N165
The two loads I shot all week were Berger 108gr BT behind Vihtavuori N165 in Peterson Cartridge Company brass for 200 and 300 yards, and then Berger 115 VLD behind N165 in Peterson brass for 600 yards. Both loads are easily going over 3000 FPS. I try to only use the best components for reloading, so that’s why I go with Berger, Vihtavuori, and Peterson. Obviously Berger and Vihtavuori quality are pretty known, but I believe Peterson is right up there with Lapua[.] I’ve visited the Petersen factory many times. I’m always blown away by the time and effort Peterson puts into everything.

Winning Marksmanship — the Mental Game
The other big thing I’ve been focusing on lately is my mental game. In order to be at the top of a sport, regardless of the sport, the athlete has to have a solid mental approach. For me, I’ve learned that my key is confidence. A good shooting buddy, who was with me the first day of the CMP Cup, suggested I was arrogant because I kept telling him I was going to win. Then I told him it was confidence not arrogance. If I was confident in my ability, I did not think there was any way I could lose. [Editor: To help build confidence and visualize success, we recommend With Winning in Mind, by Lanny Bassham, an Olympic gold-medal winning marksman.]

All in the Family — Three Generations of Hendricks Marksmen

Joe’s father, Joseph Hendricks Sr., has been a National Champion rifle shooter. Joe’s grandfather, Gary Hendricks, is also a talented marksman. In fact, all three men — grandfather, father, and son — shot together on the Remington Rifle Team. Joe says that the shooting sports have helped build strong family bonds. He and his father enjoy shooting together, and competing against one another: “I learn so much just by watching my dad… shoot. Even though I have been competing for 10 years now, I’m still incredibly new to the shooting sports compared to my dad. My father is always there to help.”

“I feel very privileged to have grown up in the family that I did, with not only my father as a competitive shooter, but my grandfather as well. I definitely would not be the person I am today, let alone the shooter, without either of them. At one point, all three of us were on the Remington Rifle Team. I’ve had the opportunity to shoot team matches with all three of us on one team, as recently as this past summer.”

“Initially when I began shooting competitively, I was putting a lot of pressure on myself. I wanted to be as good a shooter as my dad and grandfather. I was trying so hard that it was really affecting my scores negatively. Then one year, I told myself I was just going to have fun, and not worry about match scores. That year was the year I really started to win things, and shoot some good scores.”

 alt=

“When my father won the NRA National Championship in 2014, I was so proud, but along with being proud, all it did was make me more motivated. Ever since I started shooting, I wanted to win a National Championship, but after he won, it just fueled my fire more. There is a bit of father/son rivalry. It’s a lot of fun if we are shooting right next to each other at the same time. We just give each other crap about shooting a bad a shot, or shooting a lower score by a point or an X.”

“My dad started shooting when he was around 10, so he has a vast amount of knowledge compared to most people, especially me. He is always there to help whenever I have a question on anything firearm or shooting related. To this day, whenever I’m done with a match, I always talk to my dad. He always has time to listen to what I have to say.”

Sunday GunDay: 1000-Yard Prone Rifle — Corbin’s “Maple Marvel”

.243 Win 1000 yard Maple rifle

“I have molested that rifle on several different occasions over the years. It is more beautiful in person if that is possible. Fine craftsmanship in every aspect.” — Forum Member Matt K.

.243 Win prone rifle Corbin ShellToday’s Sunday GunDay feature is a “blast from the past”, part of our big Guns of the Week archive. Some years back, Forum member Corbin Shell told us he had a new, full-custom 1000-yard prone rifle. When he sent some photos of the maple-stocked masterpiece, our collective jaws dropped. Check it out — this is truly a “Maple Marvel”.

.243 Win 1000 yard Maple rifle

Corbin’s GunDay rig is an eye-catcher for sure. This is one handsome rifle, built with all-premium components and a stunning Curly Maple thumbhole stock with adjustable cheekpiece. The rifle is chambered in .243 Winchester. It features a custom stainless RBRP action Nesika R action, with keycuts in the bottom instead of recoil lug. A Grünig & Elmiger trigger has been specially modified (milled and pinned) to work with the Nesika action. The primary barrel is a 30″ Broughton 5R Palma-contour tube. Interestingly, Corbin has a second 30″ Broughton barrel chambered in 6mmBR for use at shorter ranges.

The trigger guard, fore-arm rail, cheek adjuster, and 4-way adjustable butt assembly are all custom metal, designed by Dan Gleason. The stock is cut from exhibition-grade fiddleback maple (from Cecil Fredi Gunstocks in Las Vegas) with a Gaboon Ebony tip wood and butt-plate spacer.

Fast and Accurate
Corbin tells us the gun will put five shots into the size of a quarter at 300 yards “when he does his part.” Corbin shoots pointed Berger 105gr VLDs and 45.5 grains of H4831SC. That load runs 3180 fps. He can push it faster, but “that’s where the node was and where it shoots best”, according to Corbin.

Forum member Jim Hardy has seen (and shot against) this beautiful rifle. Jim reports: “A casual observer might think that the trigger guard, cheek plate and butt plate hardware are Anschutz — as the stock takes on the Anschutz prone pattern. However, this is ALL custom metal. The G&E trigger breaks like a glass rod and will makes my BR triggers feel inferior at best. I had the pleasure of holding, shouldering, and lusting over this gun at Camp Perry last year, and it is even more impressive in person. The killer is that there is yet ANOTHER one in a beautiful, dark figured walnut owned by Corbin’s shooting partner. BTW, both guns will hammer at 1000 yards prone.”

Long Range Prone Shooting with the .243 Winchester
Is the .243 Winchester capable at 1000 yards? Absolutely. John Whidden has used the .243 Win to capture multiple NRA National Long-Range Championships. John selected the .243 Win because it offers excellent ballistics with manageable recoil. John says that, at least for a sling shooter, the .243 Win is hard to beat at long range. John explains that, while you CAN get somewhat better ballistics with a .284 Win or .300 WSM, you’ll pay a heavy price in increased recoil with those bigger cartridges.

Running at an impressive 3275 FPS from his .243 Win, Berger 6mm 105 grain Hybrids are hard to beat, according to Whidden: “My .243 Win shoots inside a 6.5-284 with 142-grainers. Nothing out there is really ahead of [the .243], in 1000-yard ballistics unless you get into the short magnums or .284s and those carry a very significant recoil penalty.” John has tried bigger cases: “In the past I did shoot the 6.5-284. I went to the .243 Win because it had similar ballistics but had much less recoil. It doesn’t beat me up as much and is not as fatiguing.” READ Whidden .243 Winchester Report.

Cartridge History: Ever Heard of the .244 Remington?

6mm Remington .244 Rem .243 Winchester .308 Cartridge AccurateShooter Chuck Hawks Sierra Bullets

What we now know as the “6mm Remington” was originally called the .244 Remington. The cartridge was renamed because it was not a commercial success initially, being eclipsed by the .243 Winchester. The .244 Remington and the 6mm Remington are identical — only the name was changed. Why was the .244 Remington an “also-ran” to the .243 Win? Sierra Bullets Ballistics Technician Paul Box provides some answers…

Was Anything Wrong With The .244 Remington?

by Ballistic Technician Paul Box for Sierra Bullets Blog

The year was 1955. A time of carhops, drive-in movies, and Buffalo Bob. It was also the year that Winchester introduced the .243 Win and Remington counter-punched with the .244 Remington (now more commonly known as the 6mm Remington). The .243 Win was based off the time-proven .308 Win case while Remington chose the old war horse, the 7×57.

We’ve all read countless times how Winchester chose the 1:10″ twist, while Remington adopted the 1:12″ twist for their .244 Rem rifles. The first complaint in the gun magazines of that era was how the faster twist Winchester could handle 100 grain bullets, while Remington’s [12-twist factory rifles were supposedly limited to 90 grain bullets].

The first complaint I remember reading was that the 100-grainer was better suited for deer-sized game and the 1:12″-twist wouldn’t stabilize bullets in this weight range. Now, let’s look at this a little closer. Anybody that thinks a 100-grainer is a deer bullet and a 95-grainer isn’t, has been drinking too much Kool-aid. In all honesty, it’s all about bullet construction and Remington had constructed the [90s] with light game in mind. In other words, Remington got it right, but due to a lack of knowledge at the time on both bullet construction and stability, the .244 never gained the popularity it deserved. At that time, Sierra had the 100gr SMP and Hornady offered a 100gr RN that would both stabilize in the slower 1-12″ twist. The .244 Remington provides another classic example of how the popularity of a cartridge suffered due to a lack of knowledge.

.244 Rem vs. .243 Win — What the Experts Say
Respected gun writer Chuck Hawks says the .244 Remington deserved greater acceptance: “The superb 6mm Remington started life in 1955, the same year as the .243 Winchester. It was originally named the .244 Remington. Although the 6mm lost the popularity contest to the .243, it is one of my favorite rifle cartridges, and much appreciated by reloaders generally. The .244 Rem and 6mm Rem cartridges are completely interchangable, and anyone with a .244 Rem rifle can shoot [6mm Rem] ammunition in complete safety (or vice-versa). Remington .244 rifles made from 1958 on can stabilize all 6mm bullets, while those made in 1955 through 1957 are limited to loads using spitzer bullets not heavier than 90 grains for best accuracy.”

Nathan Foster, author of The Practical Guide to Long Range Hunting Cartridges, states: “In 1963 Remington attempted to regain ground by releasing .244 rifles with a new 1:9″ twist to handle heavier bullets. The cartridge was renamed the 6mm Remington and new ammunition was loaded giving the hunter the choice of either an 80gr bullet for varmints or a 100gr bullet for deer. In comparison to the .243 Win, factory loads for the .244/6mm Remington are slightly more powerful while hand loads increase this margin further.”

Was the .244 Remington Actually Better than the .243 Winchester?
The .244 Remington (aka “6mm Remington”) has a velocity advantage over the .243 Winchester due to a slightly larger case capacity. The longer case neck of the .244 Remington is considered desirable by handloaders. We like the added capacity and long neck of the original .244 Remington. As renamed the “6mm Remington”, the cartridge HAS developed a following, particularly with varmint hunters looking for a high-velocity 6mm option. But it never achieved the success of the .243 Winchester for many reasons. As a member of the .308 family of cartridges, the .243 Winchester has certain obvious advantages. First, you can simply neck down .308 Win brass, which was available at low cost from many sources. Moreover, a .308 Win or 7mm-08 full-length sizing die could be used for body sizing. Still the .244 Remington (6mm Remington) presents an interesting “what if?” story…

.243 Winchester — The Forgotten Long-Range Cartridge

John Whidden gunworks long range championship nra indiana camp perry 2016 2017 atterbury

John Whidden of Whidden Gunworks used the .243 Winchester cartridge to win the 2017 NRA Long Range Championship, his fifth LR title at Camp Perry (and second in a row). John selected the .243 Win because it offers excellent ballistics with manageable recoil. John says that, at least for a sling shooter, the .243 Win is hard to beat at long range. Yes, John says, you can get somewhat better ballistics with a .284 Win or .300 WSM, but you’ll pay a heavy price in increased recoil. Here’s John’s story of how he wins with a .243 Win.

Great Ballistics with 6mm 105s at 3275 FPS
Running at an impressive 3275 FPS, Berger 6mm 105 grain Hybrids deliver ballistics that are hard to beat, according to John Whidden:

“My .243 Win shoots inside a 6.5-284 with 142-grainers. Nothing out there is really ahead of [the .243], in 1000-yard ballistics unless you get into the short magnums or .284s and those carry a very significant recoil penalty. In the past I did shoot the 6.5-284. I went to the .243 Win because it had similar ballistics but had much less recoil. It doesn’t beat me up as much and is not as fatiguing.

John Whidden .243 Winchester Win National Championship Long Range Reloading Caliber Barnard Action Anshutz

With the .243 Win, there’s no tensing-up, no anticipating. With the reduced recoil (compared to a 7mm or big .308), I can break and shoot very good quality shots. I find I just shoot better shots with the .243 than I ever did with the 6.5-284.”

The .243 Winchester — Good Enough to Win LR Championships

by John Whidden, Five-Time National Long Range Champion
My experience with the .243 cartridge for use as a Long Range High Power cartridge dates back about 10 years or so. After building a .300 WSM, I realized that the recoil was hurting the quality of my shots. The WSM shot great, but I couldn’t always execute good shots when shooting it. From here I built a 6.5-284, and it shot well. I also had a very accurate 6mmBR at the time, and my logic in going to the .243 Win was to get wind performance equal to the 6.5-284 with recoil similar to the 6mmBR. The experiment has worked out well indeed!

Championship-Winning Load: Berger Bullets, Lapua Brass, and Vihtavuori N160
For a load, currently I’m shooting Lapua brass, PMC primers (Russian, similar to Wolf), VihtaVuori N160 single-base powder, and Berger 105 grain Hybrid bullets. I switched to the Hybrid bullets fairly recently at the beginning of the 2015 season. Previously I shot the 105gr Berger hunting VLDs, and in testing I found that the Hybrids were just as accurate without having to seat the bullet into the lands. The velocity of this combination when shot through the excellent Bartlein 5R barrels (32” length) is around 3275 FPS. Surprising to some, John does load his ammo on a Dillon Progressive press (with help from his ultra-precise Auto-trickler).

For my match ammo, I seat the Berger 105 Hybrids well off the lands — my bullets are “jumping” from .035″-.060″. I only use one seating depth for ammunition for multiple guns (I know some benchrest shooters will stop reading right here!) and the bullets jump further in the worn barrels than in the fresh barrels. The bullets are pointed up in our Bullet Pointing Die System and are moly-coated. The moly (molybdenum disulfide) does extend the cleaning interval a little bit, probably 20% or so. The Lapua .243 Win brass is all neck-turned to .0125″ thickness.

Whidden’s .243 Win Ammo is Loaded on a Dillon
My loading process is different than many people expect. I load my ammo on a Dillon 650 progressive press using our own Whidden Gunworks dies. However powder charges are individually weighed with a stand-alone automated scale/trickler system from AutoTrickler.com (see below). Employing a high-end force restoration scale, this micro-processor controlled system offers single-kernel precision. The weighed charges are then dropped into the cases with a funnel mounted to the Dillon head.

The Lapua .243 Win brass is full-length sized every time, and I run one of our custom-sized expanders in my sizer die. The expander measures .243″ which yields the desired .001″ neck tension. In my experience, the best way to get consistent neck tension is to run an expander in the case neck at some point. When sizing the case neck by a minimal amount such as is the case here, I don’t find any negative points in using an expander in the sizer die.

In my experience, the keys to accurate long range ammo are top quality bullets and the most consistent neck tension you can produce. From these starting points, the use of quality components and accurate powder measurement will finish out the magic.
