A couple seasons back, Bill did a fascinating barrel cut-down test on a .338 Lapua Magnum rifle. Bill, a skilled gunsmith who runs 782 Custom Gunworks, cut down the barrel from 30″ to 17″ in one-inch increments. During the cut-down process, Marr measured velocities at each barrel length, shooting four rounds after each cut. As you’d expect, there was a huge change in velocity from long to short. Speeds were measured at the muzzle with a Magnetospeed barrel-mounted chronograph.
If you’re looking for max velocity with the .338 LM, go long. With 250-grain Sierra MK bullets, the peak velocity Bill measured was 2942 FPS at the full, 30-inch length. This decreased pretty steadily down to 2547 GPS at the shortest 17″ length. That’s an average decrease of 30.4 FPS per inch from 30″ to 17″.
Bill also tested 300-grain Sierra MatchKings. This is interesting because Randy Wise ran 300-grain bullets (Berger Hybrids) in a 26″ factory barrel for his ELR record. Peak velocity was 2833 FPS at 30″, 2799 FPS at 26″, and 2492 FPS at the shortest 17″ length. Interestingly, velocity at 29″ was higher than at 30″ for the 300-grainers. Bill notes: “The 300 SMK load showed a slight increase from 30 to 29″. I’ve recorded this in other tests and it seems to be more common with a heavier load. I suspect it is primarily due to the small sample sizes being used along with the relative proximity of muzzle velocities in adjacent lengths.”
At each new (shorter) barrel length, velocity was measured with a MagnetoSpeed chronograph using two different loads, 250gr SMKs with H4831sc and 300gr SMKs with Retumbo. Four shots were fired at each length with each load, a total of 112 rounds.
Load #1: 250gr Sierra MK, Lapua brass, CCI #250 primer, H4831SC, OAL 3.720″.
Load #2: 300gr Sierra MK, Lapua brass, Win WLRM primer, Retumbo, OAL 3.720″.
.338 LM Barrel Cut-Down Test Results Summary
.338 Lapua Magnum with 250gr Sierra MatchKings
After shortening the barrel from 30″ to 17″, total velocity reduction for the 250-grainers was 395 FPS, an average loss of 30.4 FPS per 1″ cut. The amount of velocity loss per inch rose as the barrel got shorter, with the biggest speed reduction, a loss of 55 FPS, coming with the cut from 18″ to 17″.
Start Velocity: 2942 FPS | End Velocity: 2547 FPS | Average Loss Per Inch: 30.4 FPS

New Cartridge, New Rifle for the King
Paul Phillips is the reigning King of 2 Miles. The founder of the Global Precision Group, Paul is one of the top ELR marksmen on the planet. He has also been a team-mate of past K02M winners.
Paul recently put together a new rifle for the 25-lb max, .338 caliber-or-under ELR Class. This is chambered for the 33XC, an efficient new cartridge devised by 11-time National HP Champion David Tubb. With promising initial testing at 500 yards, it looks like Paul’s 33XC project will be a success. The rifle’s first match will be the NRA Extreme Long Range Championship, to be held August 21-23, 2019 at Camp Atterbury, Indiana.
Paul reports: “The 33XC is ready for the NRA ELR Nationals. I have tested loads from 3100-3450 FPS and and will settle on a load around 3250 FPS [which is] my most accurate load so far. The Peterson Cartridge brass is really working well.”
Paul states he would like to look for a higher node from 3300-3400 GPS: “Next stop is with the Applied Ballistics LLC mobile labratory and radar testing with a PDM for the Nationals.” Paul cautions: “I encourage everyone to start low and work up. Every chamber, barrel, and components are a little different.”
During initial testing, Paul’s 33XC put three shots in 0.27″ at 100. Then, at 500 yards, the rifle produced a 3-shot group around 1/3-MOA with just 1.22 inches of vertical. That’s pretty impressive for early testing. Paul will also be trying some Berger bullets soon. When he determines the most accurate load, Phillips will stretch the rifle’s legs, shooting out to 2500 yards and beyond.
Quote: “The Cutting Edge Bullets are not the highest BC but they are very stable and consistent at ELR (sub-sonic) ranges and that’s the most important factor in finding the best ELR bullet. I actually test all my bullets at sub-sonic speeds to make sure they are consistent and stable. Finding a good load at 500 yards is just the first part. The real test is shooting them at sub-sonic speeds and see how consistently they group. This is what gives you the highest percentage to impact at 2 miles and beyond.”
This rifle features a BAT action mated to a 34″ Bartlein barrel chambered for David Tubb’s new 33XC cartridge. Paul Phillips is currently running Cutting Edge 275gr Lazer solid bullets. Paul notes: “I also have a .338 Lapua Magnum barrel and 300gr Berger bullets for the restricted class in France.” Paul gave special thanks to Alex Wheeler for doing the metal work and Alex Sitman for doing the bedding.
Rifle Component List
Action: BAT Machine CTH dual-port action
Trigger: Bullet Central Bix’N Andy
Barrel: Bartlein 1:8″-twist barrel (34″)
Chambering: 33XC for Peterson brass
Stock: McMillan A6 Super Mag, Bedding Alex Sitman
Scope: Nightforce Optics 7-35x56mm F1 ATACR.
Bipod: Duplin Rifles
Paul Phillips notes: “Alex Sitman has been bedding rifles stocks for most of his life. I believe that [bedding] is a very important … to keep consistent accuracy and repeatable zeros after traveling all over the globe.”
Even with the TacomHQ Charlie Tarac scope prism in place, the rifle makes the 25-pound weight limit with Duplin Rifles bipod. Paul says: “I love it when a plan comes together!! I’m under by 2 ounces!”
About the 33XC (eXtra Capacity) Cartridge
David Tubb invented the 33XC cartridge because he thought the CheyTac cases were too much trouble — requiring a larger action, oversize presses, and ultra-expensive dies. The 33XC was designed to fit .338 Lapua Magnum-size actions and use normal reloading presses.
The 33XC (eXtra Capacity) has 137.5 grains of H2O capacity with over 125 grains of usable powder capacity while leaving the 0.393″ neck unfilled for bullet seating.
The 33XC has a .338 Lapua Magnum lineage. Think of it as a better, 35°-shoulder .338 LM. David explains: “The 33XC uses standard reloading dies along with a 7/8″ x 14 TPI reloading press. There is no fire-forming — all case ‘improving’ has already been done with a production case that has 20 grains more powder capacity, 35-degree shoulder, and longer neck compared to a .338 Lapua Magnum. This puts the various .338 Lapua wildcats and the Rem Ultra Mag Improved into the ‘also ran’ category. They simply can’t compete with the velocities attainable with the 33XC.”
The 33XC is based off of a .580″ bolt head. Tubb states that “A fired case will extract with little effort when using a properly-polished chamber with a maximum powder charge after resizing with the Superior Shooting Systems FL sizing die.” Tubb’s 33XC die reaches the case head which is important for accuracy. Peterson Cartridge produces the 33XC brass for Superior Shooting Systems. This high-quality brass costs $115 for 50 cases (or $2.30 per case), and can be purchased directly from Superior Shooting Systems.
Yet another .300 Blackout disaster. Unfortunately, that .300 Blackout cartridge can fit in a .223 Rem chamber. Shooting a .308-caliber bullet in .223 bore is a recipe for disaster.
The .300 AAC Blackout aka “300 BLK”, is a compact 30-caliber cartridge designed to work in AR-15 rifles. It has a shorter cartridge case to accommodate the bigger 30-caliber bullet while still fitting in a standard AR-15 magazine. Unfortunately, that’s the danger. A careless shooter can toss a .300 Blackout cartridge in with .223 Rem rounds without noting. And because the case-head size is the same as the .223 Rem (5.56×45) the rifle’s bolt assembly will happily chamber and fire the .300 BLK round. Problem is, that forces a .308 diameter bullet down an undersized .223-caliber bore. Not good!
This images were provided by Tactical Rifle Shooters on Facebook. The message was clear: “Don’t try to run 300 Blackout in your .223/5.56mm. It won’t end well. The problem is identical rifles and identical magazines but different calibers.”
For those who MUST have a .300 Blackout, here are some things you can do:
1. Use different colored magazines for .300 Blackout vs. .223 Rem.
2. Fit all your uppers with caliber-labeled ejection port covers.
3. Mark .223 Rem upper handguards with the caliber in bright paint.
4. Mark all .300 BLK Rounds with heavy black marker.
Comments by Folks Who Viewed these .300 Blackout Disaster Photos:
“The .300 Blackout is simply a badly-designed round. A properly-designed round would have had a feature in the shape that would have prevented cross loading in the first place.” — D. Santiago
“I almost made that mistake… I had a magazine of 300 BLK inserted in my .223/5.56 all night. Fortunately, I never pulled the trigger. Once I realized the mistake, I almost got ill. [After that incident] I no longer own a 300 BLK.” — B. Welch
“Happened to me hog hunting from a helo. Gun exploded in my face.” — B. Hood
“Fire-forming projectiles [is] so wrong in centerfire!” — M. Stres
“Had some dude come into the store the other day wanting .300 Blackout ammo to shoot in his 5.56 AR. It took 15 minutes of explaining for him to understand you got to have a .300 Blackout Upper!” — R. Williams
RCBS has introduced a new series of MatchMaster Competition Dies. These are available in Full-Length Sizing, Neck Sizing, and Seating configurations. These new MatchMaster dies are notable for four features:
1. The Competition Seating Die has a “view-port” for the bullet.
2. The Competition Seating Die features a free-floating, self-centering bullet-seating stem.
3. Expanders are titanium-nitride coated for reduced friction. Both the Neck-Sizing and FL-Sizing dies come with TiN expanders for smoother case extraction and reduced brass build-up on the expander.
4. RCBS is offering its own precision-machined Neck Bushings.
No More Mashed Fingers When Seating Bullets
RCBS notes: “Reloaders will love that they can end smashed fingers and misaligned bullets with the specially-designed bullet window [on the Seating Die]. And users can fine-tune any load … with the micrometer-adjustable, free-floating, self-centering bullet seating stem.”
RCBS Product Manager Will Hemeyer explained that the new Competition Seater is a game-changer. “What sets the MatchMaster Seating Die apart from the competition is a bullet-seating window with bullet-retaining system. Simply place the bullet in the window and raise the case into the die to seat the bullet. Couple this with a micrometer-adjustable, free-floating, self-centering bullet-seating stem and the MatchMaster Seating Die is easily the most accurate bullet seating die on the market.”
Why Use Expander with Bushing Dies?
Some viewers of Gavin’s video asked if an expander is superfluous when using neck-bushing dies. The answer is “it depends”. The bushings reduce neck diameter from the OUTSIDE. The expander should make the INSIDE of the neck perfectly round. Some hand-loaders prefer to take the necks down a couple thousandths below final loading diameter, then finish the job with an expander. That ensures the INSIDE of the case neck is perfectly concentric. This can be particularly useful for brass that has somewhat inconsistent neck-wall thickness. Bottom line, you can run these dies without expanders if you want, but that option is available. The expander is also removable so the assembly can be used for de-capping only.
MactchMaster Neck-Sizing Only Die
The MatchMaster Neck Sizing Die Set also uses RCBS neck bushings to control neck tension while not changing the body dimensions of fired cases. Frankly we strongly recommend that you full-length size your rifle rounds, but we acknowledge that some hand-loaders prefer to neck size for some applications. The MatchMaster Neck Sizing Dies do include a titanium-nitride coated expander, just like the FL-sizing MatchMaster dies.

A couple seasons back, Bill did a fascinating barrel cut-down test on a .338 Lapua Magnum rifle. Bill, a skilled gunsmith who runs 782 Custom Gunworks, cut down the barrel from 30″ to 17″ in one-inch increments. During the cut-down process, Marr measured velocities at each barrel length, shooting four rounds after each cut. As you’d expect, there was a huge change in velocity from long to short. Speeds were measured at the muzzle with a Magnetospeed barrel-mounted chronograph.
