Sunday GunDay: New 33XC Rifle for Reigning King of 2 Miles
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.

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.
