The .375 EnABELR Cartridge — Big and Fast

The .375 EnABELR cartridge is slightly shorter than a .375 CheyTac so it allows the round to mag-feed. Applied Ballistics is currently using brass made by Peterson. The .375 EnABELR has achieved impressive velocities — 2990 FPS — with prototype Berger 379-grain solid bullets fired from a 1:7″-twist 30″ barrel. Applied Ballistics may also test 1:8″-twist and 1:9″-twist barrels. READ Bullet Testing Report.

The .375 EnABELR cartridge was designed to offer .375 CheyTac performance in a slightly shorter package: “The problem with the .375 CheyTac is that, when loaded with the highest performance .375 caliber bullets (379-407 gr Berger Solids, and the 400-425 grain Cutting Edge Lazers) the round is not magazine feed-able in any action that’s sized for CheyTac cartridges.

“Knowing the .375 CheyTac produced substantial performance, and that it was just too long for magazine feeding, made it easy to converge on a design for the .375 EnABELR. We just had to make the case short enough to achieve magazine length with the desired bullets, while adding a little more diameter to keep the case capacity similar to the .375 CheyTac. The resulting basic shape is quite similar in proportions to the successful .338 Norma Magnum Cartridge which, interestingly, was selected as the cartridge for General Dynamics Lightweight Medium Machine Gun (LWMMG).”

The .375 EnABELR cartridge was developed to offer magazine feeding capabilities with the highest-BC solid bullets available. Applied Ballistics observes: “The best magazine is one that retains the cartridge shoulder and doesn’t allow the tip of the bullet to impact the front of the magazine during recoil.” Cadex Defense has designed magazines that fit Cadex’s bottom metal and chassis for the EnABELR line of cartridges which allows for maximum magazine fed performance. These mags are beautifully made, but they will be very EXPENSIVE. Expect to pay about $275 per magazine — what the Cadex 375/408 CheyTac magazine currently costs (Product Code: MAG4300, USD $273.95).

Q: Is this different than Cadex’s regular CheyTac magazine?

A: Mitchell Fitzpatrick of Applied Ballistics Weapons Division replied: “Yes, the ribs that retain the shoulder are moved back to hold the case back and prevent the bullet tip from hitting the front of the magazine. We had been playing with inserts welded into place, which worked great, but dedicated mags directly from Cadex was the ultimate goal.”

“CADEX and Applied Ballistics. Two companies taking ELR seriously and trying to get that last 1-2% of performance out of the system. Keep up the good work!” — Mark N.
