338 ARC
The BIG Little Cartridge That Packs a Punch
Purposefully designed for hard-hitting subsonic performance, the 338 ARC delivers 1.5 times more energy than the 300 Blackout Subsonic. Engineered for consistent pressure, the 338 ARC provides reliable cycling with both supersonic and subsonic loads. Featuring the 307 gr. SUB-X® bullet in the Subsonic line and the 175 gr. HP in Hornady BLACK, the 338 ARC represents the ultimate 338 cartridge that fits in the AR 15 or micro-bolt action.

Just like with 6mm ARC and with 22 ARC, the 338 ARC uses the same 6.5 Grendel Type II bolt face or bolt carrier. If you're already invested in these cartridges, it's simply a barrel swap with your existing BCG.
