.338 Federal


Considered by some ballistic experts to be the ideal cartridge for North American big game, the .338 Federal is also known for superb accuracy and stopping power in a controllable package.

The .338 exhibits impressive downrange ballistics comparable to 7mm Magnum or .338 Winchester Magnum class cartridges, with the added ability to fit in a lightweight short action semi-auto like our BILLet-AR rifles. The .338 Federal cartridge is based off of the .308 Winchester and uses the same receivers, bolt and magazines as its parent cartridge without any loss in capacity. These rifles utilize our lightweight, in-house machined BILLet-AR receivers and Wilson Combat Match-grade barrels. This rifle is further enhanced with our renowned custom features like our button-rifled Match-Grade barrels, MLOK® hand guard rail and crisp, reliable Tactical Trigger Units.

The rigid but lightweight BILLet-AR receiver with 14.7" barrel and pinned muzzle device of your choice is one of the handiest semi-auto big game rifles on the market. The .338 Federal is also offered in a medium profile 16" fluted and unfluted-barrel versions.
