Description

Hornady Frontier Cartridge ammunition is American-made and loaded using the same quality control procedures applied across Hornady’s broader production lines. The .338 ARC (Subsonic) 285gr FMJ load is specifically configured for shooters running suppressed .338 ARC rifles who require reliable subsonic performance — keeping muzzle velocity at 1050 fps from a 24″ test barrel to ensure the projectile stays below the speed of sound and delivers a reduced acoustic signature when paired with a suppressor. This load is well-suited for use with rifles such as the Ruger American Rifle chambered in .338 ARC, and is compatible with suppressors rated for .338-caliber cartridges.

Each round is built on a reloadable brass case with a military-grade Boxer primer and military-grade propellant, consistent with the Frontier line’s emphasis on reliable ignition and shot-to-shot consistency. The 285-grain FMJ bullet is a non-steel-core, target-friendly projectile suited for plinking, target shooting, law enforcement training, and hunting applications. At subsonic velocities, the 285gr projectile still delivers 698 ft-lbs of muzzle energy, providing meaningful terminal performance for appropriate game and barrier applications. Sold in 20-round boxes.
