Hornady Subsonic 338 ARC 307gr Sub-X – 20 Rounds

Hornady Subsonic 338 ARC ammunition features a 307-grain Sub-X bullet engineered for reliable expansion at subsonic velocities. The Sub-X projectile uses Hornady's Flex Tip technology to initiate expansion even when impact velocities drop below the sound barrier, making this load ideal for suppressed hunting applications where sound signature and terminal performance both matter. Designed to stay subsonic in standard barrel lengths, this cartridge delivers heavy bullet weight and deep penetration on medium to large game.

This ammunition is optimized for bolt-action and AR-platform rifles chambered in 338 ARC. Loaded in high-quality brass cases with temperature-stable powder and dependable primers. Available in 20-round boxes or 200-round cases for extended range sessions or hunting seasons. Suppressor-safe and optimized for sound reduction without sacrificing lethality.
