Hrndy Subs 338arc 307gr Sub-x 20/200

Hornady Subsonic 338 ARC 307gr Sub-X ammunition delivers suppressed rifle performance engineered for operators and precision shooters who demand accuracy below the sound barrier. Subsonic loads eliminate the supersonic crack while maintaining consistent terminal performance, making this cartridge ideal for tactical applications, hunting with sound suppressors, and training where noise signature matters.

The 338 ARC platform offers a compact, modern alternative to larger magnum cartridges while delivering rifle-class ballistics in an intermediate form factor. The Hornady Sub-X projectile is purpose-built for subsonic velocity regimes, engineered to expand reliably and transfer energy consistently at velocities typically 200–300 fps below standard supersonic loads. High-quality cartridge cases and Hornady's precision primers ensure consistent ignition and chamber pressure, critical factors when operating at subsonic velocities.

Law enforcement tactical teams, military designated marksmen, and civilian shooters running suppressed 338 ARC rifles will benefit most from this load's subsonic design and proven Hornady accuracy standards. This ammunition performs optimally when paired with sound suppressors rated for 338 ARC, which provides enhanced performance in tactical and hunting scenarios. Each box contains 20 rounds, ensuring you have ample ammunition for your needs.
