Hornady Subsonic 338 ARC 307gr Sub-X - Box or Case

The Hornady Subsonic in .338 ARC is purpose-built rifle ammunition designed around a heavy 307 gr Sub-X polymer-tipped bullet that exits the muzzle at a hushed 1050 fps - well below the speed of sound - for dramatically quieter shooting through a suppressor (no supersonic crack) and a reduced flash signature when fired unsuppressed. Each round produces 752 ft lbs of muzzle energy, making it ideal for AR-15 rifles chambered in .338 ARC.

Every cartridge is assembled with reloadable brass cases and a Boxer primer, loaded around powders optimized specifically for subsonic use to deliver a clean, low-flash burn and reliable function. The Sub-X projectile pairs a polymer tip with a lead core and copper jacket engineered to expand at the lower velocities typical of subsonic flight, making it a top choice for hunting, training, and quiet-range work in any .338 ARC rifle.

Shipped in a 20-round box, with 10 boxes per case (200 rounds total) for extended range sessions.
