Product Info for Atomic Ammunition Subsonic .308 Winchester 175grain Boat Tail Hollow Point Brass Cased Rifle Ammunition

Atomic Ammunitions .308 Win 175gr subsonic ammo turns suppressed .308 rifles into quiet training and practice platforms. The 175gr hollow point boat tail load stays below the sound barrier, preserves practical accuracy, and fits suppressed precision work at sane distances.image

The 175gr HP BT is a proven match-grade projectile that delivers excellent accuracy even at subsonic velocities. In suppressed .308 platforms, noise drops to 120-125 dB hearing-safe and dramatically quieter than the 160+ dB of unsuppressed supersonic fire. The 428 ft-lbs of muzzle energy provides effective terminal performance for close-range applications, and the .308s universal availability means you can use the same rifle for full-power and subsonic loads by simply swapping magazines.

Every cartridge is loaded with components: new brass cases, precision-weighed Hodgdon powder charges, and match-grade 175gr HP BT projectiles. Hand-inspected for consistent performance.
