Atomic 308 Winchester 175gr HPBT Subsonic Rifle Ammo - Box or Case

The Atomic 308 Winchester Subsonic is a match-grade rifle load built around a 175 grain Sierra MatchKing Hollow Point Boat Tail (HPBT) projectile moving at a subsonic 1050 fps from the muzzle. Generating 428 ft lbs of energy with notably low recoil, this round stays under the sound barrier so it pairs naturally with suppressed rifle platforms and remains quiet enough for range training in noise-restricted environments.

Loaded in a reloadable brass case for consistent pressures and reliable performance, the Sierra MatchKing HPBT bullet is built for the accuracy and sectional density serious precision shooters demand. The boat-tail profile and hollow-point construction deliver a stable trajectory and tight groups at match shooting, range training, and long-range applications.

Your purchase options:

• Case - 500 Rounds (10 Boxes): Ten factory boxes for a full case of 500 rounds, perfect for high-volume training and match use.
