Atomic .308 Winchester 175gr Subsonic BTHP, 50-Round Box

Atomic .308 Winchester 175-grain Subsonic Boat Tail Hollow Point ammunition (brand part no. 00430) is built for suppressed rifle shooters who want their .308 to stay quiet without giving up accuracy. Atomic loads a Sierra 175-grain BTHP bullet to a rated 1050 fps, keeping the round well below the speed of sound while the boat tail profile and streamlined meplat hold a consistent flight path downrange. Because this is a match-style hollow point built for accuracy rather than expansion, it suits suppressed target shooting, precision practice, and low-noise range sessions better than hunting. Every box ships in a reusable plastic case, and Atomic assembles the load entirely in the USA.
