When a serious threat arises, top shooters go for PMC X-TAC. Designed and manufactured as if your life depended on it, all PMX X-TAC ammunition is tried and tested by military and law enforcement around the world. Carefully loaded, primed, and sealed, each X-TAC 5.56 NATO cartridge guarantees consistent velocity and energy for tighter shot groups and more confidence behind the trigger.

Available in supersonic (147-grain) or subsonic (200-grain) loads, all of our 300 Blackout rounds are sourced directly from Winchester and Armscor, a global military contractor serving units in the U.S. and overseas.
Armscor ammunition is also first-run produced in an ISO 9001-certified manufacturing facility. Winchester's 300 Blackout 200-grain loads feature a subsonic "power-point" tip and contoured jacket, guaranteeing expansion and knock-down potential at subsonic velocities.
