PMC‘s Bronze X-TAC line in 5.56 NATO (brand part no. 556M855MB) loads a 62-grain full metal jacket bullet at a listed 3,100 feet per second, packed here in a reusable 840-round steel ammo can rather than individual boxes. PMC manufactures X-TAC to the exacting specifications demanded by professional and military customers, and this loading delivers 1,323 foot-pounds of muzzle energy from a proven 62-grain bullet weight matched to modern AR-15 barrel twist rates. The steel ammo can keeps this bulk quantity protected from moisture and ready for long-term storage, then doubles as genuinely useful gear once it’s empty. For 5.56 shooters who want a serious bulk supply that stores as well as it shoots, this rifle ammunition is built for both.
