Overview
The PMC X-TAC 556X is PMC's mil-spec M193 equivalent, loaded to full 5.56 NATO pressure specifications rather than the lower-pressure .223 Remington standard used for the PMC Bronze line. That pressure difference matters: the X-TAC pushes its 55-grain FMJ boat tail to 3,270 fps from a 20-inch barrel, roughly 70 fps faster than Bronze, which ensures proper gas system cycling in carbine-length and mid-length AR-15s even when new or slightly undergassed.
Manufactured by Poongsan Corporation with the same military production standards applied to their South Korean military contracts, the X-TAC delivers reliable lot-to-lot consistency for bulk M193-style training. The brass is fresh and reloadable, and the clean-burning propellant keeps gas ports cleaner during longer range sessions.
For shooters choosing between PMC Bronze and X-TAC, the decision is simple: if you're running a bolt gun or just punching paper at 100 yards, Bronze saves money. If you're training with an AR-15 and want NATO-spec velocity from a current commercial load, the X-TAC is worth the modest premium.
