Maxim Defense SBA ammunition optimized for short-barrel rifles. Features 117-grain solid copper bullets with Tumble Upon Impact technology for superior terminal performance in close-quarter scenarios.
Short-barrel rifles deliver exceptional maneuverability in close-quarters situations, but they often sacrifice the velocity and terminal ballistics of their longer-barreled counterparts. Maxim Defense addressed this limitation by developing ammunition specifically engineered for SBR performance.
Working in partnership with Fort Scott Munitions, Maxim Defense optimized these loads to maximize ballistic effectiveness from shorter barrels. The result is ammunition that delivers wound cavities exceeding the performance standards of both conventional expanding and fragmenting projectiles.
The centerpiece of this ammunition is the TUI (Tumble Upon Impact) design. Rather than relying on expansion or fragmentation, these solid copper bullets are engineered to tumble through tissue, creating devastating wound channels. The TUI design remains effective all the way down to 500 feet per second—critical for short-barrel performance.
This ammunition represents a thoughtful solution for shooters who demand maximum terminal performance from compact, maneuverable platforms.
