Fiocchi Hyperformance SBR Features The Fiocchi Hyperformance SBR load is precision-tuned with powders selected specifically to achieve complete burn from barrels as short as 7.5 inches minimizing muzzle flash and reducing report compared to ammunition designed for standard-length barrels. Each 220 grain ballistic tip projectile is selected to deliver optimal ballistic and terminal performance at the subsonic velocities typical of suppressed short-barrel platforms. This tuning matters most to shooters running barrels between 7.5 and 11.5 inches where standard-length loads often fail to burn cleanly and produce excessive flash and blast. By matching the powder to the shorter barrel Fiocchi keeps performance consistent across patrol carbines short-barreled rifles and arm-brace pistols alike. At 1075 fps this load stays below the sound barrier making it well suited for use with a suppressor for a quieter more comfortable shooting experience. The reloadable brass case gives shooters the option to recover components after firing.
