Fiocchi Hyperformance SBR ammunition in .223 Remington (brand part no. 223SBRD) loads a 77-grain Sierra MatchKing hollow point boat tail, precision-tuned for shooters running short-barreled rifles, patrol carbines, or arm-brace pistols. Fiocchi selects each projectile specifically for barrels between 7.5 and 11.5 inches, then tests powders for a full burn that delivers low muzzle flash, a diminished report, and consistent velocity out of a shortened barrel. The Sierra MatchKing’s concentric jacket and boat tail base are built for the accuracy competitive shooters demand rather than hunting-style expansion. Safe for use with suppressors, this rifle ammunition is tuned for the platform, not just the caliber.
