Fiocchi Hyperformance SBR Features The Fiocchi Hyperformance SBR load pairs a 77 grain Hollow Point Boat Tail projectile with a powder charge specifically formulated to achieve complete combustion inside short barrels so shooters running SBRs and patrol carbines still get consistent velocity and pressure. At 2750 fps the load delivers flat-shooting performance that closely matches longer-barrel .223 Rem loads minimizing the ballistic penalty that typically comes with shorter barrel lengths. The boat tail profile also improves the bullet s ballistic coefficient helping retain velocity and accuracy at extended engagement distances. Because the powder is engineered for a full burn in barrels from 7.5 to 11.5 inches this load produces noticeably reduced muzzle flash and report compared to standard rifle ammunition fired through a short barrel an important consideration for night operations and suppressor use. The brass case is boxer primed and fully reloadable reflecting consistent quality control across every round in the box. Packaged 20 rounds per box this load gives owners of short-barreled rifles braced pistols and suppressed carbines a purpose-built option tuned to their exact platform.
