Fiocchi Hyperformance SBR Features Fiocchi Hyperformance SBR ammunition is built around a powder specifically tested and selected for use in barrels ranging from 7.5 to 11.5 inches in length a range that covers most short barreled rifles patrol carbines and arm-brace pistols chambered in .300 AAC Blackout. Achieving a 100 percent powder burn in these shorter barrels reduces the muzzle flash and sharp report that often come from standard ammunition fired out of a truncated barrel. The 125 grain Super Shock Tip projectile is selected to deliver reliable expansion and terminal performance even at the reduced velocities typical of short barrel platforms. A muzzle velocity around 2225 feet per second keeps the round effective at realistic engagement distances for this class of firearm. Brass cased construction keeps the load compatible with reloading equipment for shooters who want to recover and reuse spent casings after a range session. Because the powder and bullet combination is purpose built for shorter barrels shooters running an SBR or braced pistol get more consistent terminal performance than they would from ammunition designed around full length rifle barrels. The load is also rated safe for use with a suppressor giving owners flexibility to run their short barreled platform quietly without sacrificing the tuned ballistic performance. Packaged 20 rounds per box Fiocchi Hyperformance SBR gives short barrel shooters ammunition engineered specifically for their platform rather than a generic rifle load.
