Fiocchi Hyperformance SBR ammunition (brand part no. 300BKSBS) chambers the versatile .300 AAC Blackout cartridge with a 220-grain boat tail bullet, sitting at the heavy end of the .300 Blackout weight range. Fiocchi builds this Hyperformance SBR line on a brass case for reliable feeding and extraction across the AR-platform rifles and pistols this cartridge was designed around. The heavier 220-grain bullet weight and boat tail profile favor consistent, stable flight over the lighter, faster bullets used in standard-pressure 300 Blackout loads. Each box holds 20 rounds, with case packs of 10 boxes available for shooters who want a bulk supply.
