This video tests new Fiocchi 300 Blackout subsonic ammunition, specifically 220-grain boat tail hollow points. Chronograph data was collected from both a 16-inch barrel and a short-barreled rifle (SBR), revealing minimal velocity differences between the two despite an 8-inch barrel length disparity. The presenter notes that the powder appears to be optimized for shorter barrels, with potential for short-stroking issues in SBRs with certain buffer setups.
