This video introduces Fiocchi's new 5.7x28mm ammunition offerings, including a bulk pack. Christian H. from Fiocchi details their production history and various ammunition types, such as 40-grain FMJ, 35-grain copper jacketed frangible, and 32-grain FMJ subsonic. The bulk pack is designed for range training and personal defense applications.

This guide details a practical test to demonstrate how the AR-15's gas block and tube assembly can affect barrel harmonics and accuracy. The VSO Gun Channel host, an expert firearms instructor, walks through firing groups with the gas system intact, removed, and reinstalled, using subsonic .300 Blackout ammunition to amplify potential accuracy differences. The results highlight that even components designed to be free-floated may not achieve true free-float status due to the gas system's interaction with the barrel.

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.
