Fiocchi 62 gr subsonic 1050 fos
Tested with 2 pistols and 2 SBR rifles using 2 different suppressors and a Xero C1 pro chrono Ammo fed flawlessly in every configuration. The SBR had a 12 and 10.5 barrels. Unfortunately the extra barrel length exhibited higher velocities of 1137fps and produced very audible secondary sound. If not for this I would have rated it a 5. Since most folks will likely use this with a pistol and can combo, it’s still a great choice. Don’t waste money if using a longer barrel.
