I've put over 2000 rds through mine, unplated, unjacketed, plated and jacketed. They all went through the barrel just fine. A few hiccups with the first 200 or so Winchester M22s, but it went through the next 300 of them just fine. I will say though, that I only shoot 1200 fps or higher ammo. Haven't tried subsonic with my M&P22.
