Took my P22 to the range Jan 5 and 9. Expended 300 rounds of Remington hi-velocity HP and solid point. There were no stoppages or FTFs. I just added oil after about 200 rounds. The pistol was fairly accurate even at 20 meters, where I managed to hit Alpha 18 out of 20 rounds. So far, I've put in 800 rounds through it. There was a report however, that a shooter using a suppressed P22 damaged his suppressor because the slug "jammed" inside. He was allegedly using CCI brands. Not sure if he was using hi-vel rounds or subsonic rounds.
