So I've had this baby about a month and I finally go to hit the range with it. I felt every thing was going well. I was using CCI Mini Mag as that seems to be the prefered ammo which ive seen on this forum prior to purchasing the P22. So after 100rds I started to notice the ammo was impacting very erratic at best. Some left, some right. I went into a very supported position and carefully squeezed off a mag of 10. no joy in the 5 inch taget at 7m. I packed up and headed home to clean. While conducting a simple cursory inspection of the out side of the weapon after clearing, I noticed extreme chipping and scuffing of the metal around the barrel tip. Upon further inspection I noticed the scuffing and chipping extended into the barrel, approx. 1/4in. I thouroghly cleaned the weapon prior to use and made sure it was fuction checked and well lubricated. (not dripping but well lubed). Im curious if anyone has any idea. Right now i can only assume the barrel failed. I do have 16 years in the Infantry and am a Master Gunner. Ive been around guns since I was 8. its almost like the barrel was simply crumbling as I shot.
