22LR Bad Ammo??
You have an ammo problem is my guess. The lube or coating on each bullet/brand is different. Lube/coatings can have an effect on accuracy and leading.When testing 5 different brands of 22lr in my Mossberg rifle, one lot caused a wild swing in point of impact and accuracy. More testing showed a conflick between lubes. My S&W m17 22lr when shooting one brand left a ring of lead in the barrels rifling. This was without switching between brands. After cleaning all lead out, i test fired with the defective ammo, watching as the lead build up, formed the same ring. Knowing the history of my revolver was proof enought for me that it was an ammo problem. Always clean before switching brands of 22lr ammo to test. I have seen case heads bulge on firing that would push the fired casing off the bolt face in a auto, bad ammo. Another was some Rem. walmart bulk, the bullets were deformed. Looked like the bullet is swaged on loading into the brass, bad ammo. Do more ammo testing before you send the firearm back for repair.
