I'm not a big 22 rimfire guy (although that might change, I need the practice!) so I don't have zillions of rounds down range, but I did have my first case rupture issue yesterday.
Armscor 36gr plated hollow points, working very well in my TS .22 Glock conversion but then the gun went "pfffft!" instead of "bang!". Lotta smoke coming out of the frame/slide and I could feel some crap hitting my hand. Cleared it out, nothing in the barrel and everything looked intact and I wasn't bleeding so I continued shooting. From what I can tell, no damage and the gun ran fine the rest of the day.
