I have an old Colt Ace .22 conversion kit that my grandfather gave me. After a lot of cleaning and a new recoil spring, I thought I had it running pretty well. Not 2,000-challenge well, but consistent through a range session as long as I cleaned it when I got back.
But now it's having a serious jamming issue. Somehow it ends up with the new round failing to feed so hard that the unfired .22 gets bent over, and the rim gets jammed into the front feed lips of the magazine. It is locked up so hard that the only way to extract the mag is with a rubber mallet or a set of pliers.
At first this only happened with a new metalform magazine I had bought for it, when I loaded it near full capacity. I assumed it was a bad mag and kept using the 30-year old one that came with the gun. But it happened twice yesterday at the range with the old, previously reliable mag.
I don't even know where to start diagnosing this. Does anyone have any ideas?
Thanks.
