So I've had this 16 gauge given to me by my Dad years ago sitting in my gun case and decided to start shooting it yesterday. The first day shooting skeet it locked up pretty bad coz it I didn't think about lubing it before taking it out. A guy at the range had some lube to put on it and it seemed to work ok after that. In total, we spent 2 days shooting skeet and put about 175 rounds through it. Today, the 2nd day, much of the time, if I tried to do anything but singles with it, the extractor would fail and a jamb would happen. If I did only singles, it worked, but towards the end of the day it was just really rough and felt like it was going to lock up at any time even if only singles were put through it. Looking for ideas/suggestions on what to do with it at this point. Anyone have experience with this model?
