Went to the range today and had some disappointing results! I was shooting Federal Champion 510s, and could not go through a clip without a problem. Ejection problems to say the least. Every extraction issue I had, had to do with the brass case still halfway into the chamber. It would happen at least once from a 9 shot clip. Brought it home and had a look. Everything looked good. Manually fed both a spent and live round into the chamber (after taking it apart) and found that each brass case did not stick. I have replaced the extractor with a stock factory one with same results. Feed ramp is smooth, clips are good. Ammo not binding in them, and the gun was cleaned from my last time out. I am thinking of putting in the volquartsen extractor but Midway and others say that the one they have only fit the 10-22, Mark ll and Mark lll. Will this one work in my gun? And more importantly, do you think it will fix the problem?
