Okey first I had to replace the extractor, ecxtractor spring and plunger and fireing pin (flat style) and all had to be filed alittle to fit or work properly or I think it is. It cycle's live rounds fine but when I shoot (rem balk 22 which I will never buy again miss fire's in every 22 I own) the case gets stuck in the chamber. Cleaned very well like I said live rounds just slide in and out. So the question is, What round should I shoot in this old of a gun? Or is this not the problem? Thanks for any info I looked at this gun not working since I was 5 and now 44 and am kind of proud I have it shooting again but want it cycleing while shooting then I will be done with it with a smile.
