Mystery solved!! I got sold some mil surp 54R by mistake and I didn't catch it. Ok. So my AK-47 has stumped me once again. The chamber looked way to small for a 7.62 and I happened to have some 5.45 sitting in a box in the basement. So, I decided to check the muzzle end and it would only go in a little. So I turn the barrel around and tried the other end. It wouldn't go in passed the shelf I think it's called? The widest part of the taper on the case. Also, the bolt is way to small for the 5.45. All I can think of is this AK got re-chambered? Any ideas? I'm gonna try to find a smith somewhere. I live in the boonies so it's not going to be easy.
