I bought a second hand M77 in 7x57 (mid 80's by serial number).
I took it out to the range and it wont feed right, the round pops up out of the mag, but doesn't get picked up in the bolt face, it just sits in front of the bolt, and when you try to chamber the round the bolt doesn't go in far enough because the round isnt in the bolt face.
Anybody ever had this problem an know any fixes?
