I have had my barrel out of the stock for about 7 or 8 days while I was inletting my ramrod thimble and pipes. When I went to re-pin the barrel only 2 of the four pins went back in. The two at the muzzle end wont go. I can see light thru the holes and am guessing they are about .020 out of location. It seems the stock has moved on me. Any suggestions on what I should do would be great!
