Hi guys, maybe you can help me with a slight problem I've been having I bought a savage-made No4 rifle at a gun show, so no returns available. The bolt and the receiver numbers do not match, but I marked up the lugs and they look like they have pretty decent contact on both sides. One side is slightly better than the other (the long lug contacts slightly better) I did some shooting with it the other day, and for the first time since I bought it, and I have problems on primary extraction. I'm using MEN-83-8 surplus ammo which goes into the chamber with no problems whatsoever, and I have no problems extracting unfired rounds. When the round is fired however, I have problems getting the bolt to open. I have to smack it upwards to get it to turn all the way open, after which I can always get the case out. Fired brass does not go into the chamber easily, although some cases do go in easier than others, but it's a tight fit or requires a bit of a smack on the bolt. I assume the chamber needs to be polished, but I'm hesitant to do so without using the right tool to start with. Do you have any recommendations for honing tools? Am I on the right track here or is there something else at play?
