30-06 pull through reamer

Fellow member was gracious to allow me to use his, great group of fellow Gun enthusiast here !

Sometimes if the barrel of chromium surfaced, it can not be reamed. One needs to check for that first. I ran into that with a polytech M14s. I was changing out the chinese bolt for a TRW bolt. We ended up take a little off the bolt face with a special diamond tool. That way both bolts still work with that gun.
