I would have cut the barrel and recrown if it is a sporter but it is in military configuration and front sight is there. Checked into the tool rental places, they don't have any tool to counterbore muzzle. Did my search on the web, not much info found but did came across a posting that he uses a handdrill and drill bit to do it and was fine. No detail mentioned. My thought is the drill bit should follow the bore if I start with a drill bit just a tad larger and progressively increase the size. How much oversize needed? Not sure how to clean up the burrs afterwards but think I can make a rod to go into the bore to recrown. I will shoot it first before I do anything stupid. It is an Izzy 308 Mauser and I like to keep it in military configuration.
