I've inherited a Winchester Model 97 12 gauge (circa 1945) from my father-in-law. It appears to be in fairly decent shape and I would like to use it for hunting. The one obvious flaw is a bubble/bulge at the final inch of the muzzle. I am looking to repair the barrel (shorten it an inch and recrown it) unless that's not a cost-effective solution. Obviously, if I'm going to hunt with it, it needs to shoot a reasonably tight pattern and I'm concerned that simply shortening and recrowning the barrel will leave me without any choke whatsoever . The other two alternatives that come to mind are shortening the barrel and fitting it with a screw-in choke or replacing the entire barrel. Any advice on these (or other) alternatives would be most welcome.
