I have a late 1940's box lock Boswell 12g double gun that has become very slightly loose in the action. Holding the gun by the stock with or without the forend in position and shaking it from side to side creates a little movement between the chamber face and breech face. I've held the gun up to a fluorescent light and cannot see any light coming through the join between the breech face and barrels.
My gun has a fixed hinge pin that can't be replaced. Another alternative that I've read about is laser welding of the hook that fits around the hinge pin to build this area up. I've also been told by a reputable source that if laser welding is done, within about 3 months of use the gun will work loose again at this point and isn't recommended.
Any thoughts or suggestions would be appreciated.
