I have an 1892 Winchester in .25-20 WCF which I think is a candidate for a liner. There is still rifling visible, although it is eroded after 107 years. Jacketed bullets still make round holes in a target at 100, but a few rounds of cast, preferred bullet, and the barrel is very difficult to clean. Since the rifle has been refinished, which is a very good job, a liner does not hurt the value, and I am shooter not collector. Can a liner be installed so that the muzzle does not show the ring joint of the liner, such as a silver solder filler being used? Does anyone have a recommendation for a gunsmith that does this type of work?
