This may seem like an odd question, but a long time ago I read or heard talk of using oiled semi dirty/clean black powder patches to wipe down the outer finish of rifles and/or pistol for dulling the blued finish, thereby making the finish look more antiqued. I love the antiqued look of the old 76's and 86's, but unfortunately, don't have the time to wait around 100 years for my Uberti's to get that look naturally. Just wondered if there was any truth to this method.
