I have a set of 12 gauge damascus double barrels from a breech loader shotgun. Don't know what happened to rest of gun. At the chamber end, walls approximately 1/8" thick, guessing about same at forcing cone where would be cut. Then threaded for breech plugs and made into muzzleloader barrels if this is feasible. I know modern steel barrels have been used this way. Question is how safe would damascus be? Barrels are in good shape, no rust pitting. I have a 13 gauge double with damascus barrels that is about same thickness at breech plugs. Would fit barrels to that gun for extra set of barrels.
