see my reply to 2-piper. this is exactly the potential disaster that can result in the use of the high heat, bone charcoal process to recolor a shotgun receiver. the gun becomes a potential bomb, without proper tempering of the metal after the coloring process is completed. the high heat bone charcoal process may work fine for some winchester rifle receivers, but it should never, never be used on a shotgun receiver.
