I hear you Keith. I was thinking in terms of hardening by quenching from above the steel's critical temperature. In this example, I believe, the gun part was quench hardened, but only the case. In theory, the base low carbon steel core remains relatively unaffected by the heat treat temperature changes.

Only conversation here, but I think, once a steel yeilds, even if the part hasn't broken, the hardness falls off rapidly. I don't think that type of damage can be corrected and returned to a ductile state that resembles the original wire example. I suppose short of tossing it in a smelter and starting over?

edit to add, ed, ya shud'a spoke up when your budy peed in a no go zone.
