Now ed you posted this on this very thread yesterday:
sounds like you have never re hardened a shotgun receiver. well, neither have i. so, neither one of us really knows what we are talking about here, right?
And while I agree with you that you don't know what you are talking about here I don't understand why you continue to post about bone charcoal case hardening since you admittedly don't know anything about it.
And since we are repeating ourselves just about anything done incorrectly to the metal parts of a shotgun can screw it up. Including Mr. Landers doing something incorrectly to it.
And so you don't have to ask Dave still hasn't contacted me. If you don't believe me you can start a third Lorenzotti thread with the Gun Broker number and see.
Best,
Mike
