ed when you first started posting here you or your gun mechanic were using a high heat acetylene torch method. There were birdseyes and many other tell-tales. You probably harmed the case hardening of the doubles that were done that way. Drew Hause has pictures of your torched colors on his website.
After your first big battle here over case colors you (or your gun mechanic) switched to what is essentially the Ithaca/Perazzi method with low heat by torch and a chemical application. I think that that method does not harm the case hardening. No harm, no foul in my opinion.
I agree with you that the the bone charcoal method may cause warpage of the action. But a competent gunsmith can put it back right.
I wouldn't have a gun case colored by either the chemical/low heat or the bone charcoal method. I would leave it as is. I would never, ever, ever harden one with just an acetylene torch the way you (or your gunsmith) used to do it.
