Forgive me, I was asking about English guns and English Proofs. I wouldn't know the first thing to do with an American gun. Not a fan. I guess that makes me one of those "self loathing Americans".

Point of Proof is 9� from the breach, all other measuring points are less important. The thickness and bore dia at that point is what counts and tells you if you have a gun or not. Over worrying about thickness at the oft measured thin spot of 8" from MUZZLE is pointless except to foster sleepless nights worrying about denting it down the line. Of much more interest to me is the minimum acceptable wall thickness at Point of Proof

Yes but we don't seem to have any standard minimum 9" from the breech.
I would prefer a standard minimum at the junction of the chamber/taper and/or 1 inch from the breech face as pressure falls away rapidly after this point.
I cannot help but wonder why the proof house is so hung up on bore diameter.
You are never going to blow up a barrel at the chamber because the bore has been honed out.
