Bill, I don't want to steal this thread but can you explain that? I don't own a British gun nor do I expect to but, over the years I have been told that no one can work on a gun there without proofing it, or some such lingo. Anyway, my point is that their government has a set of, what seem like stringent rules, to insure safe gunning. On this forum there have been several discussions about what constitutes thin barrels and from my view the topic never had a true definitive definition to when they became "thin".
I would have thought a recent test from a certified proofing house would indicate safe barrels.
