If it did then it sure didn't start life as a 4 bore. It's bored out from something smaller, that's why the chamber walls are so thin. And yes, for the pressures that you're dealing with on a 4 bore charge, I'd say that 3/16 is just a bit over tinfoil.

Jim Kelley? Is he an expert on big bore British shotguns? If he is then I'd very much like to speak with him as I like to discuss that sort of thing. Tell us all about him, how many of these has he worked on in the past?

If you want to talk about envy shall I send you pics of my Churchill double 8 gauge that weighs about 16 pounds and has chamber walls approaching cannon barrel thickness? How about pics of me shooting driven ducks with a Holland & Holland double 4 gauge in England? No George, I'm not even slightly envious of your bored out double rifle.
