Drew,
Well, there is that, but, from where we are today, long removed from the manufacture of these old guns, the mechanisms that hold them shut and the very old wood they are stocked with, goes hand in hand with concern for the barrels.
My initial post had to do with why a 2 3/4” round carried CIP approval with a 1 1/8th ounce load, and it seems MODERN proof in England does not concern itself with the weight of the charge. Fair enough. You learn something new every day. Thanks.
I’ve no English guns at the moment to concern myself with. Again, based on Bell’s research, the old Halifax, .050” walls proofed at French single proof, with 2 1/2” chambers, originally cut for waxed paper cases, will happily digest them, I’m sure. The pressure won’t be out of spec for that gun, and the pressure rise from a 2 3/4” round in that chamber will be negligible. The Spanish double has 3” chambers. The Beretta O/U has 2 3/4”, with standard Italian proof.
They will work in everything, here.
Best,
Ted
