One other question is: if the round is charged to a point higher than it is designed to handle, will it matter much in the long (or short) run how much case support it has?
I would venture: it will blow the case, regardless, because the pressure is past the point of what the case can handle (A + B = C, so Z is irrelevant).
I wonder if the difference between blowing out mags and mag releases, etc., and splitting the barrel, is due to how much bottom support the chamber has.
More support = split barrel, less support, blown out parts. Thoughts?
