Mark, if a Hunter Arms Co., the 10 and 12 gauge would be about the same. Syracuse guns heavier wall thickness.
I start my wall thickness readings at 5" and after that every 3" until 23". I don't think it is important to go beyond that and from what I have read about pressures, after about 16" they are down to 500-600 psi if they started at 10,000 which I never go that high to begin with.
