Bruce according to the Parker Proof Load Table you reference, your numbers come from "Theoretical Service Pressure Pressure Limits...." on the left side. As you can see that would mean 2 3/4" 12ga guns were built to handle 125% greater pressure than 2 5/8" chambered guns. That looks like a little chink in the armor that 2 5/8 chambers were meant for 2 3/4 inch shells to me.
