Pressure depends on the burn rate of powder used, the hull itself, and wad used--I don't think their is any mathematical formula to calculate pressure, and it must be measured directly. At least that is what I believe to be true, not a physicist or engineer, however.
I noticed on precision site that they will not test factory loads. I don’t understand why that would be.. I’d be very happy to pay thier $25 fee to test 5 shells..
