Triple, thats almost impossible to do. You really never see more than 30KPSI with BP or 777 or pyrodex. But with smokeless, its a different story. I would guess, I say guess, with his load, he went up in pressure over 90KPSI. Centerfires generally are less than 60K. When you reach max, the pressures get erratic fast. And so does velocity. So 5gr is significant. I would equate it to shooting 150gr of goex in a sidelock only able to handle 16KPSI with 90gr of goex. But thats just a guess.
