Unclenick, my load used 46 some odd times in that .308 Federal brass case was a Fed 210 primer under 42 grains of IMR4895 topped by a Sierra 165-gr. SBT hunting bullet miced at .3081" and shot in a barrel with a .3078" groove diameter in front of a SAAMI spec chamber. My guess was/is the peak pressure was about 51 to 52 thousand cup, 60 thousand psi
