[QUOTE="308win, post: 2143126, member: 102230"] Using your 50.6gr load and 3208fps that would give you a 106.3% case capacity and 87653psi!!! Max on the 7-08 is 60191, so I'm guessing you would have seen a little bit more than an ejector mark at the pressure. Going with the standard burn rate of H414 and 50.6gr of powder, your estimated pressure would still be in excess @ 69188psi. Either way, to hot of a load. Using the standard burn rate, your max load would be 48.6gr @ 70° estimated at 2909fps. Estimated OBT Node for your 22 inch barrel would be 46.6gr and 2782fps.
