There sure is.Originally Posted by mehavey
CUP * 1.516 - 17,902 = PSI.
Example: 52,000 CUP * 1.516 = 78,832
78,832 - 17,902 = 60,930 PSI.
308 Winchester currently holds two SAAMI ratings. 52,000 CUP and 62,000 PSI, and it isn't an accident.

Everyone on this Forum has direct access to the actual SAAMI standards of both CUP and PSI for individual cartridges.
USE THEM.... if you value your eyes and fingers.
