308 and 7.62X51

The loading manuals make no distinction between the two, but the nato round pressure is supposed to be 50,000 C.U.P. and the 308 is around 52,000 C.U.P. and, furthermore the headspacu guage for the nato is slightly more allowable than the 308.
Great deals have been made about this but there is no difference for all intents and purposes.
