You cannot compare the military measurement, which is 52,000 PSI with the copper crusher gauge to the SAAMI 62,000 PSI which is a piezoelectric transducer gauge measurement.
Military measurements in CUPs VS SAAMI in (piezo) using other calibers such as the 30-06 show about the same spread.
In reality, Max pressure for .308 and 7.62x51 are about the same.
DIE RUMOR DIE!
Now this makes sense and basically goes with what I had always been told. The difference is that a lot of commercially available .308 ammo are loaded towards the low-end of the pressure spectrum to mitigate the big "L". This practicereduces the possibility of causing some cheaply made commercial gun to go "boom". Not much of an issue for the military.
