Because it is.

.308 Win is rated at 62,000 psi.
7.62x51 is rated at 60,200 psi.

Not a lot hotter, but hotter it is.
The difference between brands of primers. Well within the safety margin. Seriously, if you are worried about a 1800 PSI differential, you have a wall hanger, not a rifle.
Yes but, when you are dealing with an early Mauser which was proofed below 308 or 7.62 operating pressures, either reload, or make it a wall hanger.
