Also... 7.62x54R is not a .308 diameter either. It's .310 to .312 as well. So is .303 British and the Japanese 7.7 Arisaka cartridge.

.308 (7.62x51, aka 7.62 NATO), .30-06 and .30-30 use .308 diameter bullets. So do all the current .300 <<insertbraggingrightshere>> whompem-magnum offerings.

But, since the velocities of each cartridge are going to be different, you're gonna want to optimize bullet weight and construction for the intended purpose of the rifle.
