RE: whats the difference between .308 and a 7.62mm X 39mm, or are they the same?
[quote]ORIGINAL: Nomercy
No, these two rounds are in NO WAY the same, nor interchangeable.
100% Correct

The 7.62x39mm is a soviet cartridge that fires a 0.311" bullet.
Wrong it is 7.62 mm or 30 cal. or 0.308"

The .308Winchester is interchangeable with the 7.62NATO, which are essentially identical in specs
True

and is an american derivative of the .30-06 based around a .308" bullet...
Wrong again. Both the 30.06 & the .308 fire the same .308" diameter bullet.
7.62 x 39mm = 123g. at 2300 fps muzzle vel.
.308 = 7.62( NATO) x 51mm = 150g. at 2800 fps muzzle vel.
30.06 = 7.62 X 63mm = 150g. at 2900 fps muzzle vel.
Stats. are from Federal Ammo. site based on simular common rounds.
Note: only one round aval. for 7.62 X 39mm
