    I'm sure there are 5 or 6 more...

    The big difference is in the U.S., we measure the grooves, in metric they measure the lands. So a U.S. .30 cal bullet is .308, in most of the world it is .311.
    Edit:Many 7.35 are classed as .30, I did not include them...

    "7.5X55" Swiss also uses a .308 bullet. Makes reloading easier for us Swiss Rifle owners......

    depends on the context.

    30 cal is a caliber it refers to a bullet with a diameter of .308" there are more 30 caliber cartridges out there then just about any other.

    7.62X38R (Nagant revolver) actually uses a .32 caliber bullet. At least our handloads do. The .308 bullet won't be very accurate, being too loose in the bore.

    Yep. The Russian Tokarev was about the same- I think 1 grain lighter bullet. Have friend that brought a Chinese Tok home from RVN (also brought a Chinses Tok bullet home with him, hard way) Got him 2 boxes of the 7.63 Mauser ammo, made his day.
