.308 is simply that,.308/1000'ths of an inch in diameter,but what you might not know is that handfulls of different calibers are also .308/1000ths in diameter but use different names to not confuse people,like 30-30 is actually .308,.300 savage is .308,30-06 is .308,300 win mag is .308,and tons more.
