    I know this is a dumb question, but here goes: I have seen references to both 30-06 and 7.62mm NATO as being .308. Yet 7.62mm equates to exactly .300 inch or 30 caliber. Is the .008 allowance for a snug fit in the 30 caliber barrel? If not, why is 7.62mm NATO also referred to as a .308? Thanks.
