Re: Can you explain the diameter measurements used in bullets, wire and nails?
What they don't tell you is that the bullet info is only good for rifles and pistols. Shotguns have their own system. (The number, or gauge of a shotgun is the number of lead balls the size of the barrel it takes to equal a pound. So a 12-gauge is larger than a 20-gauge.) And some rifles have odd sizes and numbers. (I know of an 8 mm magnum.)
This site has only basic info, if you want more, try their links or do an Internet search.
