I always thought it was for "ball bearing"

Not sure, but I think the sizing of shot started in Britain.

There are quite a few shot sizes that have letter designations, B, BB, T, TT, and others, IIRC.

I've got a book at home with some information on it.

Well, I know as a kid that it stood for BUSTED BOTTLES.

BB A term with two distinct and separate meanings, the most common being the size of air rifle barrels or air rifle spherical steel shot - .175" in diameter. So widely used in this respect that 'BB gun' has become a generic term for all types of spring- and air-operated guns which use this type and size ammunition.

In reference to shotshells, a specific size of lead shot - .181" in diameter. Contrary to popular belief, BB shot size is not identical to BB ammunition size.

Hope this helps!
