Well, the first one is roughly the caliber, as in the case of the 222 Remington (which fires a .224" bullet) or the 444 Marlin (which fires a .429" bullet). Wait, that is just more confusing. But it gets easier as you move into pistol cartridges: for example, there is the venerable 38-40 (which is a .40" bullet over 38 grains of powder) and the 44-40 (which is a .427" bullet over 40 grains of powder). Okay. those may not be the best example. Hmm, how about 38 Special, which fires a .357" bullet . . .no, that isn't any good either.
Sounds to me like the OP is trying to start a fight!
