Actually, the first number represents the caliber and the second number represents the charge weight. So it is 38 caliber with 40 grains of black powder.
However the .38-40 has a bullet that is actually .410 in diameter. Confused yet?
Here is some reading on the .38-40
No I am not confused. Why Winchester named this cartridge this way is a mystery, or at least I have not found the reason. It should actually be a
.40-38. I think Winchester was confused. And actully, while we are nitpicking, the good old .44-40 isn't a 44 but a .427 and the .38 special is a .358 and the .32 S&W long is a .312. I collect cartidges and live by the book "Cartridges of the World". It is a great reference.
