Okay, I just learned something over on the shot gun board
I always wondered about what gauge numbers meant, but my question here is: what is the bullet diameter of the 45ACP? I ask this, because a .410 will shoot 45LC if I am correct. So, is the .45 really a measure of the case diameter like the 38 vs the 357?
sm said:We used to explain the "gauges" to new folks - being the # of lead balls of bore diamenter it took to equal 1 lb. The .410 explained as caliber , even so .410 equates to 36 ga.
