# Meaning Of Gauge And Barrel Of Gun?

•  2
Hi,

One of several meanings of gauge is:

1: The size of a shortgun barrel's inner diameter nominally expressed as the number of lead balls each just fitting that diameter required to make a pound.

or

2: The gauge or bore is determined by the number of solid spheres of a diameter equal to the inside diameter of the barrel that could be made from a pound of lead. (according to wikipedia)

For a 12-gauge shotgun: if a pound of lead (Pb) were melted down and formed into twelve identical lead spheres, the spheres would have a diameter equal to the diameter of the inside of the gun barrel.
Mister MicawberFor a 12-gauge shotgun: if a pound of lead (Pb) were melted down and formed into twelve identical lead spheres, the spheres would have a diameter equal to the diameter of the inside of the gun barrel.

So, MM, the gauge is also a reflection of the total volume of the barrel or the total load/charge, not only of the diameter?
