gauge, tells you how big the bore is of the shotgun.....
And the way you can tell the bore size is, a 12-gauge shotgun, 1 pound of lead will make 12 balls the diameter of the bore. A 20-gauge shotgun, 1 pound of lead will make 20 balls the diameter of the bore. 410 shotgun is the exception, it is like a rifle or pistol, the bore is .410"
