What's bigger than a 12 gauge?
Consequently, what is bigger 12 gauge or 20?
A 20 gauge is smaller than a 12 gauge, so more lead balls in the diameter of the gore, would be required to add up to one pound. Common gauges: 10 gauge = 10 balls; 12 gauge = 12; 16 gauge = 16; 20 gauge = 20.
One may also ask, which is bigger 12 gauge or 410?
In short, the smaller the gauge of a shotgun, the larger the bore diameter. This is why a 10 gauge shotgun has a larger diameter than a 12 gauge shotgun, which has a larger diameter than a 20 gauge shotgun, etc. 410 of an inch diameter) as opposed to a gauge number.
Gauge is determined by the number of lead balls equal in diameter to the barrel that it would take to weigh one pound. In a 12 gauge, which has a barrel diameter of . Likewise, for a 16 gauge, which has a barrel diameter of . 662 inches, it would take 16 lead balls to equal a pound.
