It is an indication of the diameter of the inside of the barrel. The larger the number, the smaller the diameter. It works like this: the number is how many balls that size make up one pound of lead, so a 20 gauge barrel is the diameter of a ball, 20 of which would make up one pound. 12 gauge is the size ball that 12 balls would make one pound. This is correct except for .410, which is the actual bore size of 41/100".
Yes, 20 gauge is the second most common gauge for shotguns in the last few decades.
Gauge
I can say that Browning started having shotguns made in 16 gauge in the year 1909.Winchester started having the model 12 shotguns made in 16 gauge in the year 1914.so I would surmise that the time frame of 1909-1915 would be the correct time frame for the introduction of the 16 gauge shotguns.
Ithaca made 10 gauge shotguns.
12 has a bigger bore.
Shotguns are described by gauge, not caliber. It should be marked on the barrels as to which is the correct ammuntion and gauge. Shotguns are described by gauge, not caliber. It should be marked on the barrels as to which is the correct ammuntion and gauge.
