Comparing Caliber to Gauge
In comparison to caliber of rifled arms, it will be observed there is a marked difference; in this table, as the size of the gauge increases, the numerals designating the diameter of it decreases. Thus, the size of the hole in the barrel of a 25 gauge smooth bore is .571, while for 50 gauge smooth bore, it is only .453. For a rifle barrel of exactly .25 caliber, the bore should be .250; for a .50 caliber it would be 12 inch or .500. The caliber or gauge of the modern rifled arm, if correct, is designated decimally by hundredths. Thus, .32 caliber should be 32100, .40 caliber. 40100, etc., though few of them are really what they are called.
The approximate weight of these are as follows: 10 ga. 630 grs., 12 ga. 540 grs., 14 ga. 465 grs., .16 ga. 390 grs., 20 ga. 300 grs.
While we do not recommend round ball for choked bore shotguns, they are used by some shooters successfully; for 10 ga. choked bore use 12 ga. ball, for 12 ga. choked bore use the 14 ga. ball, and so on.
