Gauge is defined as?

• A. The measurement of shotgun bores derived from the number of bore-sized lead balls per pound
• B. The diameter of the bore in inches
• C. The weight of the powder charge
• D. The number of pellets in a shell

Answer: (A)

Gauge measures shotgun bore size using a historical method: it’s the number of lead balls that would fit the bore and weigh one pound. In other words, the bore size is defined by how many of those lead balls would make up a pound. A smaller gauge number means a larger bore, and a larger gauge number means a smaller bore. For example, a 12-gauge bore would accommodate about twelve lead balls per pound, while a 20-gauge bore would use about twenty, indicating a smaller diameter. This concept helps determine which shells fit the firearm. It’s not the bore diameter in inches, not the powder charge weight, and not the number of pellets in a shell.
