Shotgun shells are generally measured by what?

Caliber
Length
Gauge
Weight

The correct answer is: Gauge

Shotgun shells are generally measured by gauge, which is a unit of measurement for the internal diameter of the gun barrel. Caliber refers to the diameter of the bullet, not the shell itself. Length and weight can vary depending on the type of shotgun and ammunition being used, so they are not universal measurements for shotgun shells. Therefore, gauge is the most accurate and common way to measure shotgun shells.
