______ is a term that describes the size of a rifle or handgun bore and the size of cartridges used with different bores.

• A. Gauge
• B. Caliber
• C. Shot charge
• D. Action

Answer: (B)

Caliber describes the size of the bore in a rifle or handgun and the corresponding cartridge diameter that fits that bore. It’s measured in inches or millimeters, like .308 caliber or 9 mm, linking the gun’s bore to the ammunition it’s designed to fire. For shotguns, the bore size is described by a different system called gauge, which can be confusing if mixed with rifles, since gauge uses a different method (how many lead balls of that bore fit in a pound). Shot charge is about the amount of shot in a shell, and action refers to the mechanism that loads and unloads cartridges. So caliber is the term that best describes both bore size and the cartridge size for rifles and handguns.
