Definition

Caliber refers to the internal diameter of a firearm’s barrel, measured in millimeters or inches. It is commonly used to describe rifles and handguns, but in shotguns, the term gauge is more accurate and widely applied.

Further Explanations

In general shooting sports, caliber tells you the bullet size a firearm can shoot. For example, a 9 mm pistol or a .308 rifle. However, clay shooting primarily uses shotguns, which are measured in gauge rather than caliber.

Key differences between caliber and gauge:

• Caliber: Used for rifles and pistols, measures bore diameter directly

• Gauge: Used for shotguns, based on the number of lead balls (of bore size) needed to weigh one pound

• Common shotgun gauge: 12 gauge is the standard for clay shooting, though 20 gauge is also popular for lighter recoil
  
  

Understanding the distinction helps new shooters avoid confusion when discussing equipment.
