Caliber refers to diameter of the hole bored into the barrel of the firearm and the diameter of a bullet. Calibers are typically measured in millimeters, hundredths of an inch or thousandths of an inch but may not be exact measurements.
For example, a .357 Magnum and a .38 Special are both considered 38 caliber even though the bullet diameter is actually 357 thousands of an inch. Each firearm is rated to fire one or more specific calibers.
Most firearms have the caliber for rifles and handguns or gauge for shotguns clearly marked on the barrel or side of the receiver.
Example calibers: .22, .380, 9mm, .45, 10mm, .38, .357, 5.56/.223
Not to be confused with a bullet, a cartridge is a single round of ammunition made up of the the entire casing, primer, projectile and powder.
