The diameter of a bullet is measured in either decimals (of an inch) or millimeters. Either measurement refers to the caliber of a bullet.

Cartridge
A single round of ammunition. The brass casing that holds the powder and bullet and includes a primer. Once a cartridge is fired it is "empty" or "fired." When it still contains the powder and is fitted with a bullet and primer it is a "loaded" cartridge. The neck is the opening where the bullet goes in. The base is the bottom end of the cartridge.

Centerfire Rifles
These rifles are designed to take cartridges that have a removable primer in the center of the base of the cartridge.

Chamber
The place where a loaded cartridge is inserted into the back end of a barrel. The shape of the chamber matches the shape of the cartridge.

Rimfire Rifle
These are rifles designed to take cartridges that have a built-in primer system, around the edge of the base of the cartridge. To fire the cartridge, the firing pin strikes the edge of the cartridge base. Most rimfire rifles shoot 22 caliber cartridges. The cartridge is often referred to as 22 caliber rimfire."
