What is the Case in a cartridge?

• A. The primer
• B. The powder charge
• C. The metal or plastic container that holds all parts of a round of ammunition: primer, powder charge and bullet
• D. The bullet

Answer: (C)

The Case is the metal or plastic container that holds all parts of a cartridge—the primer in the base, the powder charge inside, and the bullet seated at the mouth. It provides the shape and strength needed to fit the firearm’s chamber and to contain the pressure from the powder when it ignites. After firing, the case expands to seal the chamber and is ejected. This is what distinguishes the case from the other components—the primer, the powder, and the bullet.
