Shell casing

Shell casing refers to the metal container that holds a cartridge’s ammunition together. It houses the primer, gunpowder, and bullet. When the firearm is fired, the primer ignites the gunpowder, creating gas that propels the bullet forward. The casing then ejects from the firearm, often automatically, so a new round can be loaded. Casings are usually made of brass, steel, or aluminum, and they can be collected and reused or recycled. In essence, the shell casing is an essential part of ammunition that facilitates firing and provides a reusable container for the shot.
