brass casing
Bullet's metal sleeve
A brass casing is the cylindrical metal shell that holds a bullet, propellant, and primer together as a single cartridge.
After firing, the casing is ejected from the gun.
Brass is preferred for its durability and ability to expand and seal the chamber during firing.
Spent casings litter shooting ranges and crime scenes: Police recovered three brass casings near the body.
