AMMUNITION

Ammunition generally refers to the assembled components of complete cartridges or rounds i.e., a case or shell holding a primer, a charge of propellant (gunpowder) and a projectile (bullets in the case of handguns and rifles, multiple pellets or single slugs in shotguns). Sometimes called 'fixed
ammunition' to differentiate from components inserted separately in muzzleloaders.
