firearm ammunition

Firearm ammunition consists of four main components: a cartridge case, a primer, gunpowder, and a projectile (bullet). When the trigger is pulled, the firing pin strikes the primer, igniting the gunpowder. The explosion creates high-pressure gases that propel the bullet forward through the barrel. The cartridge case holds everything together and is ejected after firing for reloading. Ammunition types vary by caliber, design, and intended use, influencing factors like accuracy, range, and stopping power. Proper selection and handling of ammunition are essential for safety and effective firearm operation.
