Which of the following are the primary components of a cartridge?

The primary components of a cartridge are the projectile, casing, primer, and propellant. Understanding these components is crucial for anyone involved in ammunition handling.

The projectile is the part that is expelled from the firearm and is responsible for delivering the intended force to a target. The casing is the container that holds all the other components together and is typically made from brass, steel, or aluminum. The primer is a small charge located at the base of the cartridge that ignites the propellant when struck by the firing pin. Finally, the propellant, often a type of gunpowder, is what generates the gas pressure needed to propel the projectile down the barrel when ignited.

Each of these elements plays a vital role in the functioning of a cartridge, making it essential knowledge for anyone certified in handling ammunition. Other options may mention components that are not part of a standard cartridge, or mix terms that pertain to different types of ammunition or firearms, which can lead to confusion in understanding the fundamental structure of a cartridge.
