Which of the following are components of a cartridge?

A cartridge is a complete unit of ammunition used in firearms, and it consists of several critical components that work together to facilitate firing. The correct answer includes the case, powder, primer, and projectile.

The case serves as the housing that contains all other components and protects them from damage while also allowing for a secure fit in the firearm's chamber. The powder, often referred to as gunpowder, is the propellant that ignites and creates the gas needed to propel the projectile forward when fired. The primer is a small charge that ignites the powder when struck by the firing pin, initiating the firing process. Finally, the projectile, typically known as a bullet, is the actual object that is expelled from the barrel when the cartridge is fired.

Understanding these components is crucial for safe and effective firearm operation, as each part plays a vital role in ensuring the cartridge functions as intended.
