The four main parts of a rifle cartridge are indeed the case, primer, powder, and bullet. Each of these components plays a critical role in the functioning of the cartridge:

- The case is the container that holds all the other parts and provides the structure necessary to contain the pressure generated when the powder ignites.

- The primer is a small explosive device that ignites the gunpowder when struck by the firing pin. It serves as the initial catalyst for firing the cartridge.

- The powder, typically gunpowder, is the propellant that burns and generates gas, creating pressure that forces the bullet down the barrel and out of the gun. This is essential for the actual propulsion of the bullet.

- The bullet is the projectile that is fired from the rifle's barrel when the cartridge is discharged.

Understanding these parts is fundamental for safe handling and operation of rifles, as each component interacts in a specific way to ensure reliable performance. Knowing the correct components helps hunters and shooters appreciate the mechanics behind their firearm and the ammunition they use.
