A complete round of artillery ammunition has four parts: the case, the primer, the powder, and the bullet.

Case

A cartridge casing houses all the other parts. The pistol or rifle case can be Brass, steel, or copper. Plastics are also used, but a thin layer of Brass covers the bottom.

The primer

The primer is located at the bottom of the cartridge. When the firing pin hits the primer, an explosion sets the gunpowder on fire. The eruption starts a fire that spreads through the shell and lights the powder.

Powder

Gunpowder, also called propellant, is a material inside the cartridge case that burns quickly. Both chemical explosives and black powder or smokeless powder can be used as Propellant. The propellant burns so quickly that it makes a gas that increases the pressure inside a cartridge.
