Are you trying to figure what are the basic parts of ammunition and what each piece of it does? Do you want a short guide to understanding how ammunition works? Then you’ve found the right place.

Here, we’ll cover each part of ammunition for the average gun. Whether you’re shopping for a new firearm, or are curious about how it works, read on for the important ammunition basics.


The primer is one of the most basic parts of ammunition. It’s located at the base of the cartridge and is typically filled with a small explosive charge. It also helps create pressure for firing the bullet out of the barrel of the gun.

Without a functioning primer, the other ammunition components would be completely useless. It must be strong enough to contain the blast created by the gunpowder inside the cartridge.

Generally, these are specially made with lead styphnate or barium nitrate for greater reliability. Primers come in all sizes and shapes, depending on the gun caliber and type of ammunition.


The powder is one of the basic parts of ammunition. It is an important component that is responsible for creating the pressure required for the bullet to be propelled out of the gun with enough force to cause damage.

The powder works by expanding rapidly away from the inner walls of the cartridge when it is ignited. This rapid expansion creates hot gas and pressure, which is then channeled out of the barrel and used to propel the bullet.

It typically consists of nitrocellulose, nitroglycerin, and sometimes other powdered metals to create the desired pressure. 

Shell Casings

Shell casings are the outer part of a cartridge of ammunition and are most commonly made of brass. The casing is specially designed to contain all the components of a cartridge together while allowing for the pressure generated from the burning propellant within to effectively eject the projectile.

The sides are rigid enough to prevent deformation or breakage yet flexible enough to allow for slight expansion during ignition while keeping the same outer diameter for consistent seating. 


Ammunition is a critical component of long rifle ammo and many other firearms. And one of the basic parts of ammunition is the bullet. It is the projectile that exits the firearm after the trigger is pulled.

It is usually a metal cylindrical tube with a pointed or rounded tip. These are propelled out of the firearm’s barrel by gunpowder, forming a force of rapidly expanding gas. The speed and distance traveled by the bullet are determined by the gunpowder and the grooves cut into the inside of the barrel.

Bullets are a key component of most firearms, and understanding how they work is an important part of being a responsible gun owner.
