The **primer** is the ignition system of the shell. This small, self-contained component sits at the base of the casing and contains a sensitive explosive compound. When struck by the firing pin of the rifle, the primer detonates, igniting the propellant (powder) inside the casing. There are different types of primers, with Boxer primers being common in thirty ought six ammunition.

The **propellant** (powder) is the heart of the shell’s power. This slow-burning explosive, typically made of nitrocellulose or a combination of nitrocellulose and other compounds, burns rapidly when ignited by the primer, generating expanding gases that propel the bullet down the barrel. Different types and amounts of powder are used to achieve various velocities and performance characteristics. The correct powder selection is crucial for achieving optimal accuracy and safely operating the firearm.

Various Uses of 30-06 Shells
