DESCRIPTION |
||
|
his cartridge is designed for use against personnel and unarmored targets using .338 Magnum rounds at a range of 1200 meters. |
||
|
The main parts of the cartridge are: |

|
Projectile (bullet): |
At the top, you can see the streamlined shape of the bullet. Some designs feature a special core, such as a lead or tungsten carbide core, encased in a metal casing. |
|
|
Propellant (gunpowder): |
The dark, granular material that fills the brass casing is the propellant. When ignited, it burns rapidly, producing high-pressure gases that propel the bullet down the barrel. |
|
|

The outer brass container that holds all the components together. |
|
|
Prime: |
Located at the bottom center of the casing, this small primer contains a chemically sensitive compound that explodes when struck by the firing pin, igniting the propellant. |
