Primer (firearm)

thingiverse

Key components of modern munitions are explosive primers, also known as priming caps, which ignite a combustible propellant to propel a projectile out of its firing chamber at high speeds. The function and operation of explosive primers are integral to the entire process of artillery warfare. Typically consisting of a primary explosive such as lead styphnate, red mercuric oxide, or chlorate salts, explosive primers have undergone extensive research to develop various improvements. In contrast, cartridge primer systems consist of small metal cups containing primary explosives that generate sparks at detonation. A variety of these systems exist and their compatibility can significantly influence a firearm's reliability and firing precision. Firearm enthusiasts typically appreciate the reliable function of quality priming components which facilitate a precise match between ignition sources in hand-held weapons such as shotguns or hunting rifles.
