Percussion Primer

A primer is a type of percussion instrument that is used to ignite or initiate the combustion of a propellant in firearms. It is typically a small metal or plastic cap that contains a small amount of explosive material. When struck by the firing pin of a firearm, the primer ignites, creating a small flame that travels through the ignition channel and ignites the main propellant charge, causing the bullet to be propelled out of the barrel. In addition to firearms, primers are also used in other applications such as fireworks, flares, and certain types of industrial equipment. They are designed to be highly reliable and consistent in their ignition properties, ensuring that the main propellant charge is ignited consistently and efficiently.
