WebPrimer (firearm) In firearms and artillery, the primer (/ˈpraɪmər/) is the chemical and/or device responsible for initiating the propellant combustion that will push the projectiles out of the gun barrel. In early, black powder guns such as muzzleloaders, the primer was essentially the same chemical as the main propellant (albeit usually in ... WebA primer is the component of a handgun or rifle that provides the spark that ignites the gun powder. This causes combustion, which pushes the ammo out of the gun barrel. Some … WebFirearms examiners identify gun shot residue (GSR) by detecting primer residue particles. Most residue expelled from a gun consists of burned, unburned, or partially burned propellant which contains metal particulates such as lead, copper, brass, or nickel from the jacketing material.
