Primers - PERSONAL COLLECTION ONLY

Primers have the most important job in the cartridge “ go bang ”effect. The primer converts mechanical energy into a small fire that ignites the powder charge in the cartridge.
There are four primer sizes for common centerfire cartridges: small pistol, large pistol, small rifle, and large rifle.
Small rifle and small pistol primers look the same on the outside, but do not confuse the two when using them!
