Abstract : The patent relates to a percussion primer for small caliber ammunition in which the pellet loading can be accomplished by disc punching machines to increase primer production rates. A thin sheet of plastic material is seated in the base portion of the primer cup and has an upper surface coated with an abrasive material, preferably antimony sulfide. A plastic disc of igniter material overlies the abrasive material, and a plastic disc of high energy combustible material overlies the igniter disc. A protective foil overlies the combustible disc, and an anvil is seated in the cup and pressed against the foil.
