For small guns the case contains a percussion primer, usually a copper cap filled with a chlorate mixture and resting against an anvil. [2] The striker of the gun strikes the cap and fires the ...
CCI (Cascade Cartridge Inc.), based in Lewiston, Idaho, manufactures rimfire ammunition, centerfire handgun ammunition, and primers for reloaders and industrial ammunition production. CCI made the first mini-mag rimfire ammunition in 1963, and in 1975 developed the Stinger, a high velocity .22 Long Rifle product.

Percussion caps have been manufactured in various sizes to fit snugly over different sized nipples. Nipples for 4.5mm and 6mm percussion caps. The percussion cap, percussion primer, or caplock, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition.
