CCI Primers are continuously tested and improved. As a result today’s CCI primers are more sensitive. Easier to seat and more compatible with progressive and automated loading equipment than ever before.

They utilize modern non-corrosive and non-mercuric initiator mixes for the cleanest burn possible. Ideally, a proper fitting cap will contact the top of the cap, and fit snugly in place.

CCI® #10 Percussion Caps   made of a non-corrosive, non-mercuric compound mixture and  assembled in individual, ribbed copper caps for use in black powder revolvers with smaller nipples. These ribbed caps  designed to fit standard #10 nipple sizes and provide clean burning and extremely reliable ignition.
