CCI® #10 Percussion Caps provide the reliable, consistent ignition blackpowder shooters need. They feature non-corrosive, non-mercuric priming compounds with soft, ribbed copper cups, and they are available in a variety of styles.

CCI® Percussion Caps are fabricated from a non-corrosive, non-mercuric compound mix and assembled in individual, ribbed, copper caps for use in black powder revolvers having smaller nipples. These ribbed caps match standard #10 nipple sizes and provide both clean burning and extremely reliable ignition.

These percussion caps are continuously being tested and improved. As a result, today's Percussion Caps are more sensitive, easier to seat and more compatible with progressive and automated loading equipment than ever before.

When using any percussion caps for re-enactment or demonstration shooting without a powder charge or bullet, only use nipples with a large internal diameter. Standard nipples intended for normal loads can clog when fired repeatedly without a powder charge, potentially causing the cap to fragment. CCI recommend a minimum internal diameter of 0.050 inch for nipples used without powder charges and bullets. Thoroughly clean nipples and the flame path during firing sessions.
