CCI Percussion Caps 11 available at SUPREME GUNSHOP. We made the muzzleloading world a lot brighter in 1975 when we introduced our #11 percussion caps. Why? They were non-mercuric, non-corrosive, and darned reliable. We’ve now expanded the line to four popular products. In addition to the #11, there’s the #11M with more power to light off replica black powders. For revolvers with smaller nipples, there’s our #10 cap. And for original and replica muskets and rifles that require large, winged caps, we have the Four Wing Musket Caps.
When using any percussion caps for reenactment 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.
We recommend a minimum internal diameter of 0.050 inches for nipples used without powder charges and bullets. Thoroughly clean nipples and the flame path during firing sessions. Always wear approved shooting glasses when firing any muzzleloading firearm.
