CCI® Primers #11 Percussion Caps / Buy The #11 Percussion Caps Today/ Elite Primers

CCI® Primers #11 percussion caps are fabricated from a non-corrosive, non-mercuric compound mix and assembled in individual, ribbed, copper caps for standard revolvers,  rifles and muzzleloaders. These ribbed caps match standard #11 nipple sizes and provide both clean burning and extremely reliable ignition.

These Magnum 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. CCI’s™ Magnum #11 Percussion Caps are packed in traditional 100 count tins and can be ordered in 100 to 5000 count.

**Do not exceed the loads displayed in the loading guide. Never mix any two powders regardless of type, brand, or source. Never substitute any smokeless powder for Black Powder or any Black Powder substitute.

Are CCI percussion caps really non corrosive?

I am using new CCI 11 caps and they do claim to be non corrosive, are they really? I know some powders claim to be when actually they aren’t….

Blackpowder season opened here today and my plan is to snap a few caps on a clean barrel and then load normally with a mink oil patch and round ball. our season is 2 weeks so my rifle may be loaded until then or until I actually take a shot at something. I don’t want to have to unload and clean every day I hunt unless I get rained on. If I take a shot I will of course break down and clean my rifle properly. But if I only fire caps to and no powder then I shouldn’t have to clean or worry about my rifle rusting correct?



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″ 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.
