no 11 percussion caps In 1975 introduced the #11 percussion caps to the muzzleloading market. Why? No mercury, no corrosives, and damned reliable. CCI presently offers four popular goods. The #11M has greater power to ignite up black powders than the #11. The #10 cap fits revolvers with smaller nipples. They also have Four Wing Musket Caps for authentic and replica muskets and rifles. Use only nipples with a large internal diameter when shooting without a powder charge or bullet. Normal nipples can clog when fired repeatedly without a powder charge, causing the cap to fragment. For nipples without powder charges or bullets, CCI recommends 0.050 inch internal diameter. During firing, clean the nipples and the flame path. Always use authorized muzzleloading shooting glasses.
no 11 percussion caps 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.
#10 caps are for some imported revolvers having smaller nipples
CCI No. 10 Caps ended up fitting my original Remington .44 perfectly. They also fit both of my Cimmaron Colt 1860s perfectly. So, I am very happy with this, since finding the right Cap makes a world of difference from Caps which are too loose or too tight.
