The CCI #11 Percussion Cap (Part #311) is a trusted, industry-standard primer for muzzleloading firearms, exclusively available at Glenwood Springs Outdoors to deliver reliable, consistent ignition for black powder shooters. Introduced by CCI in 1975, these caps revolutionized muzzleloading with their modern non-corrosive, non-mercuric priming compound—eliminating the fouling and residue issues of older mercuric formulas while providing clean-burning performance that requires less aggressive cleaning after use.

Assembled in soft, ribbed copper cups just like the originals, the #11 caps are precisely matched to standard nipple dimensions on most percussion rifles, shotguns, revolvers, and pistols. This ensures a secure, snug fit that minimizes misfires and promotes dependable ignition for both traditional black powder and popular substitutes like Pyrodex or Triple Seven. The ribbed design enhances grip on the nipple, reducing the chance of caps falling off during loading or in wet conditions.

Available in convenient 100-count tins (often sold in bulk boxes of 1000 as 10 tins), these caps offer excellent value for hunters, target shooters, and historical re-enactors. Their reliable flash and controlled energy make them ideal for cap-and-ball revolvers, traditional sidelock rifles, and modern in-line muzzleloaders where consistent performance is key to accuracy and safety. Shooters praise the #11 for its sensitivity, ease of seating, and low failure rate across various weather conditions and load types.

Whether you're pursuing big game with a classic percussion rifle, competing in traditional black powder events, or enjoying casual plinking with a reproduction revolver, the CCI #11 provides the dependable spark needed for smooth, trouble-free operation. Pair them with proper safety practices—always wear eye protection and follow black powder loading guidelines—for optimal results.
