The CCI #10 Percussion Cap (Part #0309 or #309) is a specialized, high-reliability primer designed primarily for cap-and-ball revolvers and smaller percussion firearms, exclusively stocked at Glenwood Springs Outdoors for black powder enthusiasts. These caps feature a non-corrosive, non-mercuric priming compound that delivers clean, consistent ignition without the heavy fouling associated with older mercuric formulas—making post-shoot cleanup easier and extending the time between thorough cleanings.

Assembled in soft, ribbed copper cups for a secure grip, the #10 caps have a longer skirt and slightly smaller internal diameter compared to #11 caps, providing a tighter, more stable fit on the tapered nipples commonly found on imported or traditional revolvers (such as replicas of Colt, Remington, or other period pistols). This extended skirt increases surface contact, reducing the likelihood of caps slipping off during loading, rapid fire, or in humid conditions—critical for reliable performance in single-action revolvers or other percussion pistols.

Sold in convenient 100-count tins (often available in bulk 1000-count boxes of 10 tins), these caps offer excellent value for cowboy action shooters, historical re-enactors, or hunters using black powder substitutes like Pyrodex. The modern initiator mix ensures dependable flash and energy for consistent ignition across various loads, promoting smoother operation and fewer misfires when properly seated.

Black powder shooters favor the CCI #10 for its snug fit on revolver nipples, where #11 caps might feel looser, and its clean-burning properties that minimize residue buildup in chambers—ideal for extended shooting sessions or events requiring period authenticity with modern reliability. Always match caps to your firearm's nipple size (consult your revolver manual or test fit), and follow standard black powder safety practices, including eye protection and proper loading techniques.

Whether you're recreating Civil War-era revolver drills, competing in cowboy action matches, or enjoying casual target shooting with a classic cap-and-ball pistol, the CCI #10 provides the precise, dependable spark needed for flawless performance.
