CCI #11 Percussion Caps (100/50)

CCI #11 Percussion caps are the dependable ignition source black powder shooters trust, packaged here with 100 caps per box. If you shoot a caplock muzzleloader or a percussion revolver, the cap is the one component where reliability is absolutely non negotiable. A cap that fails to fire turns a hunt or a range session into an exercise in frustration.

CCI has built its reputation on priming products that go off when the hammer falls. That reputation is the entire reason this small copper cup sells by the case.

Where CCI #11 Percussion Caps Fit in the Black Powder World

The number 11 size is among the most common percussion cap sizes ever produced, used across a wide range of traditional rifles, pistols, and cap and ball revolvers. If you own one caplock firearm, there is a strong chance it was designed around this size. That popularity is what makes the number 11 the default choice on most black powder benches.

These caps suit muzzleloader hunters heading into primitive weapons season, historical shooters and reenactors who want period correct function, and cowboy action competitors running percussion revolvers on the clock. That said, cap fitment varies between makers and eras, so always confirm the correct cap size for your specific firearm before ordering a large quantity.

Key Features

• One hundred caps per box, priced so a spare tin in the possibles bag is easy to justify
• Number 11 sizing, the most widely specified percussion cap size in traditional shooting
• Consistent priming compound from CCI for positive ignition session after session
• Works across sidelock rifles, percussion pistols, and cap and ball revolvers
• Copper cup construction that splits cleanly and clears the nipple after firing
• Long shelf life when stored dry, which makes buying ahead of the season smart

Specifications and What They Change on the Range

The spec sheet lists size number 11, quantity 100 per box, and CCI as the manufacturer. Those are the only three numbers that matter here, and each of them has a practical consequence at the bench.

Size determines whether the cap seats with a light press and stays there. Too loose and it drops off during the draw or under recoil from a neighboring chamber, too tight and it deforms and gives an uneven strike. Number 11 hits the sweet spot on the majority of nipples produced over the last century and a half.

With 100 caps in the box, you are set for multiple range sessions or a full season of hunting preparation. Load development with a new powder charge alone can eat thirty or forty caps in an afternoon. Buying in quantity keeps you shooting instead of counting.

Practical Use, Storage, and Compatibility

Use a capper rather than bare fingers when you can. It seats the cap square, protects your fingertips near a revolver cylinder, and speeds up reloading dramatically in cold weather. Press until the cap is fully home on the nipple cone, then wipe the hammer face clean of fragments before the next string. CCI #11 Percussion caps seat with a light, positive push when the fit is correct.

Store the box in a cool, dry place well away from solvents. Priming compound tolerates age remarkably well but not moisture, so a sealed container inside your range bag is the right approach. Pick the nipple clear between sessions so fouling never blocks the flash channel.

For muzzleloader hunters, historical shooters, and cowboy action competitors alike, quality percussion caps are cheap insurance. Add a capper, a nipple pick, and a proper shooting pouch from our Apparel and Gear collection and you have a complete kit rather than a pile of parts.

Keep one tin working and one in reserve so a lost cap never ends a hunt. CCI has earned its place in the priming world, and a box of CCI #11 Percussion caps is the least expensive way to make sure your old gun speaks every time you ask it to. Ships direct to your door, no FFL required.
