CCI Percussion Caps #11 – Reliable Ignition for Traditional Black Powder Firearms
For shooters who enjoy traditional black powder firearms, dependable ignition components are essential. CCI Percussion Caps #11 are widely used by muzzleloader enthusiasts and black powder shooters because they deliver consistent ignition and dependable performance.
These percussion caps are designed for firearms that use #11 cap ignition systems, including many traditional muzzleloading rifles, pistols, and cap-and-ball revolvers. When struck by the firearm’s hammer, the cap detonates and sends a spark through the nipple, igniting the black powder charge.
If you’re looking to buy CCI Percussion Caps #11, they remain one of the most trusted ignition components for black powder shooting and historical firearm reproductions.

What Are CCI Percussion Caps #11?
CCI #11 percussion caps are small metal caps containing a priming compound used to ignite black powder in percussion-cap firearms.
When the hammer strikes the cap:
-
The priming compound detonates
-
A flame travels through the nipple
-
The black powder charge ignites
This ignition system was widely used in firearms from the 19th century and is still used today in many reproduction and traditional muzzleloaders.
CCI manufactures percussion caps using non-corrosive and non-mercuric priming compounds, helping reduce corrosion and improve firearm longevity.

Why Black Powder Shooters Choose CCI #11 Percussion Caps
1. General-Purpose Ignition for Most Black Powder Firearms
The CCI #11 percussion cap is designed as a general-purpose cap suitable for many rifles, pistols, and revolvers that use #11 nipples.
Because of their versatility, they are commonly used for:
-
Traditional muzzleloading rifles
-
Cap-and-ball revolvers
-
Single-shot black powder pistols
This makes them one of the most widely used percussion caps among black powder shooters.

2. Reliable Ignition Performance
Reliable ignition is essential when shooting black powder firearms. Poor ignition can cause:
-
Misfires
-
Delayed firing
-
Inconsistent shot performance
CCI percussion caps are designed to provide consistent sensitivity and dependable detonation, helping ensure that the powder charge ignites properly when the hammer strikes the cap.
3. Non-Corrosive Primer Compounds
Traditional percussion caps used corrosive compounds that could damage firearm components if not cleaned properly.
CCI caps use modern non-corrosive and non-mercuric priming compounds, which help reduce corrosion and simplify firearm maintenance.
This means:
-
Less corrosion risk
-
Easier cleaning
-
Improved firearm longevity
4. Copper Construction for Reliable Fit
CCI percussion caps are assembled using soft ribbed copper cups, which help ensure they seat properly on the firearm’s nipple.
This design provides:
-
Secure fit on the nipple
-
Reliable detonation when struck
-
Consistent performance during shooting
Proper cap fit is important because loose caps can cause misfires or inconsistent ignition.
