What Are CCI Percussion Caps #11 Magnum?
CCI #11 Magnum percussion caps are small ignition caps used in percussion-cap firearms. These firearms include traditional muzzleloaders and cap-and-ball revolvers that rely on percussion caps to ignite the powder charge.
A percussion cap fits onto a nipple on the firearm’s ignition system. When the hammer strikes the cap, it detonates and sends a spark through the nipple into the powder charge, igniting the black powder.
The magnum version of the #11 cap produces a stronger ignition flame compared to standard caps, which helps ensure reliable ignition of certain powders and powder substitutes.
Why Shooters Choose CCI #11 Magnum Percussion Caps
1. Hotter Ignition Flame
The key advantage of CCI #11 Magnum percussion caps is their stronger ignition power.
Magnum caps provide:
-
A hotter ignition spark
-
Better ignition of black powder substitutes
-
More reliable performance in difficult conditions
This extra ignition energy can be especially helpful when using powders such as Pyrodex or other black powder substitutes.
2. Reliable Ignition in Black Powder Firearms

CCI designed their percussion caps to ensure:
-
Consistent ignition
-
Reliable detonation when struck
-
Dependable performance in the field
These qualities make CCI percussion caps a popular choice among black powder shooters.

3. High-Quality Copper Construction
CCI percussion caps are manufactured using soft ribbed copper cups, which help ensure reliable detonation when struck by the firearm’s hammer.
The copper cup design provides:

Consistent ignition sensitivity
-
Secure fit on the firearm’s nipple
-
Reliable detonation with hammer impact
These features help maintain dependable performance across many shooting sessions.
4. Non-Corrosive Primer Compound

Benefits of this design include:
-
Reduced corrosion in the firearm
-
Easier cleaning after shooting
-
Improved long-term firearm reliability
This is especially important for black powder firearms, which already produce significant fouling during use.
