Percussion caps are an essential component of firing black powder revolvers, providing the spark needed to ignite the powder charge. Understanding percussion caps, their types, and proper usage is crucial for safe and reliable shooting. This comprehensive guide explores everything you need to know about percussion caps for black powder revolvers.
Understanding Percussion Caps
Percussion caps are small, metal cups containing a sensitive explosive mixture. When struck by the hammer of a firearm, the mixture detonates, producing a spark that ignites the black powder in the firearm's chamber. This process is vital for the reliable ignition of the main charge. The quality and reliability of your percussion caps directly impact the performance and safety of your black powder revolver.
Types of Percussion Caps
Several types of percussion caps exist, each with slight variations in design and performance:
-
Standard Percussion Caps: These are the most common type, typically made of copper or brass. They are widely available and suitable for most black powder revolvers.
-
#11 Percussion Caps: These are slightly larger than standard caps, offering potentially more consistent ignition, though this difference might be subtle in practice.
-
Rifle Caps: While often used interchangeably, rifle caps are sometimes designed with a slightly stronger charge for more reliable ignition in rifles, potentially offering more forceful ignition in revolvers, but not always necessary.
-
MagTech Percussion Caps: MagTech offers a variety of percussion caps known for their reliability and consistent ignition.
-
CCI Percussion Caps: CCI, a well-known brand in ammunition, also produces a line of percussion caps.
It's important to note that using the incorrect cap size can lead to misfires or even dangerous malfunctions. Always use the type and size of cap specifically recommended for your black powder revolver.
Choosing the Right Percussion Cap
Selecting the appropriate percussion cap depends on several factors:
-
Your Revolver's Specifications: Your revolver's manual will specify the recommended cap size. Using the wrong size can damage your firearm or lead to unsafe conditions.
-
Environmental Conditions: In cold or damp conditions, you may find that certain cap brands or types offer more reliable ignition. Experimentation may be necessary to find what works best in your specific environment.
-
Personal Preference: While performance differences are often subtle, some shooters prefer certain brands based on personal experience with reliability and consistency.

Using Percussion Caps Safely
Safe handling of percussion caps is paramount. Always follow these safety precautions:
-
Store caps in a cool, dry place: Avoid extreme temperatures and humidity.
-
Never handle caps near open flames or sparks: Percussion caps are extremely sensitive.
-
Use a cap crimper: Properly seating caps on nipples is essential. A cap crimper ensures consistent and reliable ignition. Improperly seated caps are a major cause of misfires.
-
Inspect your caps: Before loading your revolver, visually check your caps for any signs of damage or defects.
-
Handle caps carefully: Avoid dropping or jarring them.
-
Always wear eye protection: Even with proper handling, accidents can happen.
-
Understand your revolver: Familiarize yourself with its proper operation and safety procedures before handling live ammunition.
Troubleshooting Misfires
Misfires can be frustrating, but understanding the causes can help prevent them in the future. Common causes include:
- Improperly seated caps: Use a cap crimper for consistent seating.
- Damp or deteriorated caps: Store caps properly and inspect them before use.
- Dirty nipples: Clean nipples regularly with a nipple pick.
- Low-quality caps: Consider switching to a more reliable brand.
- Weak mainspring: The strength of the mainspring affects the force with which the hammer strikes the cap.
If you experience repeated misfires, consider consulting a qualified gunsmith.
Conclusion
Percussion caps are a critical part of safely and effectively operating black powder revolvers. Understanding their types, selecting the right ones for your firearm, and practicing safe handling procedures are essential for a positive shooting experience. Remember, safety should always be your top priority when handling black powder firearms and ammunition. Regular maintenance, proper storage, and using high-quality caps will contribute to reliable operation and enjoyable shooting.
