#11 Percussion Caps
Percussion caps are an important component used in firearms to ignite the propellant charge and fire the projectile. They are small metal caps containing a volatile explosive compound that is struck by the firearm’s hammer or firing pin, creating a spark that ignites the main powder charge.
CCI (Cascade Cartridge Inc.) is a well-known manufacturer of ammunition components, including percussion caps. Over time, CCI has continuously tested and improved its primers to enhance their performance. The latest CCI primers are designed to be more sensitive, making them easier to ignite. They have also been optimized for easier seating in the firearm’s nipple or primer pocket. This is particularly important when using progressive or automated loading equipment, where smooth and efficient primer seating is essential.
One notable application of percussion caps is for imported revolvers that feature smaller nipples. In such cases, specific percussion caps, such as the #10 caps, are used. These caps are specially designed to fit the smaller nipple size found in these imported revolvers.
It is worth mentioning that modern percussion caps, including those produced by CCI, utilize non-corrosive and non-mercuric initiator mixes. This ensures a clean burn during ignition, contributing to improved safety and reliability in firearms operations.
Overall, percussion caps play a crucial role in firearm ignition systems, and advancements in their design, such as those made by CCI, have resulted in more efficient and reliable ammunition components for shooters.
