PRODUCT OVERVIEW : #11 Percussion Caps


In the world of firearms and pyrotechnics, #11 percussion caps play a vital role. These small yet powerful ignition devices are essential components in various applications, from traditional muzzleloaders to modern sporting firearms. This article dives into the world of #11 percussion caps, exploring their history, types, functionality, advantages, common uses, and safety considerations. Whether you’re an avid shooter, a pyrotechnics enthusiast, or simply curious about this fascinating subject, this article will provide you with a comprehensive understanding of #11 percussion caps.

What are Percussion Caps?

Percussion caps are small metal caps containing a volatile compound that ignites upon impact. They are used as the primary ignition source for firearms, fireworks, and other applications that require controlled and reliable ignition. Percussion caps replaced the earlier flintlock ignition systems, offering improved reliability and ease of use.

History of Percussion Caps

The invention of percussion caps is attributed to Scottish clergyman Alexander John Forsyth, who patented his design in 1807. Forsyth’s percussion cap used a fulminate of mercury compound to create a reliable ignition source. The percussion cap quickly gained popularity due to its simplicity and efficiency, eventually leading to the widespread adoption of percussion-based firearms.

Types of Percussion Caps

There are various types of percussion caps available in the market, each designed for specific applications. The most common types include #10 percussion caps, #11 percussion caps, and musket caps. In this article, we’ll focus on the #11 percussion caps, which are widely used in modern firearms and pyrotechnics.

#10 Percussion Caps

#10 percussion caps are slightly smaller than #11 percussion caps and are primarily used in smaller firearms, such as pistols and revolvers. They provide a reliable ignition source for these compact weapons and are known for their consistent performance.

#11 Percussion Caps

#11 percussion caps are the most popular and widely used percussion caps. They have a standard size and are compatible with a vast range of firearms, including rifles, shotguns, and muskets. Their versatility and reliability make them a preferred choice among shooters and hunters.

Musket Caps

Musket caps are larger percussion caps specifically designed for muskets, which are long-barreled firearms used in historical reenactments and certain shooting disciplines. Musket caps offer enhanced ignition power suitable for these larger weapons.

How Percussion Caps Work

When a hammer strikes a percussion cap, the impact causes the fulminate of mercury compound inside the cap to detonate. This ignition produces a small flame, which then travels through a small vent or flash hole in the firearm’s breech. The flame ignites the main propellant charge, leading

CCI #11 Percussion Caps are continuously tested and improved. As a result today’s CCI primers are more sensitive, easier to seat and more compatible with progressive and automated loading equipment than ever before. They utilize modern non-corrosive and non-mercuric initiator mixes for the cleanest burn possible to the firing of the projectile or the ignition of pyrotechnic effects.

Advantages of Using Percussion Caps

Percussion caps offer several advantages over alternative ignition systems. Firstly, they provide a more reliable and consistent ignition source, ensuring consistent performance and accuracy in firearms. Unlike flintlock systems that rely on striking a piece of flint against steel, percussion caps eliminate the dependence on external sparks, making them less affected by adverse weather conditions.

Furthermore, percussion caps are relatively easy to handle and install, making them user-friendly for both experienced shooters and beginners. They provide a secure and efficient method of igniting the propellant charge, minimizing the risk of misfires and malfunctions.

Common Uses of #11 Percussion Caps


#11 percussion caps find widespread use in various firearms, ranging from rifles and shotguns to black powder pistols. They are a crucial component in traditional muzzleloaders and black powder firearms, as well as in modern replicas of historical firearms. The consistent ignition provided by #11 percussion caps ensures reliable firing and consistent accuracy.


Beyond firearms, #11 percussion caps have a role in the world of pyrotechnics. They are employed in fireworks and other pyrotechnic devices to initiate the combustion and subsequent release of vibrant colors, sparks, and other dazzling effects. The reliability and precision of #11 percussion caps make them a preferred choice for pyrotechnic professionals and enthusiasts alike.

Tips for Using #11 Percussion Caps

  1. Ensure proper alignment: When placing a #11 percussion cap on a firearm, make sure it is correctly aligned with the nipple or cone. Misalignment can hinder the ignition process.
