Your One-Stop Shop for Black Powder Muzzleloader Accessories

There has been an increased demand for modern centerfire cartridges and primers, leading to a shortage of percussion caps. Ammunition manufacturers have been working diligently to meet the high demand for centerfire ammunition, causing percussion caps to receive less production time due to their smaller share in the market. As a result, shooters and enthusiasts using muzzleloading firearms or participating in historical reenactments might experience challenges in finding available percussion caps during this period.

Yes, you can make your own dummy percussion caps, and it is generally safer than attempting to make live ones. Dummy percussion caps are non-functional replicas that do not contain explosive material and are commonly used for training, demonstrations, or historical reenactments. These dummy caps can be used to simulate the loading and firing of a percussion-based firearm without the risk associated with live ammunition.

No. 10 percussion caps are commonly used for small-caliber muzzleloading firearms. They are specifically designed to fit on the nipple of percussion cap muzzleloaders and are used to ignite the black powder charge inside the firearm's barrel.

These caps are slightly smaller than the more widely known No. 11 percussion caps. They are typically used for smaller caliber firearms.

Historically, No. 11 percussion caps were commonly used in various firearms, including pistols, revolvers, muskets, and rifles, during the mid-19th century and beyond. Today, they are still used in black powder shooting, historical reenactments, and for those who enjoy traditional shooting sports with muzzleloading firearms.

During the Civil War, musket percussion caps, played a pivotal role in firearms technology. These caps served as the ignition source for gunpowder, replacing earlier flintlock systems. Positioned on top of a percussion nipple, a small tube extending from the breech of the firearm, the musket cap was struck by a hammer when the trigger was pulled, igniting the gunpowder and firing the weapon. This innovation significantly improved reliability and speed compared to previous ignition methods. Musket caps found extensive use in Civil War-era firearms, including muskets, rifles, and pistols, contributing to the evolution of modern weaponry.

Historically, percussion caps were manufactured through a careful process involving several steps. Thin discs of brass or copper were cut into the desired size and shape to form the base of the percussion cap. These discs were then stamped or drawn into small cups. The cups were filled with the priming compound, fulminate of mercury. Once the cups were filled with the priming compound, they were sealed with a thin layer of varnish or lacquer. The sealed percussion caps were left to dry and harden.
