Percussion caps, those small but mighty detonators, played a crucial role in the history of firearms. While many variations exist, the No. 11 percussion cap holds a special place, particularly among enthusiasts of antique firearms. This article delves into the specifics of No. 11 percussion caps, exploring their history, common uses, and current availability.
The History of Percussion Caps: A Brief Overview
Before the widespread adoption of metallic cartridges, percussion caps provided the reliable ignition needed for black powder firearms. These small copper or brass cups contained a highly sensitive explosive mixture, typically a blend of mercury fulminate and other compounds. When struck by the hammer of a firearm, the cap detonated, igniting the main charge of black powder and propelling the projectile. The development of percussion ignition represented a significant advancement over earlier flintlock mechanisms, offering increased reliability and a faster rate of fire.
Understanding No. 11 Percussion Caps: Size and Specificity
While the term "No. 11" might seem arbitrary, it refers to a specific size and potentially a manufacturer's designation. Unlike modern cartridges with standardized dimensions, percussion cap sizes varied somewhat across manufacturers and historical periods. The "No. 11" likely represents a common size prevalent during a particular era or among specific firearm manufacturers. Precise dimensions are difficult to standardize due to historical variations, but collectors and enthusiasts often refer to this size for certain types of antique firearms. Further research into specific firearm manuals or historical records can help clarify the exact dimensions for a given firearm.
