Percussion caps, specifically the No. 11 variety, hold a significant place in firearms history and continue to fascinate collectors and enthusiasts today. This guide delves into the specifics of No. 11 percussion caps, exploring their history, characteristics, usage, safety precautions, and where to find them.
Understanding Percussion Caps: A Brief History
Before the advent of metallic cartridges, percussion caps provided the crucial ignition for black powder firearms. These small, copper-based caps contain a sensitive explosive mixture that, when struck by the hammer, ignites the main charge of black powder, propelling the projectile. Different manufacturers produced caps with varying sizes and strengths, leading to a range of designations like the No. 11.
The Distinctive Features of No. 11 Percussion Caps
While the exact specifications might vary slightly between manufacturers and over time, No. 11 percussion caps generally share common characteristics. These include:
- Size and Dimensions: No. 11 caps typically feature a specific diameter and height, making them suitable for certain types of firearms. Precise measurements should be researched based on the specific firearm being used.
- Composition: Primarily composed of copper, they contain a small quantity of a sensitive explosive mixture, usually a blend of mercury fulminate and other compounds.
- Shape and Construction: They typically have a slightly concave base to sit firmly within the nipple of the firearm. The construction is robust enough to withstand handling and transportation, yet sensitive enough to detonate reliably.
Using No. 11 Percussion Caps Safely
Safety is paramount when handling any type of firearm, including those using percussion caps. Always prioritize safety procedures:
- Proper Storage: Store percussion caps in a cool, dry, and well-ventilated area away from direct sunlight and ignition sources. Keep them securely sealed in their original containers.
- Careful Handling: Avoid dropping or mishandling caps. Never tamper with the internal composition.
- Firearm Knowledge: Only use No. 11 percussion caps with firearms specifically designed for them. Consult relevant manuals and resources to ensure compatibility.
- Professional Guidance: If you are unfamiliar with black powder firearms, seek guidance from experienced users or professionals.
Sourcing No. 11 Percussion Caps: Where to Find Them
Finding No. 11 percussion caps can sometimes be challenging, as modern manufacturing focuses on more contemporary ammunition. However, some avenues exist:
- Specialized Dealers: Many dealers specializing in black powder firearms and related accessories stock percussion caps, including No. 11. Online searches can reveal several reputable vendors.
- Gun Shows: Gun shows often feature vendors selling a range of antique and modern ammunition, including percussion caps.
- Collectible Markets: Online auction sites and collectible firearm marketplaces might offer No. 11 caps, but exercise caution and thorough due diligence when purchasing from such sources.
Preservation and Collection of No. 11 Percussion Caps
For collectors, preserving the quality and historical significance of No. 11 percussion caps is crucial. Proper storage, as detailed above, is vital. Furthermore, documenting the caps' origin (if known) and condition can enhance their value and historical interest. Researching the manufacturers and the historical context of their usage adds another layer of appreciation for these intriguing artifacts.
