Description

For black powder enthusiasts and historical firearm aficionados, percussion caps are a critical component of the shooting experience. Among these, #10 percussion caps hold a special place due to their unique size and compatibility with specific firearms. Whether you’re a seasoned muzzleloader or a curious newcomer, here’s everything you need to know about #10 percussion caps.

What Are #10 Percussion Caps?

#10 percussion caps are small, copper or brass cups containing a tiny amount of shock-sensitive explosive (historically mercury fulminate, now often a substitute like potassium chlorate). Designed to fit nipples (cones) on black powder firearms, they provide the ignition spark needed to fire the main powder charge. The “#10” refers to their size, which is slightly smaller than the more common #11 caps.

Why #10 Caps Matter Precision Fit:

The #10 size is ideal for firearms with smaller nipples, such as certain revolvers (e.g., Pietta or Uberti replicas) or older rifles. A snug fit ensures reliable ignition and reduces the risk of caps falling off during handling. Historical Accuracy: Many Civil War-era revolvers and mid-19th-century muzzleloaders were designed for #10 caps. Using them in reproductions enhances authenticity for reenactors. Performance: Properly fitted caps minimize misfires and improve consistency, especially in competitive shooting or hunting scenarios.

Firearms That Use #10 Caps Revolvers:

Colt 1851 Navy, Remington 1858 New Army (some reproductions), and other cap-and-ball revolvers. Rifles/Pistols: Certain Kentucky-style rifles and derringers. Always check your firearm’s manual or consult a gunsmith to confirm nipple size.

#10 vs. #11 Caps: What’s the Difference? Size:

#10 caps have a slightly smaller diameter than #11s. Using the wrong size can lead to poor ignition (if too loose) or difficulty seating (if too tight). Availability: #11 caps are more widely produced, so #10s may require hunting at specialty stores or online retailers. Workarounds: In a pinch, some shooters pinch #11 caps to fit smaller nipples, but this isn’t ideal for reliability.

Tips for Using #10 Caps Safely Storage:

Keep caps in their original container, away from moisture, heat, and open flames. Handling: Avoid crushing or mishandling caps—they’re sensitive to impact. Clean Nipples: Residue buildup can prevent caps from seating properly. Use a nipple pick to clear debris.

Where to Find #10 Percussion Caps

While less common than #11s, #10 caps are still produced by brands like CCI, RWS, and Treasure Mountain. Check online at reload-pro.com
