Frequently Asked Questions

Why should you never pinch percussion caps for cap-and-ball revolvers?

Pinching percussion caps distorts their shape, creating gaps on the sides of the nipple. These gaps can allow flame to enter, leading to a dangerous chain fire where multiple chambers detonate unexpectedly. It's safer to use caps that fit correctly.

What are the risks associated with pinching percussion caps?

The primary risk of pinching percussion caps is the creation of gaps around the nipple. When the gun is fired, these gaps can allow hot gases and flame to escape, potentially igniting adjacent powder charges and causing a chain fire, which is extremely dangerous.

What are the recommended brands and types of percussion caps for cap-and-ball revolvers?

For Pietta and similar cap-and-ball revolvers, Remington No. 10 caps are often the best fit. If those are unavailable, CCI No. 11 caps (including Magnum versions) are a good alternative, offering the same internal diameter.

How can you ensure percussion caps stay securely on the nipples of a cap-and-ball revolver?

The best approach is to use percussion caps that fit snugly without being forced. If using CCI No. 11 caps, which are slightly shorter, it's recommended to check them between shots and gently push them back onto the nipple if they have backed out due to recoil.
