Frequently Asked Questions

What are the main powder options for cap and ball revolvers?

The primary options for cap and ball revolvers are traditional black powder, often called 'holy black,' and various powder substitutes. Common substitutes include Pyrodex and Triple Seven, which are often used when black powder is not readily available or for perceived ease of use.

Are powder substitutes for cap and ball revolvers less corrosive than black powder?

Contrary to a common misconception, powder substitutes like Pyrodex and Triple Seven are generally more corrosive and harder to clean than real black powder. While they can be cleaned with soapy water, they tend to gum up the firearm more than traditional black powder.

How should I load Pyrodex in a cap and ball revolver?

When using Pyrodex as a substitute for black powder in a cap and ball revolver, it is recommended to use a 1:1 volume ratio. This means filling your powder measure to the same level as you would with black powder to achieve comparable results.

What is the recommended loading for Triple Seven in cap and ball revolvers?

Triple Seven is significantly more powerful than black powder. To match the performance of black powder, it is recommended to reduce the volume measurement of Triple Seven by approximately 15%. This adjustment helps prevent over-pressurization and ensures safer operation.
