Overview
This casting alloy is intended for shooters who load bullets for Cowboy Action Shooting and standard blackpowder cartridges such as the 45-70 Government. It is a 20 parts lead to 1 part tin blend, with an approximate Brinell Hardness of 10, and is sold as a roughly 5-pound ingot. Brownells notes that it is made from virgin metals rather than scrap, which may matter to reloaders who want a clean starting material for their casting setup. Because ingot weight is approximate, it is best viewed as a practical shop supply rather than a precision-measured component.

Considerations & Trade-offs
- This alloy is relatively soft at approximately Brinell 10, so it is suited to the applications named in the description rather than harder-cast bullet needs.
- Each ingot weighs roughly 5 pounds, and the listed weight is approximate, so exact yield per ingot can vary.
- It is sold as a single ingot, which may be less convenient for buyers who want a larger bulk quantity or a precisely measured lot.
- The product is described for Cowboy Action Shooting and standard blackpowder cartridges such as the 45-70 Government, so it is a specialized casting alloy rather than a general-purpose option.
