Overview
This casting alloy is intended for handloaders who want a softer material for bullet casting, especially in black powder applications. Formulated at 40 parts lead to 1 part tin, it is described as having a Brinell Hardness of approximately 8.5 and is sold as a roughly 5-pound ingot. The use of virgin metals, rather than scrap, is noted in the product data for those who prefer a cleaner starting material. Because it is a softer alloy, it is suited to shooters focused on consistent expansion and weight retention at black powder velocities.

Pros
- 40 parts lead to 1 part tin for a softer casting alloy formulation.
- Approximate Brinell hardness of 8.5 for consistent alloy softness.
- Designed for consistent expansion at black powder velocities.
- Promotes excellent weight retention in cast bullets.
- Made from virgin metals rather than scrap material.
- Sold as a roughly 5-pound ingot for casting use.
Considerations & Trade-offs
- This is a softer casting alloy, so it is intended for black powder velocities rather than higher-velocity applications.
- Each ingot weighs roughly 5 pounds, and the listed weight is approximate rather than exact.
- The product is sold by the ingot, so multiple units may be needed depending on your casting volume.
- The description references virgin metals and a Brinell Hardness of approximately 8.5, but those specifications still leave the alloy purpose-specific rather than universal for all casting needs.
