If you're casting bullets for black powder rifles or other traditional firearms, the Brownells 40 To 1 Bullet Casting Alloy is formulated to deliver the performance characteristics those loads demand. This 5-pound ingot contains virgin lead and tin blended in a 97.5% to 2.5% ratio, creating a softer alloy with a Brinell hardness of approximately 8.5. That lower hardness matters: it produces consistent expansion and excellent weight retention when bullets are fired at black powder velocities, making it well-suited for muzzleloaders, lever-actions, and other traditional shooting applications.
Brownells sources this alloy from virgin metals rather than scrap stock, which means you're adding clean, predictable material to your casting operation. Consistency in your casting alloy translates to consistency in your finished bullets—important whether you're loading for hunting, target work, or historical reenactment shooting. Each ingot weighs approximately 5 pounds, giving you a manageable quantity for home bullet casters.
Whether you're new to casting or have years of experience at the pot, having a dedicated alloy designed for black powder ballistics removes guesswork from your process. Mix this alloy with your casting technique and you'll have bullets optimized for the velocities and performance expectations of traditional firearms.
| Product Name | Brownells 40 To 1 Bullet Casting Alloy |
| Ingot Weight | Approximately 5 pounds |
| Alloy Composition | 97.5% Lead, 2.5% Tin |
| Brinell Hardness | Approximately 8.5 |
| Metal Source | Virgin metals (not scrap) |
Yes. The soft hardness rating and lead-tin ratio are specifically formulated to deliver consistent expansion and weight retention at black powder velocities, making it well-suited for muzzleloaders and traditional cartridge rifles.
Brinell hardness measures how hard the alloy is. A lower hardness (like this alloy's ~8.5) means softer bullets that expand more readily at lower velocities. This is ideal for black powder loads but less suitable for modern high-velocity centerfire applications.
This alloy is made from virgin metals, not scrap. That means you're starting with clean stock, which promotes consistency and predictability in your finished bullets.
"40 To 1" refers to the ratio of lead to tin in the alloy: 40 parts lead to 1 part tin, or 97.5% lead and 2.5% tin.
