Brownells Foundry Bullet Casting Alloy 5Lb Ingot

Casting your own bullets gives you complete control over load development and lets you recycle brass on your own timeline—but you need clean, consistent alloy to get repeatable results. The Brownells Foundry Bullet Casting Alloy 5Lb Ingot is made from virgin metals (not scrap), so you're starting with a known, pure composition every time you melt and pour. This matters: consistent alloy means consistent hardness, and consistent hardness means predictable velocities and accuracy.

Each ingot weighs approximately 5 pounds and delivers a balanced lead-antimony-tin mixture designed specifically for bullet casting. Whether you're loading for plinking, hunting, or precision rifle work, having foundry-grade alloy on hand means you can cast bullets when you need them rather than waiting on commercial ammunition or dealing with inconsistent scrap-metal loads. For reloaders who take bullet casting seriously, starting with virgin metal eliminates variables.

Approximate weight per ingot is 5 pounds. The composition is engineered to give you the hardness and flow characteristics serious casters expect—useful for everything from handgun loads to rifle bullets. Keep a few ingots in your reloading bench and you'll always have material ready when inspiration strikes or your cast-bullet supply runs low.

Frequently Asked Questions

What's the difference between virgin metal and scrap alloy for bullet casting?

Virgin metal is produced from pure raw materials and has a known, consistent composition. Scrap alloy comes from recycled sources and can vary in hardness, trace elements, and purity, making load development unpredictable. Brownells Foundry Alloy uses virgin metals so every pour has the same properties.

Can I use this alloy for both handgun and rifle bullets?

The composition and hardness of this alloy make it suitable for bullet casting, though the specific hardness and performance will depend on your mold design, casting temperature, and intended use. Consult your bullet mold documentation and load data for compatibility with your particular application.

How much alloy do I need per casting session?

That depends on your mold size and how many bullets you're casting. A 5-pound ingot gives you a known quantity to work with; the exact number of finished bullets will vary based on bullet weight and design. Plan accordingly based on your typical casting volume.

What does "approximate weight" mean?

Each ingot weighs roughly 5 pounds, but minor variation between ingots is normal in metal casting and handling. The composition remains consistent; minor weight variance won't affect your casting results.
