Brownells 20 To 1 Bullet Casting Alloy 5Lb Ingot

Handloaders who cast their own bullets need alloy that performs consistently and predictably. The Brownells 20 to 1 Bullet Casting Alloy is a virgin-metal ingot formulated specifically for shooters working with blackpowder cartridges and cowboy action loads. Made from 95% lead and 5% tin, this alloy delivers a Brinell hardness of approximately 10—the ideal balance of hardness and casting ease for traditional rifle rounds like the .45-70 Government and period-correct competition ammunition.

What sets this casting alloy apart is its use of virgin metals rather than recycled scrap. That means you're not introducing unknown contaminants or inconsistent composition into your casting pot. Purity matters when you're building ammunition you intend to shoot, and Brownells' approach gives you the clean, uniform product serious reloaders expect. Each ingot weighs approximately 5 pounds and is sized for efficient melting and pouring.

Whether you're loading for Cowboy Action Shooting matches, hunting with blackpowder rifles, or experimenting with cast-bullet loads in antique calibers, this alloy has been the standard choice among handloaders for decades. It's the right metal for shooters who want their cast bullets to size and perform reliably without the brittleness of harder alloys or the expense of premium lead alternatives.

Why does it matter that this alloy is made from virgin metals?

Virgin metals are pure and consistent in composition. Recycled scrap alloy can introduce unknown impurities that affect casting ease, bullet hardness, and performance. Handloaders who want predictable results choose virgin-metal alloys.

How much metal is in each ingot?

Each ingot weighs approximately 5 pounds. Weight is approximate due to the nature of ingot casting.

Can I use this alloy for jacketed bullet reloading?

No—this product is specifically for casting your own lead bullets. It is not used in conjunction with jacketed ammunition reloading.
