If you're casting your own bullets, you know that alloy composition is everything—hardness, velocity, and accuracy all depend on getting the mix right. Brownells Pure Tin Casting Metal gives you a clean, straightforward way to dial in your custom alloys without guesswork. Tin is a premium hardening agent for lead-based bullet casting alloys, and this 1-pound bag of pure tin pieces lets you add just the right amount to match your specific load profile.
Tin melts readily at casting temperatures, making it easy to blend into your molten lead or existing alloy. The pieces are sized for convenient handling—roughly ½" long and ½" in diameter—so you can add them gradually and achieve consistent results batch after batch. Whether you're fine-tuning hardness for a particular cartridge, velocity window, or shooting distance, pure tin gives you precise control over your finished bullet's performance on the range or in the field.
The ballistic principle is straightforward: adding 1% tin by weight to your lead base increases Brinell hardness by approximately 0.3 points, giving you a predictable way to harden soft lead or adjust an existing alloy. That level of control is invaluable if you're experimenting with different powder charges, velocities, or target applications. Weights are approximate, and this product is sold by the bag—all the more reason to keep notes on your casting sessions and dial in what works best for your reloading bench.
