Lee 90406 Double Cavity .311 Ball Mold with Handles

The Lee 90406 Double Cavity Ball Mold is designed for casting round projectiles suitable for muzzleloading applications. This mold produces two .311-caliber balls per casting cycle, helping streamline projectile preparation while maintaining a consistent shape. Its aluminum construction offers a practical combination of durability, light handling, and efficient heat transfer for repeat casting sessions.
The included sprue plate features a tangential cut-off design that helps eliminate the objectionable nib commonly left at the sprue. This design supports cleaner castings and can reduce the amount of trimming or finishing required before use. The double-cavity layout also improves productivity compared with a single-cavity mold, making it a useful addition to a muzzleloader loading setup or casting bench.
Lee supplies the 90406 mold with wood handles and a matching sprue plate for a complete casting solution. The mold is intended to form round balls with an approximate weight of 45.16 grains, depending on alloy composition and casting conditions. Follow appropriate lead-handling, ventilation, heating, and personal-protection practices whenever casting projectiles. With its straightforward design and included components, this Lee ball mold is a practical choice for shooters and reloaders who cast their own muzzleloader ammunition.
