Lee 90420 Double Cavity .375 Caliber Round Ball Mold

Lee Precision 90420 Mold Double Cavity Round Ball .375 Diameter Aluminum/Wood Capacity 2 Bullets

The Lee 90420 Double Cavity Ball Round Mold is designed for casting round projectiles used in black powder muzzleloading firearms. Its dual-cavity design allows you to produce two .375 caliber round balls per casting cycle, making it a practical choice for shooters who cast their own ammunition. The mold is built from aluminum for lightweight handling and efficient heat transfer, while the included wooden handle provides a secure and comfortable grip during use.
The tangential cut-off sprue plate is designed to help eliminate the undesirable sprue nub commonly left on cast round balls. This feature supports cleaner projectiles with less finishing work after casting. The mold includes the required sprue plate and handle, providing a complete setup for producing round balls without needing to source these components separately. Lee’s straightforward design is suitable for muzzleloader enthusiasts, hobby casters, and users who value repeatable projectile production.
The Lee 90420 mold produces round balls with an approximate cast weight of 79.16 grains, depending on alloy composition and casting conditions. For best results, follow established lead-casting safety practices, use appropriate protective equipment, and operate the mold according to accepted casting procedures. Inspect each projectile before use to confirm consistent form and quality. With its two-cavity layout, aluminum construction, and integrated sprue management, this Lee round ball mold offers a reliable solution for casting projectiles for compatible black powder firearms.
