Lee Round Ball Mould (Handles Included) - Double Cavity .380" 82.37 gr

The Lee Round Ball Mould (Handles Included) – Double Cavity .380" 82.37 gr is a precision casting tool purpose-built for shooters and reloaders who produce their own round ball projectiles. This aluminum-construction mould delivers consistent, repeatable results for both historical black powder applications and modern reloading work. The double-cavity design allows efficient production of matched pairs in a single cycle, cutting casting time compared to single-cavity alternatives.

Lee Precision engineered the block halves using CNC machining to minimize stress concentration and eliminate dimensional drift that occurs with hand-finished moulds. The .380" cavity produces a finished ball weighing 82.37 grains when cast from lead—a critical specification for shooters calculating powder charges and verifying ballistic consistency. Aluminum's thermal properties allow rapid heat cycling: the mould reaches casting temperature faster than steel or iron alternatives and cools between pours quickly enough to maintain production rhythm without downtime. The included handles provide safe, ergonomic control during the pour and ejection sequence, eliminating the need for aftermarket purchases.

This mould serves precision handloaders, black powder cartridge competitors, and muzzleloading enthusiasts who demand uniformity across their ammunition components. Those working with period rifles, historical cartridge calibers, or specialty loads requiring exact projectile weight specifications will find this Lee mould delivers the dimensional accuracy and repeatability that separate careful reloading from casual ammunition assembly. The double-cavity configuration justifies its place in any serious casting setup where productivity and consistency are non-negotiable.
