Lee Round Ball Mould - Single Cavity (Handles Included) .690" 493.14 gr

The Lee Round Ball Mould – Single Cavity .690" 493.14 grain is a precision casting tool designed for shooters and reloaders who produce round balls for muzzleloading firearms and historical reenactment. Constructed from aluminum, this single-cavity mould delivers rust resistance and superior thermal cycling—heating and cooling approximately 33 percent faster than iron or steel equivalents. The lightweight design reduces operator fatigue during extended casting sessions while maintaining the durability required for consistent, repeatable production of properly weighted projectiles.

Each cavity is CNC machined to exacting tolerances, ensuring that cast balls maintain roundness and weight consistency critical for ballistic accuracy. The .690" diameter specification produces 493.14-grain projectiles suitable for traditional rifle calibers and period-correct loading. The mould includes dual handles for safe handling during the casting process, allowing controlled pouring of molten lead while maintaining proper mould orientation. Single-cavity design means longer casting cycles per pour, but results in fewer flash lines and superior surface finish compared to multi-cavity alternatives.

This mould is ideal for dedicated shooters committed to traditional ballistics, Civil War reenactors, and serious muzzleloading hunters who demand precision-cast ammunition components. Lee Precision round ball moulds have established themselves as the cost-effective standard in the muzzleloading market, offering performance and reliability without the premium pricing of competing castings. Weighing 0.8 pounds with compact dimensions, the mould integrates easily into any reloading bench setup.
