Lee Round Ball Mould (Handles Included) - Double Cavity .454" 140.47 gr

The Lee Round Ball Mould with Handles Included (Double Cavity .454" 140.47 gr) is a precision casting tool designed for shooters and reloaders who cast their own projectiles for muzzleloading firearms and period-correct historical shooting. Part number 90442, this double-cavity mould from Lee Precision delivers consistent, uniform round balls essential for accurate ballistic performance in black powder rifles, pistols, and muskets across competitive and recreational shooting disciplines.

Constructed from high-quality aluminum, this mould resists oxidation and weighs significantly less than traditional iron or steel casting blocks—a critical advantage during extended casting sessions. The lightweight aluminum also cycles temperature faster, reducing cooling time between casting cycles and improving production efficiency. CNC-machined block halves ensure dimensional precision and minimize fatigue stress at contact points, directly translating to smoother, more uniform round ball cavities. The double-cavity configuration produces two identical projectiles per pour, doubling output compared to single-cavity alternatives without sacrificing quality or consistency. Integrated handles provide safe, ergonomic grip during the high-temperature casting process.

This mould serves committed muzzleloader enthusiasts, historical reenactors, long-range black powder competitors, and serious handloaders seeking complete ammunition control. Casting your own .454" round balls eliminates dependency on commercial projectile availability while reducing per-round material costs. The 140.47-grain specification is optimized for medium-bore applications, offering the ballistic profile and downrange energy required for hunting and competitive black powder events. Lee Precision moulds are recognized throughout the reloading community for straightforward operation, durability, and cost-effectiveness—making this model an accessible entry point for first-time casters and a reliable workhorse for experienced operators.
