Lee Round Ball Mould (Handles Included) - Double Cavity .360" 70.04 gr

The Lee Round Ball Mould (Handles Included) – Double Cavity .360" 70.04 gr is a precision casting tool purpose-built for reloading and ammunition production. This double-cavity mould produces consistent .360-inch diameter balls at 70.04 grains, ideal for muzzleloading rifles, pistols, and historical firearm enthusiasts who demand repeatable projectile weight and geometry for accurate ballistic performance.

Constructed from high-quality aluminum, the mould block halves are CNC-machined to minimize stress concentrations and fatigue under repeated thermal cycling. Aluminum's lower thermal mass compared to steel or iron allows faster heat absorption and cooling, reducing casting cycle time and enabling higher production throughput without compromising ball roundness or dimensional consistency. The included handles provide secure grip and thermal management during extended casting sessions, protecting hands while maintaining precise pouring technique.

This mould serves dedicated reloaders, black powder competitors, and shooters who cast their own ammunition for historical arms, patched-ball rifles, and precision muzzleloading systems. The double-cavity design doubles output per pour cycle compared to single-cavity moulds, making it suitable for those building ammunition stockpiles or preparing for multi-day range sessions. Consistent 70.04-grain balls ensure predictable ballistic performance, critical for accurate distance shooting where projectile uniformity directly affects group consistency.

Lee Precision has positioned this casting tool as an entry-point-to-intermediate solution in the round ball mould category, offering precision geometry and thermal performance at accessible pricing. Weighing 0.58 lbs, the mould is compact and portable, suitable for range-side casting setups or permanent reloading benches.
