Lee Round Ball Mould (Handles Included) - Double Cavity .319" 48.73 gr

The Lee Round Ball Mould (Handles Included) – Double Cavity .319" 48.73 gr is a precision casting tool purpose-built for reloaders and historical firearms enthusiasts who demand consistent round ball projectiles. This double-cavity aluminum mould produces two finished balls per cycle, significantly accelerating production compared to single-cavity alternatives while maintaining the dimensional consistency critical for ballistic accuracy in muzzleloading rifles, pistols, and period-correct firearms.

Constructed from high-quality aluminum rather than steel or iron, this mould delivers measurable advantages in field and bench use. Aluminum resists oxidation in humid storage conditions, weighs substantially less during extended casting sessions, and cycles through heat and cooling faster—allowing operators to maintain steady production rates without thermal fatigue degradation. CNC-machined block halves ensure uniform cavity alignment and produce geometrically smooth round balls free from casting defects that compromise ballistic performance. The .319" diameter and 48.73-grain specification match period ammunition standards used in mid-range caliber muzzleloaders, making this tool ideal for maintaining authentic loads or establishing baseline ballistic data for historical research and competitive muzzleloading events.

This mould serves competitive shooters, historical reenactors, and serious handloaders who cast their own projectiles for cost efficiency and ammunition self-sufficiency. Lee Precision's reputation in the reloading market rests on delivering functional tools at accessible price points without sacrificing dimensional accuracy or material durability. Included handles provide safe, ergonomic control during the casting cycle, reducing burn risk and improving repeatability across production runs. The compact 2.6 x 2 x 10.7-inch footprint fits standard reloading benches without excessive space demands.
