Lee Semi-Wadcutter Pistol Mould (Handles Sold Separately) - 6 Cavity .429" 240 gr

The Lee Semi-Wadcutter Pistol Mould with 6 Cavity and .429" diameter is a purpose-built tool for serious reloaders and ammunition manufacturers seeking consistent, high-volume bullet casting. This aluminum mould is constructed to CNC precision standards, producing .429-inch 240-grain semi-wadcutter projectiles suited for large-bore pistol calibers. The 6-cavity configuration enables efficient batch production, delivering reproducible results with minimal per-round variation—critical for shooters who demand consistency across magazine strings.

Aluminum construction offers distinct advantages over traditional steel moulds in sustained casting operations. The material's lower density reduces hand fatigue during extended sessions, while its superior thermal conductivity allows faster cooling cycles between pours—a measurable advantage when processing large quantities. Aluminum resists oxidation and corrosion, maintaining dimensional stability through hundreds of casting runs. The CNC-machined block halves ensure precise cavity alignment and gate consistency, translating directly to uniform bullet weight and dimensional tolerance. The 240-grain specification suits .44 Magnum, .44 Special, and similar large-bore pistol cartridges where semi-wadcutter profiles excel for hunting and defensive applications.

This mould serves reloaders who cast their own ammunition for both range training and field use. Semi-wadcutter bullets provide a distinct advantage: the pronounced shoulder engages the forcing cone cleanly, reducing leading in revolver cylinders and semi-auto barrels while delivering reliable expansion characteristics in soft-point or hollow-point variants. The Lee Precision design integrates seamlessly with standard Lee casting handles and accessories, though handles are purchased separately. Competitors in this space—including RCBS and Lyman—offer similar cavity counts, but Lee's aluminum approach prioritizes longevity and thermal performance over weight, making it well-suited for dedicated handloaders processing ammunition in volume.
