Lee Minie Ball Mold .540 Caliber 415 Grain
Single-cavity aluminum mold for casting .540 caliber Minie balls weighing 415 grains. CNC-machined for precision and consistency in black powder rifle ammunition.
Lee Black Powder Minie Ball Mold
The Lee Minie Ball Mold represents a practical solution for the black powder enthusiast who wants to cast consistent, accurate projectiles for period rifles and modern reproductions.
Design and Construction
This single-cavity mold is machined from aluminum, offering several advantages over traditional steel or iron molds:
- Lighter weight — approximately 33 percent less mass than steel alternatives, reducing hand and arm fatigue during extended casting sessions
- Superior thermal characteristics — aluminum heats and cools more rapidly, improving casting efficiency and consistency
- Rust resistance — no oxidation concerns, ensuring long service life with minimal maintenance
- CNC precision — each mold is machined for perfect roundness and dimensional control
Specifications
- Caliber: .540 inch diameter
- Bullet weight: 415 grains
- Cavity configuration: Single cavity
- Material: Aluminum
Practical Considerations
While this mold is sold according to weight for suggested alloy composition, minor variances may occur. This is normal and does not affect performance. The .540 Minie ball is suitable for rifles such as the 1861 Springfield, Enfield, and similar historical and reproduction black powder rifles.
For consistent results, maintain proper alloy temperature and allow adequate cooling time between casts.
