Lee Black Powder Minie Mould, .45 Caliber 298gr Single Cavity

The Lee Black Powder Minie Mould in .45 Caliber, 298 grains, single cavity (Lee part no. 90469) is machined from aluminum rather than the traditional steel or iron, which gives the block natural rust resistance and lets it heat up and cool down far faster during a casting session. Aluminum is also roughly 33 percent less than steel and iron moulds, cutting down on caster fatigue during long or repeated casting runs. Lee CNC-machines the block halves for round, correctly sized bullets even in the first few casts, and the mould is sold by weight for a suggested casting alloy, though actual cast weight can vary slightly with the alloy used.

Key Specifications

• Single-cavity design. casts one bullet per pour, suited to low-to-moderate-volume casting.
• Cast weight of 298 grains. in .45 Caliber, the reference weight for the recommended casting alloy.
• Rust-resistant aluminum block construction. unlike traditional steel or iron mould blocks.
• Heats and cools faster than steel or iron. speeding up a casting session compared to a heavier metal mould.
• Aluminum block weighs roughly 33 percent less than steel and iron moulds. reducing fatigue on the caster during long sessions.
• CNC-machined block halves. produce round, correctly sized bullets even in the first few casts.
• Sold by target weight for a recommended casting alloy. actual cast weight can vary slightly depending on the specific alloy used.
• Suited to low-to-moderate-volume cast-bullet reloading. a single-cavity mould trades casting speed for the lower cost of a simpler tool.
• Natural rust resistance from the aluminum block. unlike a steel or iron mould, which needs more careful storage and maintenance.

Frequently Asked Questions

Why does Lee use aluminum instead of steel or iron for this mould? Aluminum resists rust, heats and cools faster during a casting session, and weighs roughly 33 percent less than steel and iron moulds, all of which reduce caster fatigue and speed up the process.

Will every cast bullet weigh exactly 298 grains? The mould is sold by target weight (298 grains) for the recommended casting alloy; actual cast weight can vary slightly depending on the specific alloy used.
