Lee Black Powder Minie Mould, .533 Caliber 410gr, Single Cavity

The Lee Black Powder Minie Mould in .533 caliber (Lee part no. 90473) is a single-cavity mould well suited to reloaders casting their own conical minie balls for black powder muzzleloaders. Like other Lee moulds, its aluminum construction resists rust and is lighter than moulds made from steel or iron, letting it heat up and cool down more quickly during a casting session. That lighter weight also means roughly a third less fatigue for the caster compared to steel or iron moulds, and the block is CNC machined for perfect roundness and consistent bullet sizing, though note that the mould is sold according to weight for a suggested alloy and slight variances can occur with different lead mixes.

Frequently Asked Questions

What is this mould used for? Casting .533 caliber minie balls for black powder muzzleloaders.

Why does Lee use aluminum instead of steel or iron? Aluminum resists rust, heats and cools faster, and weighs roughly a third less, reducing caster fatigue.

Will actual cast weight always match the listed 410 grains exactly? The mould is sized for a suggested alloy, so slight weight variances can occur depending on the lead mix used.
