Lee Black Powder Minie Mould - Single Cavity .575" 472 gr

The Lee Black Powder Minie Mould – Single Cavity .575" 472 gr is a precision casting tool designed specifically for blackpowder cartridge and muzzleloading ammunition reloading. This single-cavity mould produces consistent, round projectiles weighing approximately 472 grains, making it ideal for period-correct historical firearms, modern blackpowder rifles, and traditional muzzleloader enthusiasts who demand accuracy and repeatability in their handloaded ammunition.

Lee Precision engineered this mould from aluminum to deliver superior thermal performance compared to steel or iron casting moulds. The aluminum construction enables faster heating and cooling cycles—critical for sustained casting sessions—while reducing operator fatigue through its lighter weight (approximately 33 percent lighter than steel alternatives). Each mould is CNC machined to exacting tolerances for perfect roundness and precise bullet diameter control, ensuring consistent ballistic performance across your loaded ammunition. The .575" cavity produces a projectile sized for authentic Minié-type rifles and compatible blackpowder systems requiring this bore diameter.

This mould serves the reloading community—from historical reenactors and Civil War firearms enthusiasts to serious blackpowder hunters and long-range rifle competitors who rely on hand-cast projectiles. The single-cavity design prioritizes quality over production speed, allowing meticulous attention to each casting. Blackpowder shooting demands consistency and authenticity that only precision-cast ammunition delivers, and this Lee mould provides the tool necessary to maintain tight groupings and reliable performance across extended shooting sessions or hunting applications.
