Lee Black Powder Minie Mould - Single Cavity .454" 298 gr

The Lee Black Powder Minie Mould - Single Cavity .454" 298 gr is a precision casting tool engineered for shooters who reload black powder rifle ammunition. This single-cavity mould produces consistent .454-inch diameter projectiles at 298 grains, the ideal weight for period-correct rifles and modern reproductions firing black powder loads. Lee Precision's aluminum construction delivers a practical balance: the material resists rust degradation inherent to iron or steel moulds, while cooling faster between pours—a critical advantage during extended casting sessions at the bench.

CNC machining ensures uniform cavity geometry and dimensional accuracy shot to shot. The .454" specification matches the bore diameter of rifles like the 1861 Springfield, Enfield, and modern inline replicas, while the 298-grain mass delivers the ballistic performance shooters expect from these platforms. Aluminum's inherent lightness—approximately 33 percent less mass than traditional iron moulds—reduces operator fatigue during high-volume casting runs. The mould's compact dimensions (2.6 x 2 x 10.7 inches) fit standard casting setups and storage without requiring dedicated bench space.

This mould serves Civil War reenactors, historical rifle competitors, and dedicated black powder hunters who demand ammunition tailored to their firearms' specifications. Single-cavity moulds require more pours per casting session than multi-cavity designs, but offer superior control over cooling rate and dimensional consistency—factors that matter when precision and historical accuracy define the shooting experience. Compatible with standard Lee casting handles and lead pots.

Black powder rifle reloading differs fundamentally from centerfire metallic cartridge work: bullet casting is the primary driver of cost savings and consistency. A reliable mould becomes the foundation of that workflow. Lee's track record in casting tool manufacturing and this mould's straightforward single-cavity design make it a dependable choice for shooters committed to hand-casting ammunition.
