The Lee Original Minie Ball Bullet Mould is a single-cavity tool designed for casting .575-inch, 500-grain round balls used in muzzleloading and historical shooting. The mould uses rust-resistant aluminum blocks that heat and cool more quickly than iron or steel, reducing caster fatigue during extended sessions. For consistent roundness and size control the block halves are CNC machined.
