Lee Modern Minie Mould - Single Cavity .500" 354 gr

The Lee Modern Minie Mould is a single-cavity bullet casting tool designed for shooters who reload muzzleloading ammunition. This .500" mould casts the classic minié ball profile — a conical projectile with a hollow base — weighing 354 grains per round. If you're casting bullets for Civil War-era rifles, modern muzzleloading hunting, or historical reenactment, a dedicated minie ball mould gives you control over bullet quality and consistency that factory ammunition simply can't match.

Lee Precision bullet moulds are engineered for durability and ease of use. The single-cavity design means you'll cast one bullet at a time, which suits shooters who value precision in their projectiles and don't need high-volume production. Minie balls are time-tested performers in rifled muzzleloaders — the hollow base expands under firing pressure to engage the rifling and stabilize flight.

Whether you're a dedicated muzzleloader hunter, a living historian, or a reloader who appreciates the craft of casting your own lead projectiles, this mould lets you produce consistent, quality ammunition on your own terms.
