Lee Round Ball Mould - Single Cavity (Handles Included) .690" 493.14 gr
The Lee Round Ball Mould—Single Cavity with included handles—casts .690" round balls weighing 493.14 grains, making it a practical choice for shooters and reloaders who want to produce their own projectiles affordably. Whether you're casting for traditional muzzleloaders, historical rifles, or experimental loads, this single-cavity mold lets you turn lead into finished ammunition on your own bench. Lee's aluminum construction keeps the tool light and manageable while heating and cooling faster than iron or steel alternatives—a real advantage when you're casting multiple rounds in a session.
The mould's CNC-machined block halves ensure consistent round ball geometry, and the hard anodized sprue plate stays securely fastened with tempered steel screws and spring washers, holding up to repeated casting cycles. At roughly 33 percent lighter than traditional iron moulds, it reduces hand fatigue during long casting sessions without sacrificing durability. The included handles give you immediate setup—no hunting for separate equipment before you can start casting.
If you reload ammunition or cast your own projectiles, a dedicated single-cavity mould gives you precision and speed without the learning curve of multi-cavity designs. This is honest equipment built for shooters who want control over their ammunition from raw lead to finished round.
