Lee Double Cavity Mold .530 Round Ball W/handles

If you're casting round balls for muzzleloading, percussion cap rifles, or other blackpowder applications, the Lee Double Cavity Mold .530 Round Ball with Handles offers a straightforward, economical way to produce consistent projectiles at home. This aluminum mold is designed to cast .530-diameter round balls and comes complete with handles, so you're ready to start producing bullets right out of the box.

Lee built this mold from aluminum rather than steel or iron, a choice that brings real advantages to the casting process. Aluminum resists rust, weighs less, and heats and cools faster than heavier metals—that means quicker cycles and easier temperature management when you're working at the furnace. The block halves are CNC-machined to tight tolerances, reducing the risk of fatigue cracking over repeated use and producing smooth, round finished balls with minimal sprue work.

The double-cavity design lets you cast two balls per pour, speeding up production compared to single-cavity molds. Whether you're a dedicated blackpowder hunter stocking up for the season, a serious reenactor, or a reloader who prefers to cast their own lead, this mold delivers the reliability Lee is known for without unnecessary complexity or cost.
