Lee Double Cavity Mold - .500 Ball W/handles

The Lee Double Cavity Mold - .500 Ball W/handles is a precision casting tool purpose-built for reloaders and ammunition manufacturers who require consistent, uniform projectiles for historical cartridges and specialty loads. This double cavity design allows simultaneous production of two identical .500 diameter lead balls per cycle, significantly increasing output for shooters who cast their own ammunition or produce period-correct rounds for blackpowder rifles and revolvers. The integrated handles provide a secure grip during the pouring and cooling process, reducing handling fatigue during extended casting sessions.

Each cavity produces a finished .500 diameter ball weighing 187.64 grains—a specification critical for ballistic consistency and chamber fit in historically accurate or custom-built firearms. Lee's double cavity configuration maximizes efficiency by casting two projectiles simultaneously from a single pour of molten lead, reducing material waste and casting time compared to single-cavity alternatives. The mold is constructed to withstand repeated thermal cycling, with the handle design allowing for comfortable manipulation of the tool immediately after pouring without requiring external cooling aids or additional safety equipment beyond standard casting gloves.

This mold is ideal for dedicated reloaders working with .500 caliber blackpowder rifles, custom muzzleloaders, and specialty percussion revolvers where factory ammunition is unavailable or prohibitively expensive. Hobbyists engaged in historical reenactment, competitive blackpowder shooting, and collectors maintaining period firearms will find this tool essential for maintaining ammunition supply. The mold integrates seamlessly into any established lead casting setup using standard pouring furnaces and lead recovery systems. Proper mold preheating before each casting session ensures optimal ball quality and surface finish, extending mold service life and reducing casting defects.
