Lee Precision 90991 Double Cavity Bullet Mold .501 500 S&W Mag

The Lee Precision 90991 double cavity bullet mold delivers consistent .501 diameter bullets specifically engineered for the powerful 500 S&W Magnum cartridge. This aluminum mold produces two bullets per pour, doubling casting efficiency for high-volume reloaders who demand precision and speed.

What Makes This Different

Unlike single cavity molds that slow down production, this double cavity design cuts casting time in half while maintaining identical bullet dimensions across both cavities. The .501 diameter specification ensures proper bore engagement in 500 S&W Magnum revolvers, while the aluminum construction provides faster heat cycling compared to steel alternatives. Each cavity produces bullets with consistent weight distribution and balanced profiles for optimal accuracy.

Key Features

• Double cavity design produces 2 bullets per pour for increased efficiency
• .501 diameter bullets sized specifically for 500 S&W Magnum chambers
• Aluminum construction for rapid heat transfer and cooling cycles
• Precision-machined cavities ensure consistent bullet dimensions
• Compatible with standard Lee handles and mold guide accessories
• Self-aligning sprue plate design for clean bullet separation
• Heat-treated aluminum construction resists warping under high temperatures

This mold performs reliably with lead alloys ranging from pure lead to harder mixtures containing tin and antimony. The double cavity configuration maintains consistent fill rates even with lower-temperature alloys, producing uniform bullets suitable for hunting applications and target shooting. The aluminum material reaches optimal casting temperature quickly and maintains consistent heat distribution across both cavities throughout extended casting sessions.
