6 Cavity Mold 401-175-TC for Bullet Casting (Mold Only, Tongs Not Included)
LEE 6-Cavity Mold specifically engineered for .40 S&W caliber bullet casting applications
Bullet Diameter: .401 inches (401 diameter) with a 175-grain truncated cone (TC) profile optimized for precision and ballistic efficiency
Ballistic Coefficient (BC): .141, designed to enhance aerodynamic stability and terminal performance in metallic and semi-metallic projectiles
Manufactured for high-volume production of cast bullets, this mold facilitates rapid and consistent projectile fabrication essential for competitive shooting and tactical reloaders
Constructed from a robust aluminum block reinforced with corrosion-resistant steel bushings, featuring precision alignment pins to ensure exact cavity registration and minimal flash during casting
Aluminum molds offer superior thermal conductivity compared to traditional iron molds, enabling faster heat-up and cool-down cycles, which reduces downtime and improves casting throughput
Additionally, the aluminum construction reduces overall mold weight by approximately one-third versus iron counterparts, significantly decreasing operator fatigue during extended bullet casting sessions
The dual aluminum blocks are securely clamped using specialized mold handles (not included) to prevent any lateral or vertical movement when pouring molten lead or lead alloys, ensuring dimensional consistency and safety
Equipped with an anodized, extra-hard sprue plate and cutter mechanism engineered for clean, precise trimming of cast bullets, resulting in perfectly separated projectiles with minimal post-casting finishing required
Projectile weights may vary slightly depending on the specific lead alloy composition and casting parameters employed
Mold handles for opening and closing the mold are sold separately under reference number 90005 and are highly recommended for ergonomic and safe operation
Prior to initial use, it is critical to thoroughly degrease the mold cavities to eliminate any contaminants that could affect bullet surface quality; subsequent seasoning by smoking or applying a manufacturer-recommended mold treatment product is advised to enhance mold longevity and bullet release
Never apply grease or lubricant inside the mold cavities as this can degrade bullet quality and cause casting defects
Light lubrication of the sprue plate retaining screw is recommended to maintain smooth operation and prevent seizing during repetitive casting cycles
