Mold 457-405-F (Caliber 45/70) for Precision Bullet Casting and Reloading
LEE 2-Cavity Bullet Mold for .45-70 Government Caliber
This precision-engineered LEE bullet mold features two cavities designed specifically for casting .457-inch diameter, 405-grain flat-nose (F) projectiles suitable for the .45-70 Government cartridge, as well as compatible rounds like the .458 Winchester Magnum (W.M.) and similar calibers. Crafted to meet the demanding requirements of metallic and semi-metallic reloading enthusiasts, this mold ensures consistent bullet dimensions and optimal performance.
With a ballistic coefficient of approximately 0.225, these bullets offer reliable external ballistics for hunting, target shooting, and tactical applications where accuracy and terminal performance are critical.
LEEs 2-cavity molds represent an excellent balance between quality and affordability, making them a preferred choice among precision reloaders who seek durable, high-performance casting tools without excessive cost.
Constructed from high-grade aluminum blocks, these molds provide superior corrosion resistance compared to traditional iron or steel molds. Aluminums thermal conductivity allows the mold to heat and cool more rapidly, reducing cycle times during casting sessions and improving overall efficiency.
Additionally, aluminum molds weigh approximately one-third less than their iron or steel counterparts, significantly reducing operator fatigue during extended bullet casting operations. This ergonomic advantage enhances user comfort and productivity.
The mold halves are securely clamped together using robust wooden-handled tongs, ensuring zero movement or misalignment during the molten lead pouring process. This tight closure guarantees uniform bullet shape and precise weight consistency.
Note that bullet weights may vary slightly depending on the specific lead alloy composition utilized during casting, so reloaders should verify weights for optimal load development.
The included tongs feature durable wooden grips for safe handling and improved thermal insulation, protecting the operator from heat exposure.
A practical integrated sprue cutter efficiently trims excess molten lead from the bullet base, facilitating quick release of finished projectiles and minimizing post-casting cleanup.
For best results, it is highly recommended to thoroughly degrease the mold before initial use and periodically thereafter. Applying a light coat of mold-specific seasoning or smoke treatment enhances bullet release and extends mold life.
Never lubricate the interior cavity of the mold, as this can degrade bullet surface quality and cause casting defects.
Lightly lubricate the sprue cutter retaining screw to maintain smooth operation and prevent seizing.
