Mold 457-450-F (Caliber 45-70) for 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 high-quality projectiles suitable for the .45-70 Government cartridge. Each cavity produces bullets with a diameter of .457 inches and a weight of approximately 450 grains, optimized for superior ballistic performance in .45-70 Government, .458 Winchester Magnum, and other similar calibers.

The bullets cast from this mold exhibit a ballistic coefficient of approximately 0.250, providing enhanced aerodynamic stability and improved downrange accuracy for hunting and target shooting applications.

LEE’s 2-cavity molds are highly regarded among metallic and semimetallic reloaders seeking reliable, cost-effective solutions without compromising on precision or durability. Constructed from corrosion-resistant aluminum blocks, these molds offer excellent thermal conductivity, allowing for faster heating and cooling cycles compared to traditional iron or steel molds.

Aluminum’s lightweight properties—approximately one-third lighter than iron or steel molds—reduce operator fatigue during extended casting sessions, making it ideal for high-volume bullet production. The mold halves are securely clamped together using robust wooden-handled tongs, ensuring zero movement during the casting process and guaranteeing consistent bullet dimensions and quality.

Note that the final bullet weight may vary slightly depending on the specific lead alloy composition used during casting. The included tongs feature ergonomic wooden grips for comfortable handling and enhanced safety.

Additionally, the mold incorporates a practical sprue cutter blade that efficiently severs the molten lead feed, facilitating clean release of the finished projectiles and minimizing post-casting cleanup.

For optimal performance and longevity, it is highly recommended to thoroughly degrease the mold prior to initial use. Seasoning the mold by smoking or applying manufacturer-recommended mold treatment products will further improve bullet release and reduce surface imperfections.

Important: Never lubricate the interior cavity of the mold, as this can adversely affect bullet quality and mold integrity. However, lightly lubricating the screw that secures the sprue cutter blade is advised to maintain smooth operation and prevent corrosion.
