Lee 2 Cavity Bullet Mold C457-500-F 45-70 Government (457 Diameter) 500 Grain Flat Nose Gas Check

Overview

The Lee C457-500-F is a 2-cavity bullet mold designed for casting .45-70 Government bullets. It produces a 500-grain flat-nose projectile with a .457-inch diameter, compatible with gas checks. The mold blocks are CNC-machined from aluminum, providing high thermal conductivity for faster heating and cooling, as well as reduced weight compared to steel or iron alternatives to minimize operator fatigue during casting sessions. This double-cavity mold enhances production efficiency by casting two bullets simultaneously. Lee Precision recommends avoiding spray-type mold releases, which can reduce cast bullet diameter; instead, the mold surfaces should be smoked with a candle, match, or butane lighter to ensure easy release. The mold is provided with handles and is engineered for consistent size control and roundness.
