Lee Hollow Base Rifle Mould - Single Cavity .459" 405 gr

The Lee Hollow Base Rifle Mould - Single Cavity .459" 405 gr is a precision-engineered tool designed for handloaders who demand absolute consistency in their heavy-caliber casting operations. Primarily utilized for the .45-70 Government and similar large-bore platforms, this mould allows shooters to produce high-mass projectiles that offer superior stability and terminal performance. By casting your own bullets, you gain total control over alloy hardness and weight uniformity, which are critical factors for long-range accuracy in vintage and modern rifles alike. This specific configuration is essential for those seeking the traditional 405-grain weight profile favored by marksmen for over a century.

Constructed from high-grade aluminum, this Lee Hollow Base Rifle Mould - Single Cavity .459" 405 gr leverages the material's natural thermal conductivity to reach operating temperatures quickly and dissipate heat efficiently between pours. Unlike traditional iron moulds, the aluminum blocks are inherently rust-resistant, ensuring a long service life even in humid reloading environments without the need for heavy oiling. The single-cavity design ensures that every bullet produced is a near-exact clone of the last, eliminating the slight weight variances often found in multi-cavity alternatives. The precision-machined hollow base plug creates a projectile that expands upon firing to grip rifling securely, making it ideal for rifles with slightly worn or oversized bores.

Serious reloaders looking to buy a reliable casting solution will find that the Lee Hollow Base Rifle Mould - Single Cavity .459" 405 gr delivers the specifications required for match-grade lead projectiles. This mould is particularly effective for those shooting the "Trapdoor" Springfield or modern lever-action rifles where a .459-inch diameter is necessary for a proper gas seal. The lightweight nature of the blocks reduces fatigue during extended casting sessions, while the integrated sprue plate ensures clean cuts for a flat, consistent base. Whether you are preparing for a black powder cartridge match or a hunting trip, this tool provides the consistency needed to maximize your rifle's potential.
