Lee’s two-cavity bullet molds represent an excellent choice for precision handloaders and ballistic enthusiasts seeking high-quality bullet casting tools at an economical price point. These molds are engineered specifically for metallic and semi-metallic bullet casting applications, ensuring consistent projectile dimensions and weight uniformity essential for accurate shooting and reliable terminal performance.

Constructed from corrosion-resistant aluminum alloy, Lee molds offer superior thermal conductivity compared to traditional iron or steel molds. This enhanced heat transfer capability allows the mold to reach casting temperature quickly and cool down rapidly, significantly improving cycle times and enabling efficient bullet production during extended casting sessions.

The lightweight design of aluminum molds—approximately one-third the weight of iron or steel counterparts—reduces operator fatigue during the casting process, making them ideal for both novice and experienced casters who demand ergonomic handling and sustained productivity.

Each mold is securely clamped with robust wooden-handled tongs, providing a stable grip and precise alignment of the cavities to ensure consistent bullet shape and surface finish. The mold cavities are precision-machined to maintain tight tolerances, critical for achieving optimal ballistic coefficients and reliable gas check seating.

The indicated bullet weights may exhibit minor variations depending on the specific lead alloy composition used during casting, allowing handloaders to fine-tune their loads for maximum accuracy and terminal effectiveness.

Additionally, the molds feature an integrated sprue cutter blade that functions as a lead feeder channel, facilitating clean separation of the finished projectiles from the sprue. This practical design element streamlines the casting workflow and reduces post-casting cleanup time.

Ideal for casting 180-grain, round-nose bullets with a diameter of .309 inches, this mold is perfectly suited for reloaders working with .308 Winchester, .30-06 Springfield, and other cartridges within the .30 caliber family. The bullets produced exhibit a ballistic coefficient of approximately 0.317, optimizing external ballistics for medium to long-range shooting applications.
