Mold 515-500-F (Caliber 50-70) for Bullet Casting, Reloading, and Shooting
Lee Two-Cavity Mold for .50/70 Caliber Reloading
Designed for precision casting, this Lee two-cavity mold produces bullets with a diameter of .515 inches, weighing approximately 500 grains, featuring a flat nose profile optimized for consistent ballistic performance.
With a ballistic coefficient of .283, these projectiles offer reliable external ballistics suitable for medium to large caliber metallic and semi-metallic cartridge applications, ensuring stable flight and effective terminal ballistics.
Lees two-cavity molds represent an excellent balance between quality and affordability, making them an ideal choice for reloaders and handloaders who demand durable and efficient bullet casting tools without compromising on precision.
Constructed from corrosion-resistant aluminum alloy, these molds provide superior thermal conductivity compared to traditional iron or steel molds. This enhanced heat transfer allows for faster cooling cycles, increasing casting throughput and reducing overall reload time.
The lightweight nature of aluminum moldsapproximately one-third the weight of iron or steel counterpartssignificantly reduces operator fatigue during extended casting sessions, improving comfort and consistency in bullet production.
Each mold is securely clamped with wooden-handled tongs, ensuring a tight seal during the molten lead or lead alloy pouring process, which minimizes flash and produces clean, uniform bullets ready for sizing and lubing.
Note that bullet weights may vary slightly depending on the specific lead or lead alloy composition used during casting, so reloaders should verify weights for load development and accuracy optimization.
The molds incorporate a practical integrated sprue cutter blade that efficiently trims excess molten lead from the bullet base, facilitating smooth release of finished projectiles and minimizing post-casting cleanup.
Included with the mold are the necessary tongs for safe handling and operation, allowing reloaders to maintain control and safety throughout the casting process.
For optimal mold longevity and bullet quality, it is highly recommended to thoroughly degrease the mold before initial use. Additionally, seasoning the mold by smoking it or applying manufacturer-recommended mold treatments enhances bullet release and mold durability.
Under no circumstances should the interior cavity of the mold be lubricated, as this can adversely affect bullet surface finish and mold integrity.
Light lubrication of the sprue cutter screw is advisable to maintain smooth operation and prevent seizing, ensuring consistent sprue trimming performance over time.
