Mold C309-160-R (.30 Caliber) for Precision Bullet Casting and Reloading
Lee Two-Cavity Bullet Mold for .30 Caliber
Designed with a precise diameter of .309 inches, this mold produces bullets weighing approximately 160 grains, featuring a gas-check groove (R) compatible with Gas-Check caliber .308 Winchester, .30/06 Springfield, and other similar cartridges.
With a ballistic coefficient of approximately .252, these bullets offer reliable external ballistics performance suitable for medium to long-range shooting applications.
Lees two-cavity bullet molds represent an excellent choice for precision handloaders and metallic reloaders seeking a high-quality casting tool at an economical price point, optimized for both lead and semi-metallic bullet production.
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 heating and cooling cycles during casting, significantly improving production efficiency and bullet consistency.
The lightweight aluminum construction reduces the molds overall weight by approximately one-third compared to iron or steel counterparts, minimizing operator fatigue during extended casting sessions and enabling greater control over the casting process.
Each mold is securely clamped with robust wooden-handled tongs, ensuring tight cavity alignment and consistent bullet dimensions with every pour. The mold cavities are engineered to accommodate precise alloy flow, reducing casting defects and enhancing bullet uniformity.
Due to variations in lead alloy composition and casting conditions, the indicated bullet weights may exhibit minor fluctuations, which is typical in precision bullet casting operations.
Integrated into the mold design is a practical sprue cutter blade that functions as a lead feeder and cleanly severs the bullet from the sprue, facilitating efficient bullet release and minimizing post-casting cleanup.
The package includes durable tongs for safe and ergonomic handling of the mold during high-temperature casting procedures.
For optimal mold longevity and bullet quality, it is highly recommended to thoroughly degrease the mold prior to initial use. Additionally, applying a light coating of mold seasoning agent or smoke treatment enhances mold release properties and prevents lead adhesion, ensuring smooth casting cycles and consistent bullet finishes.
