.319 Caliber Bullet Mold
LEE Two-Cavity Bullet Mold for .319 Caliber Projectiles
Designed specifically for use with muzzleloading firearms as well as for precision handloading of hunting cartridges, this high-quality LEE bullet mold is engineered to produce consistent, accurate round balls ideal for a variety of shooting disciplines.
Constructed to support high-volume casting operations, this mold facilitates efficient production of lead projectiles with superior dimensional uniformity, essential for reliable ballistic performance in both black powder and modern metallic cartridge applications.
The mold features a robust aluminum block body reinforced with hardened steel bushings, ensuring exceptional durability and corrosion resistance under repeated thermal cycling. Precision alignment pins maintain perfect cavity registration, eliminating flash and ensuring uniform bullet shape with every pour.
Compared to traditional iron molds, the aluminum construction offers significantly faster thermal response times, allowing the mold to reach optimal casting temperature more rapidly and cool down quicker between pours. This thermal efficiency not only accelerates the casting process but also reduces the risk of lead sticking or cavity damage.
Additionally, the lightweight aluminum design reduces operator fatigue during extended casting sessions, enhancing comfort and productivity for reloaders and hunters alike.
The two aluminum blocks are securely clamped together using heavy-duty tongs included with the mold, preventing any unwanted movement or misalignment during the molten lead pouring phase. This ensures consistent bullet weight and shape, critical for precision shooting and reliable feeding in firearms.
Equipped with an anodized, extra-hard sprue plate that functions as a pour cup, sprue cutter, and flash remover, this mold guarantees a clean, complete cut of the cast projectile, minimizing post-casting cleanup and improving overall bullet quality.
Note that final bullet weights may vary depending on the specific lead alloy composition used, so reloaders should verify weights and dimensions to meet their ballistic requirements.
Included with the mold are the specialized tongs designed for safe and effective opening and closing of the mold halves during casting operations.
For optimal performance and longevity, it is highly recommended to thoroughly degrease the mold before initial use. Additionally, seasoning the mold by smoking or applying a manufacturer-recommended mold treatment product will enhance lead release and protect the cavity surfaces.
Never lubricate the interior cavities of the mold, as this can adversely affect bullet surface finish and dimensional accuracy.
Lightly lubricate the sprue plate retaining screw to ensure smooth operation and prevent seizing during repeated use.
