.40 Caliber Bullet Mold - 300 SP-CSA RCBS (.265)
Caliber .40 / .410 Mold for Casting Bullets - 300 Grain Weight
This precision-engineered bullet mold is designed specifically for casting .40 caliber and .410 bore projectiles, optimized for a 300-grain bullet weight. Manufactured with high-grade steel to ensure consistent cavity dimensions and superior thermal conductivity, this mold guarantees uniform bullet shape and weight, essential for achieving optimal ballistic performance in metallic and semi-metallic reloading applications.
The mold features a dual-cavity design, allowing for efficient production of multiple bullets per casting cycle, significantly improving throughput for handloaders and competitive shooters. Please note that this product does not include sprue cutters (tenazas), which must be acquired separately to complete the bullet trimming process.
For best results, it is highly recommended to use the top punch #378, reference R82520, which complements this mold perfectly by providing precise bullet seating and consistent bullet base formation. This combination ensures enhanced accuracy and reliable chambering in firearms chambered for .40 caliber and .410 bore ammunition.
Ideal for enthusiasts engaged in precision shooting, metallic cartridge reloading, and semi-metallic bullet fabrication, this mold is a critical tool for those seeking to optimize their ballistic load data and improve terminal performance through custom bullet casting.
