At RCBS, we take bullet casting seriously, ensuring every component is crafted with precision. Our Bullet Moulds are meticulously machined from solid cast iron blocks, made to exacting tolerances and specifications for consistent, clean and repeatable castings cast after cast. To guarantee perfect alignment, the mould blocks are precision ground square before machining and steel alignment pins are used to ensure flawless block mating even after years of heavy use. Each RCBS mould features a 3/16 inches thick solid steel sprue plate, securely held in place by tempered steel spring washers and screws for lasting durability. Available in a wide range of sizes and configurations, RCBS Bullet Moulds accommodate various calibers and bullet shapes, allowing you to cast for everything from plinking at the range to precision hunting or target shooting. With RCBS moulds, you can rely on exceptional performance and precision every time.
