At RCBS, we take bullet casting seriously. Our Bullet Moulds are precision-machined from solid cast iron blocks, crafted to exacting tolerances to ensure every casting is accurate, clean and repeatable. We precision-ground the blocks square before machining and use steel alignment pins to maintain perfect mating of the mould blocks even after years of heavy use. Each RCBS mould is equipped with a 3/16 inches thick solid steel sprue plate, tightly held in place with tempered steel spring washers and screws for durability. Available in a wide range of sizes and configurations, RCBS Bullet Moulds accommodate various calibers and bullet shapes, making them perfect for everything from casual plinking to precision hunting and target shooting. Whether you're new to casting or a seasoned pro, these moulds will help you achieve the results you need with every cast.
