At RCBS, we take bullet casting seriously. RCBS Bullet Moulds are carefully crafted from solid cast iron blocks to strict tolerances, ensuring accurate, clean and repeatable castings, cast after cast. The mould blocks are precision-ground square before machining and steel alignment pins ensure perfect mating of the blocks, even with years of heavy use. Each RCBS mould block features a 3/16 inches thick steel sprue plate, securely held in place with tempered steel spring washers and screws for durability. With a wide variety of sizes and configurations available, RCBS Bullet Moulds accommodate many calibers and bullet shapes, making them ideal for everything from casual plinking at the range to precise hunting and target shooting. Whether you're casting for fun or for precision, RCBS Moulds provide the reliability and consistency you need.
