Lee aluminum bullet molds are designed for efficiency and ease of use, offering a superior experience for bullet casters. Aluminum molds heat and cool faster than iron or steel, allowing good-quality bullets to be produced after just a few casts. Lighter than traditional iron or steel blocks, these molds reduce fatigue during extended casting sessions, making them ideal for high-volume bullet production. To ensure precision, the mold block halves are CNC-machined for exceptional roundness and size control. This mold casts one R.E.A.L. bullet and one round ball bullet. The R.E.A.L. (Rifling Engraved At Loading) bullet is engineered for easy loading, even in fouled barrels, thanks to its unique cleaning action. It delivers stable, non-tumbling flight, making it an excellent choice for hunting with heavy loads. Additionally, R.E.A.L. bullets maintain accuracy even in oversized barrels, ensuring reliable performance across a range of shooting conditions. Weights listed are based on Lee's suggested alloy; actual weight may vary depending on the alloy used.
