Lee Precision, Inc. .54 Caliber Mini-IMP Single-Cavity Mold, 0.533" 410 gr

Lee manufactures their mold blocks from aluminum, offering rust resistance and enhancing durability. Aluminum molds heat up and cool down faster than iron or steel molds, allowing for high-quality bullets to be produced quickly, often after only a few casts. Additionally, aluminum blocks are one-third the weight of iron or steel molds, minimizing fatigue during long casting sessions. To guarantee superior performance, each mold block half is CNC-machined to achieve unmatched roundness and size control. The weights listed are based on Lee's recommended alloy; however, actual weight may vary depending on the specific alloy mixture used.
