The Lee Precision 90431 features aluminum mold blocks constructed for exceptional molding qualities, with cavities CNC machined for unmatched roundness and size control. This double cavity mold produces a .401 diameter 175 grain semi-wadcutter nose bullet suitable for cartridges like 40 S&W and 10MM. Aluminum construction makes the mold rust resistant, and aluminum molds heat up and cool down faster than iron or steel molds, with good bullets typically produced after just a few casts, while the lightweight design reduces fatigue during extended casting sessions.
The mold comes with handles and sprue plate included, and most bullets cast from Lee molds can be used as-cast without sizing. The mold features machined aluminum blocks with a hard anodized sprue plate, a tangential cut-off design that helps eliminate the nip at the sprue cut-off, and includes hardwood handles. Lee Precision recommends smoking the mold with a wooden match, beeswax candle or a butane lighter for best results.
