I just purchased my first 6 cavity Lee mold. A 356-125. I never really considered these molds, and stuck with Lyman or Saeco 4 cavity. I always thought they were low quality, even though others gave decent reviews on them. Well I broke down and purchased one. I wanted a standard profile and weight for the 9mm, to add to my collection of molds. I have been casting for over 40 years, and have nearly 50 other molds.
This mold is really nice. The cammed sprue cutter works effortlessly, giving clean cut bases. Half the bullets drop out when opening the mold, with one tap of the mallet on the hinge bolt, drops the rest. I could not get this mold too hot. Casting at 800 degrees on my Pro-melt. I was casting as fast as I could, leaving mold sit for only about three seconds after the pour, before dumping the bullets. Completely emptying the pot, while dumping the accumulated sprue in twice, emptied the pot in less than 90 minutes. All clean bases, with no smearing on blocks or sprue plate. Maybe on the larger calibers, this would not be possible, but on this mold it is.
Of a tin enriched WW alloy, the bullets drop at just under .357, and weigh 127.5 grains. Very pleased with this mold, and would not hesitate to purchase another.
