The Lee TL358-158-SWC Tumble-Lube Semi-Wadcutter Mould, .358-diameter, 158 grains (brand part no. 90321), casts a sharp-shouldered bullet for .357-caliber revolver reloaders, machined for Lee’s tumble-lube system rather than a traditional lube-sizer die. Bullets cast from this mould have grease grooves designed for Lee’s Liquid Alox tumble-lube coating, letting a reloader lube a batch of cast bullets by tumbling them in a bag rather than running each one through a separate lube-sizer machine. Lee offers this mould style across a wide range of grain weights, and the blocks are aluminum with steel handles permanently attached, staying rust resistant and light through a long casting session.
