Lyman, .358" diameter, 150 grain bullet mold, double cavity steel blocks only. These precision mold blocks are made in the U.S.A. and tend to cost a bit more than other brands. They are nice quality. Special steel alloy mold blocks hold heat, for even casting temperature. Steel blocks almost never wear out, if properly stored. Blocks are made in one size, cut with two cavities for small bullets. Mold handles are sold separately.
