The Lyman Multi-Expand Charge Die System is made from strong and durable steel. Considering the high-quality materials and workmanship, this is an affordable product. Because of the hollow expander design, reloaders have the ability to expand a case and drop powder simultaneously while keeping the powder measure mounted to the top. This die system is made to fit all of the standard powder measures; the shell holder is sold separately. Included with the system is an expander body, nonexpanding universal powder drop tube, and hollow expanders for 9mm, 10mm/.40 S&W, .38/.357, .41, .44, and .45.
