Hi everybody, I have a Lee 3-die set for .38 Special/357 Magnum. I have only ever loaded jacketed and copper plated bullets with it, but am planning on loading up some lead "boolits" soon. Do I need a neck expander die? I'm pretty sure all my expander die does is bell the case mouth. I'm planning on using 180 grain gas checked boolits, if that makes any difference.
