I have the Lee but not the patience to work the thing. There has to be better and easier testers to work than the Lee. Just saying. I gave up and just shoot water quenched WW for t the 9MM, 357Magm,44mag, and 40 cal. I air cool 38spl, 45acp and 45Colt. Water quench all my rifle bullets. Works for me.
