I guess even Dillon makes mistakes. I went to switch my 650 from 9mm to 40SW for the first time today. The only problem is only two number 2 buttons. I have had that caliber conversion sitting on a shelf for well over a month and never opened it. I guess it serves me right for not inventorying it until I wanted to use it. I sure hope the local dealer has one I can buy. I know Dillon will send me one I just wanted to load up some ammo for the weekend.
