Lee auto drum or auto disc, regardless you'll need the Lee powder through charging die or the flaring die as the die insert activates the "auto" feature of those measures.
By "lee pro" do you mean the Pro Auto Disc? The Lee Auto Disc (and the Pro version) work with Lee's powder through charging and flaring die. I don't know if it works with any other brand of dies, so I hope you ordered a die to go with it.
