I am interested in reloading. At this stage, I just want some feedback on what equipment would best suit my goals so I can start accumulating the components piece by piece. I was looking at the Dillon 650 as this seems to be a versatile press and well reviewed. I want the ability to load multiple pistol and rifle calibers, preferably a lot at once. I have read that it is best to start out on a single stage, and then advance to a turret or progressive. Is that necessary? Is there a press that makes for easy caliber swaps? Does anyone melt their own lead and is it worth doing so? Thanks.
