I use two presses. The first is a plain, simple single stage Lee press. This press I use for depriming with a universal depriming die and for sizing bullets with the Lee resizing kit. The other press is a Lee four hole rotary press. Once you get you dies in the four hole ring and adjusted, you never have to touch them again. You will need one ring and a set of dies for each caliber. I Use six. Also I use a Lee auto disc powder measure for all pistol calibers. I use a seperate auto disc for each caliber because you can't insert or remove the auto disc without removing the two dies on either side of it which defeats the purpose of using the rotary press, not having to re-set your dies everytime you begin reloading. I also use the micrometer adjustment instead of the little discs that they provide. It gives me infinite control of the powder load. For priming, I highly recommend the Lee hand primer. I like this method very much because I can deprime first and then tumble the brass. I can then sit and watch T.V. and prime 500 cases while watching "True Grit". This also allows the primerpockets to get tumble polished clean. this eliminate most, but not all of the primer pocket cleaning to be done just before priming the cases. There are also about a gazillion things that you don't think about at first, primer pocket cleaners, powder scales, powder measures if you reload rifle calibers. The auto disc wont deliver enough powder to load the larger rifle calibers. You will also need a tumbler, especially if you shoot BP, a case lube and neck lube set up if you reload bottleneck cartridges, loading blocks (yes, they are a necessity), and there are a number of other "optional" things. I try to use carbide dies as much as possible and I have just about all of the optional toys that I really, really need when I need them but I only rarely need them, such as bullet pullers. All in all reloading for six calibers I have about $400 dollars invested in reloading tools and probably that much again in powders, primers and bullets.
