For the money,,,, The 550 Dillon is the best way to go in my oppenion. It will load anything short of 50 BMG, is very fast to change from 1 round to another, turns out ammo that is at least as consistant as you can get with a single stage press, WITH BALL POWDERS, and is very fast. If you keep buying guns the Dillon will keep costing you money though. I load 7 different .22 cal. rounds alone. I load for several handgun rounds also, so I`ve got alot of tool heads and cartridge conversion laying around. But, then, I got my press in the early 1980`s so I`ve been adding things for years now. I have had several rifles that would shoot sub 1/2 moa groups with the ammo loaded on the Dillon and 2 that would shoot 1/4 moa regularly.
