I am looking at stepping up to a progressive 550 0r 650 mostly for loading my semi auto loads .45,9mm,223,.308. I may load 1000 rounds a month tops. Which one would you get? I see with the 650 there are more dam things to buy after you buy than I could even imagine. I am very picky with my hunting loads and will continue to do those with a single stage press. Thanks Jason.
