IMO a new reloader should NEVER start on a progressive press ,I know the turret can be used as a single stage but most don't. A new reloader will mess up some ,the progressive press lets you do it faster and to more cases. I load on 2 rock chuckers for most things . I used the new cast iron Lee single stage and liked it ,a good starter press . I use Lee carbide pistol dies and factory crimp die for 357 mag 44 mag and 454.
When you have loaded for a while and want a progressive press look at Dillon , I have used a 550 for years and have never had a problem.
