This is what is confusing me. I know there is a difference between single, turret, and progressive. The 550b looks like a turret that you can make into a progressive. Is that what I understand?
From your first post, you said he wants to load basic 5.56 and some pistol rounds. IMO, if a person wants absolute precision rounds, then a dedicated single stage press would be best. But, that's not where he's at. Many have made superbly accurate ammo on a 550b, so it's capable of this task. The Dillon 550 isn't a Automatic progressive press ie: you need to manually advance the shell plate to the next station; where as a true auto progressive like the Lee Pro 1000, Hornady Lock n Load, Dillon 650/1050, advance it for you. The 550 is just the most versatile machine out there. I use my Lee Pro 1000 now just to decap brass really fast and keep the Dillon clean and Blue.
