We all know what Marlin--itis is, how many here have or are getting Dillon--itis symptoms ? ( Like Me )
I have a 550, 650 and 1050. The 550 says set up for large primers only. I use it to load my rifle ammo and handgun ammo that I don't shoot in large qunatities (480 Ruger, 41 Mag, etc). I have heard that the 550 takes more tweaking when changing primer sizes so I have just left it as is since it came from the factory.dugout said:Changing shell plates, dies and powder is quick and easy. The worst part is going back and forth from large primers to small primers as it takes some tweaking each time and the settings are not maintained. That is why I have two 550Bs. One is set up with large primers and one is set up with small primers and that is how I chose which press to use.
