Yes. I got the paper Hull smooth crimp starter for the 12 gauge 600 jr years ago when I was shooting an reloading lots of Federal paper GM shot shells. I need to look into getting one for the 16 and 20 gauge 600's also. I'm lucky that the PW is set up with their crimp starter that works good on new unfired paper hulls. Then it's a snap to get a good crimp on the 600's. That's really my only complaint about the 600 is the crimp starter when using new never loaded new paper hulls.
