It will mount to the 650 without any real issue's Kajun. Here's what I did to my bullet tray years ago (pushes the bullet tray out about 2-3 inch's), it will allow the new Dillon mounting system for the bullet feeder to hook up to your 650 with no problem. And with the 650 there is no need for the extra short powder bar. It will work fine. Now the dillon will not work, without lot's of modifications, to a 1050 running on a Mark 7 auto drive. It also will not work any better, IE not at all, with full wad cutters then the MR BF.

Also ND I'm still using my MA powder funnel with no problems. The one dillon sends with the bullet feeder is the exact one that comes with any dillon conversion kit.
