First thing it to get it installed properly. Mine is all the way in the back of the case feeder, the bottom corner is level, and the rfeeder sits at a 45 degree angle. Then you need to get the plastic shims more or less right for your bllet profile, then loosen the crew and get the offset of the shims such that the bases can just rotate past without callign off and the nose falls off to be flipped.
You can also slightly round the edgest of the plastic step ramp flipper thingy.
You can get detailed pics/tuning info from MBF. I think I have an old email / pics on this .... somewhere .... I think most of it made it to the support web site - dig in all the areas including rifle.
Are you now, or have you ever been a member of the Doodie Project?
