I have a Dillon 1100 with Mark 7. When it indexes it is short of the stop and then it jolts to the final position. This causes major spills. You know…. I’ve tried adjusting the shell plate tightness, the adjustment screw in the back but nothing. Am I missing something? See the link. When it calibrates, it indexes perfectly.
