Re: Primer issues with Dillon 550B
...from what I can tell, the large detend ball and related spring is installed properly. I put some vasoline on the ball and it seemed to accumulate some spilled powder during operation, so I assume it is seating into the shellholder OK.
What is kinda weird is that when I index the press, the shellholder bolt seems to tighten and then cause an index binding issue. It seems like I need to continually back out the bolt tension as the press operates.
