Found out something the seasoned loaders probably already know. I was struggling with fluctuating seating and crimping on my LNL progressive. Pulling bullets up the ying yang. What was giving me my inconsistancies was different amounts of pressure I was exerting on the press at the end of the cycle.
As I've become more consistant with the pressure I'm exerting on the downstroke, my seating consistancy has cleaned up a great bit. Might help some newbie rifle loader out like me.
