There is another possibility

I think these new primed hulls may be longer than previous lots, maybe a card spacer?

You may be on the right track. You do sometimes need to tinker with the cam to deal with a hole in the center of the crimp. Straight from Mec: "Opening in center of shell. Correct by loosening the cam adjustment screw and moving cam down about 1/32 of an inch and try again."

Also compare the hulls you're using now to those you used previously. Hull length may be a contributing issue.
