Get this:

and then run one of these on your station:

My issues went from 6-10 No-go rounds per 100 to maybe 1-2 but i have to be picky. Run the brass through the redding on a single station press, then run that brass through the undersized die on your progressive. Issue resolved. I also case gauge on my barrel that i'm shooting. Not an actual case gauge.
