I noticed first run brass was mentioned being tried on a LNL. I would not envision that on any progressive.
I would get all the “cooty bugs” out of the way on a single stage press first before venturing into the realm of “progressivism”
First full length, trim to length, primer crimp removal, inside and outside mouth deburring etc. unless you are doing the length trim via a Dillon press mounted unit but the still leaves a primer crimp to deal with.
