"station 2 has a 22-250 neck sizing die set high in the press
this knocks out media from 2nd tumbling and neck expands DOWNWARDS like a lyman M die."
Is there any particular reason for using a 22-250 neck sizing die instead of just taking a .223 small base die with expander and just backing it out a lot so that the only thing working the brass is the expander? Or did you just happen to have a spare 22-250 die laying around you wanted to put to use?
