It makes the loading pass that much easier when you process before. You have way less issues and stops.
I hate stopping the press with a full load of cases. I end up yanking the case under and after the powder drop. Pour the powder back into the tub.
Then I have to keep this pile of cases with primers in them that I have to feed into the press after the primer station when I can. It’s a lot less of that crap and more loading 1k automated with only refilling bullets, powder, primers. You don’t even have to stop while you are doing that.
