What works for me with rifle brass is to deprime and size, clean and reprime. Then place primed clean brass in the turret and charge, bell cases and seat. I shoot 60% lead in rifles.
With handguns I try for all at once. The main help here is a Lyman DPS 1200 that has the charge electronically weighed and is ready when I am, if I pushed the button. If I throw from a measure I prefer to weigh one of every 10 at minimum and that slows the process some.
