Are you turning your brass?
That would be my question. If using multiple brands and runs of brass and a bushing die you are most likely going to have to turn necks.
If you have gone to the expense of hand dies and an arbor press you want to get the best you can get out of your loads. Cass prep including turning necks would be a given in my mind.
Being a
cheap thrifty old fart I turned my own bushing and seating hand dies and made my press out of an antique bottle capper. Including my bushing and press I am into my hand dies under twenty bucks and they work every bit as well and Wilson.
