That is what I am trying to decide. I have #5PW which is 1oz. Previous to this PW machine I used a MEC with 1 1/8oz shot bushing and #33 powder bushing. I am loading reddot powder with WAA12CB wads in Win.AA hulls. To get close to what I am use to loading I would have to go to the #6 PW shot bushing,and a L or M powder bushing. If 1oz loads are good I could save money on the less ammount of shot in the shells, but don't want to sacrifice having fun hitting the targets
