I also do batch loading. I clean, size and trim the cases, then I sit in front of the tv and hand prime them with an RCBS hand primer. Then put them in zip lock bags ready to load. Then when I am ready to load I have the cases already and only have to add powder and seat the bullet. Since I am using a single stage press.
However I am going to buy a Lee classic turret because I can still use it single stage or when I get a load worked up to where I want it, I could switch to the turret and run out a lot of them.
