I've loaded thousands of rounds with a Lee turret press and I eventually preprimed any brass I was going to load with a RCBS auto primer first, after sizing with a single stage and then doing all the brass prep first; sizing, flash hole work and uniforming the primer pocket.

Since I measure every load for my .223/5.56 loads for accuracy what I would do is have one for powder drop, next bullet set, another for powder drop and another for bullet set. I had two small funnels sitting in the powder drops. It took a little time to get each bullet set exactly the same but when done I would have something going on every pull and not have any empty stages since I do not crimp that round.

You can see it on the right side of the picture.
