When you say sort - are you asking whether you should separate brass by brand? As in you shot some Rem UMC, Win white box, and some PMC, and now want to reload all of them in one batch?
Personally, I don't like mixing brass. Guys do it all the time, and if you're running your charges in the middle of the road, and not expecting supreme accuracy, you probably won't see any negative effect. Just not for me. It's too easy to build lots of the same brass for me to bother with mixing.
