Depending on the cases variation in brass thickness you may not be able to get straight loaded rounds. I have seen where even when FL sized you still end up with banana cases after firing.
Have you checked or are ablentoncheck case and loaded round runout? If you find you get cases with a specific curve you could try marking the cases so the curve has a specific orientation to the chamber as you chamber them. Keep g every case that way.
Honest if the cases are the issue rather than trying to polish a turd I would chuck them or use them some other way and start with some good brass....lapua and then do the minimal prep they need. That way you take that variable out of play.
I'm with others for the 308 the 180 185s are all that's needed. But with a 10twist you should be gtg with 200s from a stability stand point.
