I'm not making the brass you are but I make 6.5x58R Sauer brass from 9.3x72R brass. I have to anneal a couple times while forming and run it into the FL die a little at a time and then re -lube before I give it a little more. If I don't go slow and easy I will get ripples in the case.

LtoR 243, 6.5x58R Sauer, 9.3x72R

After the first shot the rest are just noise.
