Re: Number of reloads effect impact
I have done a lot of work in this area with my 308. I have found that I can get 8-10 reloads using Lapua with good ES without doing anything except trimming after 4 or 5 reloads. I found that the neck tension of the dye effects this. I seems the greater the tension, the more variability as the brass is worked. I size down .001-002" max and do not use an expander. I can feel a difference in neck tension if it occurs and put that brass aside. Lapua is the most consistent I have tried and I now use it exclusively. I have found Winchester brass to to be thinner by a couple of thousandths and much harder to control neck tension with repeated reloading. Annealing helps a lot as you have found.
