I have already purchased Brown's book. I read it immediately. It really helped me to decide what type of action to purchase. As far as caliber goes, I am strongly considering the 375 jdj or the 405 winchester. I'm still undecided though. For what I want a DR for I really would like a caliber similar to these two. I don't want something that is going to cost me $5 or more for one piece of brass. That's why I'm hoping to get some feedback from the guys on this forum.
