I have a .338-06 Weatherby on the way. I am not sure whether to buy new .338-06 brass (expensive, but maybe worth it) or just resize some .30-06 brass to .338-06. If I were to resize, do I really need a full length resizing die if I use new .30-06 brass? Would a neck sizing die do the trick? I was thinking about getting a set of Redding Neck Sizing dies for resizing whatever brass I end up shooting through my Weatherby. Any advice? Thanks.
