RWS is the best brass, end of story, but is it worth the price? I wish it was, but I mostly shoot PPU as its the cheapest brass out there, and its as good as WW, Rem,,..Norma IMO is just too soft and too expensive. Lapua and Nosler have good brass but if Im going to spend that kind of money I'll buy RWS..Basically I buy WW if available, same with PPU, if not then reach down into my pocket book and get RWS....which is seldom btw..Bottom line is all brass is about the same, with the exception of RWS...Mostly the difference in brass today is the condition the new brass comes from the factory, does it need to be shaped up before loading? yes it has bent lips, maybe some primer pocket clean up, whatever, but that's just time consuming and easy to do so you save a few bucks...The other best brass is IMI and its as good as RWS, but hard to come by in most calibers these days..I wouldn't get too anal about which brass I used, its all good enough...I have btw been using Hornady brass as of late, and its not up to snuff in several ways, but you can make it work, its just rough and sometimes out of specs, they have some work to do..
