If you choose the RWS it is very strong brass, but also thick and has a lower case volume. I have found that with the RWS I need to run 3 gr less of H-1000, due to the lower case volume, than I do with Norma, Lapua , WW or RP. Norma also made the Lapua head stamp brass this is very good brass but like all Norma brass when running max loads the primer pocket will loosen faster than some other head stamps. I know Hornaday is not real hard either but not sure who makes it. I have no experience with Sako Brass, maybe some one will chime in here that knows it?
So if you want tuff brass the RWS is great and will last a long time. But you may give up a little velocity on top end loads. Some will say that pressure is pressure and when you get to max with both velocity should be equal. My results differ and I can get a little more velocity from a case with a little more volume. I use mostly H-1000 and load heavy for caliber bullets like 210, 215 and 230's in the 300 win. So that could have some baring on my results too.
