RWS is very good and only needed the usual prep. But expect it to form out to the chamber quite a bit on the first firing. I haven't noticed this causing a need to redo load work up but it does form out increasing case capacity a bit. Running RWS I have found the need to reduce max charge by 3 gr with heavy bullets over the larger capacity cases. But the rise in pressure from the lower case volume does not loose that much velocity.
I use Lapua for my own rifles. Very hard to find but I have a stash (not for sale)
The Lapua is the most consistent cases and requires less prep. It also has the upper end of case capacity and has proven to get best velocity with heavy bullets for me. I have yet to wear any out as I use bushing dies to reduce brass overworking during sizing and I anneal too.
