I got a bunch of RWS .375 H&H Magnum brass with a used rifle I purchased, so I have experience with the cases but not loaded ammo.
The .375 H&H cases I had were fantastic. I know the .375 H&H is no benchrest rifle, but to pass the long winter I prep brass in front of the TV or stereo.
The cases were extremely uniform in weight, and the necks were very straight (I have one of those RCBS case gauge gizmos. Primer pockets were very uniform in depth, and there were no burrs inside the case around the flash hole.
The case heads are nice and hard so they do not show premature signs of pressure like the Rem cases I had did.
I anneal the necks about very dozen loads, and at that interval the case necks do not crack.
This is my only experience with RWS brass, but based on it, I would sure like to get a lot more!

PS: I have used a lot of Lapua brass too (although not in .375 H&H) and I would put the RWS on the same level.
