Lapua is always top of the totem pole, unfortunately, they don't make brass for any belted calibers... I do use Lapua for all the calibers I can, simply becasue it is the best brass I've ever used. Nosler or Norma is next in line. Then Winchester or Hornady. Then Remington, then Federal at the bottom of the barrel.
Everyone has different experiences, and that is just my personal pecking-order for brass, based on my experiences.
Some folks have great experiences with Federal, some have bad with Nosler and Norma... You just never know.
I normally use Nosler for my belted magnum calibers, but I couldn't find any when I got my .300WM. So for it, I have about 150 new Norma .300WM cases sitting here. I have good expectations for it.
