Nosler Brass 338 Lapua?

I don't have any experience with Nosler 338, but I do have 300 WM brass from them. All in all, the brass is ok. A little on the thin side, but not too bad. Only thing that was wrong was that the primer pockets weren't deep enough. Not a big deal, as I had a uniformer to fix the issue.
 
Shoot it and see, that's the only way to know.

Nosler brass, over the years, has been iffy despite all of the prep work being done before hand.

Lapua brass, for 338LM is pretty pimpy.

I'm on about 12-13 cycles with my stuff, going back a ways.
