Anybody shooting the .338 Norma Magnum? Reload for it?

Quite a while back I picked up some new Lapua brass for the .423 Dakota thinking about building a 400 but now I see that the .338 Norma Magnum is getting kind of popular and now that Norma has had it C.I.P rated dies, ammo, and brass are becoming available.

Seems like this .423 brass should form right down into this .338 Norma Mag. pretty easily, and maybe would be a better build.

Anybody do this yet?
