When I had a Norma, the best powder I found was Retumbo.
Now that Vit N570 is availible, I would try that as well.

A good buddy of mine has a 338 Norma and he said the go to powder is N570.
It has performed well with 250 through 300 gr bullets.
He has shot some amazing groups, 5 shots in less than .2 at 100yds as well as very good results at 300yds.
He has yet to try it at 600-1000yds but will soon.
