As Winmag stated I have used a number of Vihtavouri powders in my 300WSM's.
For the 165-68 grain bullets I have had good success with N550. With 185-90 grainers N165 worked very well. I have also used N560 with the heavier bullets but my success was not as good as with N165, so I think that you need to match the bullet weight with which powder you choose.
As far as comparing burn rate with H4831 I am not an expert, but I think N165 is a little slower than H4831 but it is very close. I have loaded N165 in a 270 Winchester and it takes just a bit more to achieve the velocity of H4831 but it worked great in my Ruger.
