    I am considering it, but all the rave about it seems to be based on using lighter bullets than i prefer for long range shooting, my 300wsm loves H4831, that would be the powder i would try first if i were in your position, unless you plan on using 150-175gr bullets, then i would go ahead and give it a try.

    AA Magpro was designed just for the WSM cases, but works in others well. Also if you like 4831SC, you need to hunt up a can of 3100.
