300 wsm w/175 smk

[boltman223]

Hi,

I was wondering if anybody has a powder charge noad that has worked good for them or a ballpark figure for a 300wsm with Sierra 175 smk's? I wanted to tests a 300wsm out and 175's is all I have handy at the time.

I have H4350, H414, H380, and varget. I'm not opposed to getting any other powders.

Thanks in advance.

I have no experience with the 300WSM... Until others chime in I'll state the obvious by saying Hodgdon lists a max of 65gr of H-4350 and Quickload predicts 66gr as max charge weight.

Out of the powders you have, H-4350 is a clear winner for your application. H-4831sc would be my second choice if accuracy doesn't pan out with H-4350.
