Pet 300 Wsm Loads

[Buckblaster]

I have tested 13 different powders comparing accuracy and velocity with 150 gr Hornady in my Tikka T3 300WSM. My best velocity and accuracy came from 75 gr H4831sc. It chrono's at 3170 fps and groups less than an inch. H4831sc seems to be the best all around powder for the different bullet weights in my rifle.
