RE: Best factory load for 300 wsm...
I honestly started using the federals, but i changed to the just plain silver box of winchester X. i think it is 185 gr. Havent shot anythingwith them but they hold a better pattern than any other ones so far. I have a winchester m.70 featherweight, and honestly it doesnt kick bad at all. Smooth shooting and smooth bolt. great to shoot.
