I am getting ready to work up a load for a Savage Weather Warrior in 300 WSM using the 200-grain Partition. Does anybody have any loads that have worked well with that bullet? Noser says that IMR 7828 was the most accurate powder in their tests.

I use Viht N550...... in my 300WSM Dakota M-76 with 23" barrel

Standard disclaimer applies.....work up load for your rifle.

This one has a 26-inch, so velocities should be a little better. Thanks.
