Superformance in 300WSM

[glockky]

I have a pound of superformance powder i bought before doing some research and found out there is not alot of caliber options its good for. I am getting a 300 WSM this weekend and dont have alot of time for experimenting before rifle season due to work schedule. Have any of your guys found superformance to work good in 300 WSM and if not what powder do u like for it?

It's more a matter of being a new powder having a lack of data at this point. It appears to be a great match for the 300 WSM, according to www.hodgdon.com, using a 165gr bullet.
You will have to try some loads to check for accuracy, because there can be a difference between someone's pet load and your own rifle.

I've tried Superformance in a 22-250; a cartridge it's designed for and wasn't all that impressed with the accuracy obtained. Accuracy was adequate but not impressive.
