Just picked up a new Ruger M77 Mark II in 300 Win. Mag. I will be reloading for it and was wondering if there is anything I should know about this fine round.

First off, I had a hell of a time finding brass. Got lucky and found three bags at a local Bass Pro Shop. Everyone else was out of stock. I will more then likely load up some 165 gr. and 180 gr. loads. Any suggestions on a good powder to use? I have been looking over different reload manuals , but none give any good info on what would be a better powder to use. I will be use this gun for hunting at moderate ranges.

Thanks.
