I am wanting to reload for my 300 win mag. Will start with 165 grain Sierra HPBT Gamekings due to their performcance out of my 308. I know the heavier bullets will out perform in greater distances but this a starting point for me. I have RL 22, H4381SC, and H4350 on hand. Any ideas of your favorite loads even if not with this powder would be greatly appreciated.
