Home Forums Reloading Big Game Rifles favorite powder 300 wsm with 165/168gr bullets?

I use 300WSM data for my 300 H&H since there is no data for this caliber in modern powders. Mine really like Hunter as well. My second choice is H4350.

could the advice in this thread be applied to a 7mm wsm using sierra gameking 160 gr. spbt?

My powder choices in 300 WSM:

150's 68 gr's W760
165's 65 gr's H4350
180's 65 gr's RL17

Have tried (other than listed): H4831, Imr 4831, Imr7828, Imr 4350, RL 22, H414, RL 25, Imr 4320 & Imr 4064. The worst group of any of these many bullet/powder combinations was 1.5".

I had good luck with H4350 and 165 gr SGKs in my 300wsm. I'm using 4831sc in my 7wsm with good results and they are pretty close.

thank you DocGlenn...... wyo.

I recently tried W760 and H4831sc... as in all other calibers I have, 4831sc worked the best
