try us 869 I like in 7mm and 7stw and my gunsmith uses it in his 338 and told me to try it in my stw and have never looked back

I'll agree with the 7828ssc or IMR 4350. I've used both in 25-06, 300WM and 338WM and they both work very well across a decent bullet weight spread. I used it in my 338 with 250gr bullets and it gave higher than expected velocities with a 22in barrel while other powders were lower. It is also seemingly easier to find than the "popular" powders. I will say that these loadings were in alaska and shooting temps ranged from 65 to -10

Initial testing for IMR 4350 in the 338WM is not looking too promising, but it is still very early yet.
The 300 WM really likes IMR 4350 and the 7mm RM has not been tested yet.
Thanks, Dennis

On personal experience my old 338 wm liked rl19. That and H4350.
