H4350 for 300WSM. Anything better?

I have a .300 WSM and .270 WSM, and they both like different powders. The .300 WSM likes H100V and H4350, the .270 WSM really likes Magpro.
 
I was thinking those might be a little slow for the 190s but I'm willing to try. I have four pounds of H1000 and about 10 of MagPro leftover from when I was shooting a 7WSM.
Hodgdon lists 72c grains max with a 200 grain bullet and 57200 psi. I popped primers at 71.5 grains with Norma brass and a 200 grain eldx.
 
I will second RL17 being the top powder, RL25 was the top powder prior to RL17 when I played with 25-300WSM, 6.5-300WSM & 33-300WSM. The latter liked RL19 the most.
When I worked up loads for several 300WSM rifles later on, only 2 powders stood out, RL17 & H4350. I tried Supreme 780, as this is what I was told Winchester used, albeit a bulk powder, but never got their ballistics, fell short by 100fps. Still have that powder, great in several other magnums and the above listed wildcats.

Cheers.
 
Looks like I misspoke in my earlier post. If you want velocity, RL26 is it.

My case is an improved case but it screams with RL26.
