What's the best powder or at least your favorite. I've tried Varget, and didn't get great results.

RL 19,RL 22 and RL 17.
I really liked what RL 17 did to the group sizes and the speed.

I might toss H414 in the mix. Both RL 19 & Rl22 will more than likly be compressed loads to push the max.

I worked up my loads in 2005 when I bought my rifle, so I haven't tried Rl 17 yet, but my best accuracy and highest velocity is with RL-19.

My hands down favorite 300 WSM powder is H 4350. I have worked up loads for six different rifles in 300WSM so far and they all shot quite well with H 4350.

Unless you are using LIGHT bullets you might give up velocity using RL17 not your RL19. If you have an accurate load with RL19 that you are happy with I sure wouldn't waste time and $$ trying RL17.

I've had good luck with:
Reloader-22
IMR-4350
Ramshot Hunter
Winchester 760

While I'm still not satisfied with the results of the 165 grain SSTs or NBTs, RL-19 is working the best. RL-22 did well too but IMR4831, IMR4350 and W760 didn't do as well.

The crazy thing is that H4895 and a 110 grain Vmax are the most accurate, go figure.

I haven't tried any other bullet weights.

H1000 with heavies.

Loads that have worked well for me with 165gr bullets:
65.0grs Win. 760 3150fps
65.0grs IMR-4350 3015fps
67.0grs Ramshot Hunter 3070fps
69.0grs Reloader-22 3030fps

With 180 grain bullets, mine likes H4831sc.

All I had when I loaded for a friend was DP-85, which Accurate/Western claims can be loaded using Ramshot Hunter data. I used 165-grain Speer GS and opted for one grain under max for that weight projectile, with Fed. 215s, brass trimmed to spec and flash holes de-burred. His Tikka shot them to .5 MOA at 100 and no pressure signs...

I settled for the speed and accuracy I was getting with Ramshot Hunter in the 150 to 165gr range. Very nice metering spherical powder too.

I've had pretty good luck with H-4350 and R-17 in the 300WSM's and 270WSM.

Mine likes 4350 and 4831.
