IMR or H4831 in 300 wby?

[4xforfun]

I know that this isn't one of your choices, but, in all of the 300 BBls I have ever owned or loaded for (except one), the powder that always came out on top for me was RL 25. But I admit, I pretty much only shoot the heavys...200 grains or more. usually 210 VLD's.


Good luck,
Tod
