The powders that I have on hand are
RL 23
H1000
Magnum
RL22
Any info would be appreciated.
First off, which 200 gr bullets. Secondly, when you know that, go to that manufactures load data. Simple concept really.
Yes simple concept except Hornady doesn’t show 300WSM data, Sierra doesn’t offer free load data. Not only that, some guys have been loading the 300WSM for over ten years. I’m thinking some of them might have some good insight on what works well and what doesn’t. In these times of hard to get supplies, it doesn’t hurt to try a few short cuts.
But if you just wanna be a smart ass, feel free, this is America.
