Re: 300wsm powders
Hello and welcome to LRH.com!
I have the same rifle ... good choice! I primarily shoot the 180 gr AB's in mine and I like H4350 for mine. If memory serves, I use varget for 110 gr vmax's out of it. IMR and H are very close to eachother and the H is much more temp stable than IMR. Reloader 17 would be another option, it is also very close to the IMR and H 4350. Standard LRprimers is all you need in the wsm.
I used to re-load but now I "hand-load".
