I thought I would try some 180 grain Accubonds out of my 300wsm. The only powder that the Nosler website shows that I currently have is R19. But I noticed that they show IMR4350 as an option, but not H4350. I do have some H4350 and hear about quite a few people saying they are using it in their wsm. I know there is a slight difference between the two but was wondering if maybe the Nosler reloading book or somewhere else shows data for the H4350?
