I would love to hear from anyone that reloads 300WSM. I am trying to reload with IMR 4350 and Barnes 3X bullets and am getting terrible results.

thanks Sprig

I had my best results with RL19. The trouble with the 300 wsm or any of the wsm's for that matter is the larger bullets take up too much room in the case, which means less room for powder.The Barnes buttets with their composition being lighter than lead, amkes this problem even worse.

Here are some 180 grain loads for you:

I load for a friends 300wsm in a Browning, no BOSS. His likes H4831 and a Barnes 168grTsx. We tried Rl19, Rl22, H4350 and Imr4350. Good results with RL19, but the best was with H4831. It proved to be an excellent elk load.
