    Does anyone out there have any load data they would like to share for the 338RUM for 250grain SMKs or 225grain Barnes MRXs?

    I have an HS precision 338 RUM that I have had for a couple of years, but have done very little load development with it as my focus has been on other rifles I hunt with more.

    HS shipped the rifle with a test target showing a nice .5" group with 250SMKs. They list the load as 92grains of RL22. That seems pretty hot to me. I just got in box of the 225grain MRXs and plan to try them in the RUM and my 338 Kahn. Any input from you guys out there shooting these bullets would be appreciated.
