I ran into the exact same thing as you did with my 300WSM.

You are lucky as I am usually seeing 250-350fps difference from advertised speeds and what my chrony tells me.

If you are shooting sub moa then start *SLOWLY* working your loads up a half grain or so at a time until your group begins to start opening up. Then you can find your optimal speed vs accuracy point.
