    Should work fine, & be a lot less work than mine.
    I had my long action 300WSM built on an old Model-70, 30-06 action. Had to open up the bolt face, massage the rails, adjust the bolt stop, get new bottom metal etc to accommodate the RUM/WSM case taper, & hone the feed ramp.
    Yours shouldn't take half that work since you've already got the RUM bolt face & bottom metal.
    Oh, I had er throated for 200gr Accubonds too.
    I went with a fluted #4 taper 26" Hart 10 twist.
    I've shot a few groups less than .25 moa C-to-C with 180 Accubonds & RL-17. Also added a Muscle Brake.

    A bit smaller than that. I hunt near vertical terrain, (see pic in my signature) & didn't want too much weight, but wanted bigger than a sporter bbl. for long range. Had mine fluted for weight not vanity:D. It's really not a whole lot more wt than a sporter, but looks bigger
