    I have a reloading AP that is basically compiled data from Manufacturers websites and manuals.
    I would verify this below info from an actual manual to be sure. But this ap states:

    Accurate 4350 in 300 WSM
    Hornady 150gr BTSP
    63.5gr. starting to 70.8gr Max
    OAL- 2.800"
    2950fps. To 3285 fps.
    63,500 psi

    This is the only load I found for AA 4350 and 300 WSM 150 gr bullets.

    I don't think you screwed up, but it looks like you might be on your own. It's my opinion that not many shoot that light of a bullet in 300 WSM.
    I also found the some data in my older Hornady manual.
    It has a start of 60.0 to a max of 68.0, with various 150 to 155 grain Hornady bullets.
    Good luck

    Unless you use a tough mono like a Barnes or a premium Bonded bullet like a Swift you can expect a lot trauma. Not sure that would even work. I loaded some 150gr Accubonds in my 300WSM. They made mess of a whitetail at 50 yards. I have never seen one so mutilated.

    No you didn’t screw up!
    That’s an excellent powder that’s real close to the preferred H4350.

    Hodgdons has taken over marketing and distribution of Accurate and Western Powders.
    Hodgdons has online data for Acc4350.
    Starting with a Hornady 150 Spt is 63.5. Max is 70.0.
    Acc4350 is about as good as it gets with a 150 in a .300WSM.
    In my neck of the woods, that’s a very popular combo (.300wsm and 150gr bullet).
    The Nosler Partition and Accubond are popular. To 300yds, shoots really flat @nd expands well on our smallish deer.

    90 percent of my shots will be 150 or less unless I sit on the edge of a bermuda patch which would be 250 yards
