    RLB2,
    The new Sierra Manuals and the Swift Manual have data on the 300 Ultra. You can also try the Accurate Reloading website. I have a 300 ultra and my prefered loads are

    165gr Swift Scirocco 96 grns H-1000 CCI Mag primer 3.650 oal

    150gr Swift Scirocco 94.6grns IMR 7828 CCI Mag Primer 3.650 oal.

    Hope this helps.
