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.
