I'd be interested in seeing your results, loud. I'm in the process of loading some .300 WinMag myself, trying 180 gr. Hornady SST's and 180 gr. Nosler Ballistic Tips propelled by IMR 4350 (which, incidentally, does not meter well from a Dillon 550 powder measure).
I, too, will try and post results when I have them.
Cheers!
