I've been using Hodgdon's US869 in the 300 RUM with Berger 210 VLD bullets. 101.1 gr of 869 gives me 3,150 ft/sec in a 27" Broughton bbl with single digit SD. Accuracy @ 200yds has been .5 moa and better. Pressure appears to be less than any other loads that I've tried. Has anyone else been using 869 and heavy bullets in their RUM?
