My very first and only load for my spanking new 300 RUM is
88.0 gr 7828 (Its what I had)
190 Berger VLD
Rem Brass
CCI Mag Primer
COAL 3.70"
There was no Berger load data to base it on, so I took the max loads for that powder for 180 and 200 gr noslers and split it.
No clue on the velocity, but I think it is relatively slow. Very accurate though, dime sized groups at 100 yards. I took it on its first hunt an hour after I threw the loads together and crushed a 12 pt whitetail at 160 yards. DRT.
Anxious to try some hotter loads through a chronograph. I think I'm in love with the RUM.
