I prefer a full case (98 to 100% case density) and the RUM will hold 100+grains of powder
so I would start using H 50BMG.
Retumbo will get you a little more velocity but sometimes reaches max pressure quickly
and below 95% case density.
The big RUM has free bore (Most of the new high pressure cartriges do) but don't worry about
it because the Accubond does well without touching the lands.
Us 869 would be another one to try.
