Slower powders, compared to RL-15, would be ok as they only fill up the case faster and give a little reduced velocity. Be cautious with faster powders. I have also used IMR 4064 successfully. My favored cast bullet load for .378 GNR is 50.0 grs of 4895 and any bullet north of 220 grs. I even have a crazy RNGC 350 gr. .375 mould! But that's getting a bit hot. The bullet seems to tumble and yaw on impact. I need to try and file a small flat point on it to see if that helps.
