can anyone tell me if wc872 powder is compatable with a 300 ultra-mag, and if so a starting load for 180 accubonds?

I have used WC-872 in the 300 with Federal cases, 215 Federal primers and 180 grain AccuBond and 180 TXS my top load was 115 Grains and velocity topped out at 3376 FPS this is as much powdet as I could compress into the case. Also 112 grains with 200 grain AccuBond yielded over 3200 FPS ( I don't recall exactly)
range it,check the wind, dial in correction, aim and only one shot
