Is it going to be Sir Rodeo, Sir Cooke, or Sir What ?

I have one good load for that bullet, it was another one-and-done 5-shot test over an Oehler 35P with a 100-yard target. That bullet is pretty soft, usually loaded to no more than 2100 fps in a .45-70, but you could start here and work down if it is too destructive of venison:
325-gr FTX COL = 3.300" seated long (seated on factory cannelure, COL will be about 2.990") H4198 71.0 grains, F215 primer, WW-Super brass (or Hornady or RP brass OK) 24-7/8" CZ barrel, 59*F 5-yard Oehler velocity, uncorrected to MV = 2550 fps
Starting with 55 grains of H4198 and 2.990" COL would probably be like a hot .45-70 Govt. load from the restrained .458 WinMag. You can play with low powder charge and +/- foam wad filler as well as COL to find an accurate load at desired velocity, I bet.
