Good advice, Grayfox.
Though if you are willing to accept a notable compromise with one or both cartridges, a single powder may be do-able for these cartridges. Two powders come to mind with H4895 being my favorite & Accurate 2520 being my second consideration. Two rather flexible propellants that can be ideal in some instances & work rather well in others.
Reality may take you back to Grayfox's advice as Accuracy & upper velocity may be found with diffrent propellants for each cartridge.
