Power Pistol is fine for moderate loads in the 44 Mag, actually preferred over a slower powder for the reduced loads.

With 240gr plated bullets (Rainier or Xtreme) I've gotten good grouping using 9.5-10.0gr of P-P. MV @ ~1040-1090fps.

With 240gr JHPs (Zero & Nosler) 12.0gr was the highest I've run with P-P out of my 329PD (on a 13.5gr max.) & it also grouped the best.

Thank goodness we have many powders to choice from but if I was restricted to only one powder for everything I handload for, from 38 Special to 500 Mag, it'd be Power Pistol. I've got loads for them all.
