If I recall correctly the 442 uses a healed bullet like a 22 so likely requires specific dies for such (an assumption).
No first hand knowledge but I’ve seen ads posted that state 442 and/or 44 Russian so maybe they fit the chamber (?) and might be easier to load for.
One note on the 442; they were a black powder round (low pressure) and some guns in that era we’re made out of wrought iron, not steel, so do be careful with whatever load you put in it.
