Useful clips, thank you Pa. Yes, as you point out, loading with a 20 round clip from the right side is the correct way of loading this somewhat awkward weapon. So in the Strelets master shown here, the right hand side of the gun should have a definite magazine; and the loader/Number 2 needs to re-position himself to load from the other side of the gun.
I seem to remember reading somewhere that an Italian infantry squad was unable to sustain the rate of fire of, say, a comparable German unit...and one reason was the Breda Modello 30 and its design problems.
