Depends on the range you need it to work at. For accuracy it is necessary to avoid transonic velocities as this can destabilise the bullet. Start it out subsonic and this is not an issue assuming that you can get the desired range - say 700 - 800 fps. If you need more range then you need to go well supersonic so that it is still supersonic all the way to the target. .44 mag will never be good at ranges above around 300 yards because of this, and never was it expected to - it is after all a pistol calibre.
