Agreed, the two things that make a bullet effective is mass( weight), and speed. If you take away the speed, the bullet will have the same mass but the lack of speed upon impact, the same weight bullet in a both a sonic and a subsonic round will be less effective upon impact in a subsonic round . In addition the slower the bullet travels the faster it loses speed on it's way to the target.
