It will make a small stain on the victim's clothes or chest, but it will ultimately not make a blood puddle. The second shot stops the beating of the heart, as two bullets have torn the organ to shreds, thus making no more profuse production of blood as it pulsates from the wound, and the horizontal angle the body has as it lies on the floor will not make sitting blood flow out. So you can take the body and hide it without cleaning up any blood it could have left behind with only one bullet inside of it.
