I believe it was Newton who proved that two metal balls of differing weights,
dropped from the same height at the same time shall reach the ground at the
same time (discounting the negligible effects of friction through the air).
Similarly, if one ball was dropped, and at the same instant, another ball
was thrust horizontally from the same height, they would both reach the
ground at the same time (assuming a relatively flat earth).

Therefore, if you bore sighted a target, that would be suspended with some
mechanism that would release the target the instant you pulled the trigger,
you would always hit the target (assuming negligible effects of air friction
as the target dropped).
