There is an interesting article by Roy Ruel on revolver
recoil in the winter, 1986 issue of Handgun Illustrated.
The author states that for a given revolver, the point
of impact is the same for all bullets of the same weight
regardless of velocity. Heavier bullets strike higher and
lighter bullets strike lower because of muzzle rise during
recoil. Higher velocity requires more force but this is
cancelled out because it acts on the bullet in the barrel
for a shorter duration. Higher velocity does result in
less drop due to gravity during the bullet's travel to the
target, but this is insignificant at handgun ranges.
Does anyone want to comment on this, based on either theoretical
or empirical considerations?

Article: 1:4 References: <1957@jade.BERKELEY.EDU> 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).
