Which mechanics? Bullets that aren't discharged straight up - or nearly
straight up (TCM said 45 degrees, I think steeper than that may be
required) aren't truly falling, as they have not expended their initial
A bullet freefalls at around 120 mph, same as humans - I know a parachutist
who stepped out with a .45, a .38 and a .223 bullet, released them after
getting stable and watched them match his rate of descent, until he popped
his 'chute. That's 176 fps, a 90 mph baseball is 132 fps, just for
comparison. That's LESS than wrist rocket velocities.
Hence, such people aren't hit by "falling bullets" - they are shot as a
result of a negligent discharge. The bullet may described a very high arc,
but it's still a ballistic trajectory.
[ Conservation of momentum requires that irrespective of the angle of
incidence the bullet may have when it leaves the barrel, that it will
have that same amount minus frictional effects when it comes down.
The bullets drop at roughly the same rate because gravity is constant
and the resistance to air flow is aout equal for all bodies. It is
not comparable in any realistic way as an example of bullet dynamics
after being thrown out a barrel at several thousand feet-per-second.
The difference in air density along the flight patch is significant
with respect to friction between a vertical and a horizontal flight
so those factors must be added as well. Also, especialy in urban
areas low grazing shots are more likely to hit a building or other
generaly vertical surface. Rounds fired more vertical however tend
to plunge, that implies they hit roofs. I would suspect a bullet
would retain more energy in a vertical path than a horizontal one.
I don't think that difference would come anywhere to approaching
an order of magnitude however. ]
