when firing into the air, when it comes down its just at normal falling speed as its expended all its energy on the way up. wont hurt anymore than a pebble of equivalent weight falling on you.
Yeah. Common misconception that a bullet travels just as fast on the way down as on the way up.
Then again, 230 grains with a BC of about 1/4 at terminal velocity would still be unpleasant.
Most probably not deadly at all plus the human density is pretty low in comparison to free space even in densely habited areas.
Parabolic arcs (ie 45 degrees) are way more dangerous... and still the above applies.
So far managed to evade all deadly rain and hail.
