Tim -

Have you ever seen a softball sized hail that falls - smashes roofs to
junk
and puts deep bends in cars.

Then there is the smaller stuff that are golf ball size that knocks out
people
left and right.

I suspect you are talking about pea size or rice size. Yea - that is
almost like snow.

I think you will find that softball size and probably golf
ball size hail often has much more energy than the terminal
velocity of a falling rifle bullet. By the way, nobody
mentioned pistol bullets. Although they often weight more
than rifle bullets, pistol are much less aerodynamic than
rifle bullets and would not achieve as high a terminal
velocity and would cause less damage than a pointed rifle
bullet.


It would be hard to tell, because a rifle bullet is not going to be spin
stableized any more. It would start falling base to earth until the wind
resistance hitting the flat base would start it tumbling. Now if the bullet
shape had the center of gravity foward of the tip to base center point, then
it would fall stable pointy end down and have a very high terminal velocity

Why wouldnt it be spin stablized? Granted there are some rotational
friction forces (skin layer) slowing it down, including air pressure
against the meplat and base going up and down..but give rotational
speeds of the common bullet are in excess of 100,000 rpm...... it
would take a lot to slow it down.

I think it dates from when we started looking at virtues
as funny. It's embarrassing to speak of honor, integrity,
bravery, patriotism, 'doing the right thing', charity,
fairness. You have Seinfeld making cowardice an acceptable
choice; our politicians changing positions of honor with
every poll; we laugh at servicemen and patriotic fervor; we
accept corruption in our police and bias in our judges; we
kill our children, and wonder why they have no respect for
Life. We deny children their childhood and innocence- and
then we denigrate being a Man, as opposed to a 'person'. We
*assume* that anyone with a weapon will use it against his
fellowman- if only he has the chance. Nah; in our agitation
to keep the State out of the church business, we've
destroyed our value system and replaced it with *nothing*.
