Yup. I don't know if you get this show over there, but on
"Mythbusters", they did a show on Hollywood myths, and this was one they
covered.
Momentum = mass x velocity. If we take a 150 pound man, and a 1 ounce
bullet, he has 2400 times the mass of the bullet, so if all the momentum
of the shot were transfered to the person, they'd be kicked back at a
velocity of 1/2400 of the bullet's velocity, tops.
If the bullet were going just under the speed of sound, that would give
the person a kick of around 1/3 of a mile/hour.
The Mythbusters did some tests shooting a dead pig. It was on a rig
that held it, but would let it fly back. The best they got, with a big
gun, was to knock it back a few inches.
