La respuesta básica es que todo lo que sube, baja, pero en este caso con mala leche
…the terminal velocity of your typical bullet coming back down varies a lot but is normally more than 200 feet per second.
And, other writers on the subject (there have been quite a few) say that tests on cadavers show that skin is punctured and underlying organs messed up (my words, not theirs) at bullet velocities that exceed 180 feet per second. And, since falling bullets typically strike people in the head or shoulders, this appears to me to be a very dangerous practice. [Notes from the Technology Underground]
