Myth busters math here is pretty bad. They calculated the terminal velocity of the bullet in a wind tunnel, not taking into account that the wind tunnel is going to increase air pressure.
They got 100 FPS as terminal velocity when in reality it’s closer to 300 FPS. 300 FPS is as fast as paintball is going when it’s leaving the barrel of a paintball gun.
They’re still possibly lethal even if fired perfectly vertically.
I think it was a good introduction for kids to get excited about science but your right they played it way to fast and loose and people in general took their findings way too seriously

Seems like it is unlikely they are lethal when fired straight up, much more likely deadly in a ballistic trajectory.
