Firing directly straight up will rob the bullet of it's velocity even though it will be still be rotating at many tens of thousands of RPMs when it comes back down.

A bullet fired at a 45-degree angle will certainly be lethal. I've seen a hole in a fender of a truck caused by celebratory shooting that came down at about a 60 degree angle. It was a .30 rifle round of some kind and was probably fired from well over a mile away.

“rotating at many tens of thousands of RPMs when it comes back down”. sure about that?
