bullets fired into the air go to the ground.
where do bullets fired into the air go?
the ground
bullets fired into the air usually fall back with terminal velocities much lower than their muzzle velocity when they leave the barrel of a firearm. nevertheless, people can be injured, sometimes fatally, when bullets discharged into the air fall back down to the ground. bullets fired at angles less than vertical are more dangerous as the bullet maintains its angular ballistic trajectory and is far less likely to engage in tumbling motion; it therefore travels at speeds much higher than a bullet in free fall.

armor-piercing bullets for rifle and handgun cartridges are designed to penetrate ballistic armor and protective shields intended to stop or deflect conventional bullets. although bullet design is an important factor with regard to armor penetration, the ability of any given projectile to penetrate ballistic armor increases with increasing velocity. rifle cartridges typically discharge bullets at higher muzzle velocity than handgun cartridges due to larger propellant charge; but the same cartridge fired from a rifle will have a higher velocity because of the longer period of acceleration within the longer gun barrel, so bullets fired from rifles may be more capable of piercing armor than similar bullets fired from handguns. in addition, a small-caliber bullet has higher sectional density than a larger-caliber bullet of the same weight, and thus more capable of defeating body armor.
