So powerful that it is illegal under the Geneva Convention to shoot this at ground troops unless over a certain distance. (Sniper applications). The world record for one man killed is 1,800 metres, by an elite sniper squad, with access to a .50cal, GPS, laser rangefinders, etc. They still needed multiple shots to hit their target.
Still, leaves an exit wound the size of Canada.
Oh and this is much more powerful than a .50AE round, they are NOT the same.
Do NOT get shot by this.
