Do you know what is the maximum speed that can be reached by an arrow shot with a bow?
Well, a bow shoots really fast, but a crossbow shoots TREMENDOUS fast!
That's it.
In fact, a good bow can shoot an arrow at a speed of 340 FPS (frames per second).
But a crossbow can hunt down a bear! 440 FPS is enough? That's the speed that a good crossbow can shoot at.
These videos are impressive!
