Twice as long - twice as good?

OK, this is a video about slingshot crossbows... nothing more, nothing less :)

One of the most powerful slingshot crossbows ever presented here at The Slingshot Channel is the winch operated hand cannon. It can handle much stronger rubber than any conventional slingshot. But it has an active draw length of only about 75 cm!

The speed (and energy) of a 25 mm steel ball fired from the weapon is an impressibe 45 m/s, about 68 Joules of energy. But then the "barrel" is doubled, giving the weapon a total acceleration length of 165 cm.

This leads to a speed of 69 m/s, increasing the energy of the 25mm steel ball to about 162 Joules - 2,4 times more!

As a bonus, a new two shot bullpup crossbow is shown. It fires two full size arrows, either at the same time or in consecutive order. Outfitted with a surplus G36 scope, it is really accurate and powerful enough to penetrate a car.

A "The Slingshot Channel" production!
