Abstract: A mechanical shooting apparatus is disclosed, the apparatus having an elongate body comprised of two connectedly displaceable body members, the first body member having a pair of opposed pulleys adjacent its rearward end and another pair adjacent its forward end, and further including an elongate track portion on its upper surface. A loop member having a linearly resilient segment is seated against the second body member's forward end, opposing lengths of the loop extending rearwardly around the rearward pulleys, and forwardly around the forward pulleys, a sliding dog being attached to the loop between the forward pulleys and being slidably engaged with the track portion A trigger for holding the sliding dog rearwardly when drawn from between the pulleys, and for suddenly releasing the dog, is provided. A velocity increasing mechanism replacing the sliding dog is also disclosed, the mechanism comprising a ferrule affixed to the loop between the forward pulleys.
