A hit-scoring target for shooting practice having several mutually bonded layers, a first layer at least the outside surface of which is electrically conductive, a second, electrically nonconductive, at least semi-rigid layer imparting mechanical strength to the first layer and made of a material tolerant of the heat of a freshly fired projectile, a third, electrically nonconductive layer made of an elastically resilient material, a fourth layer of which at least the surface contacting the third layer is electrically conductive, and a fifth layer serving as a backing and imparting relative rigidity to said target. The distance between the electrically conductive surfaces of the first and the fourth layer is smaller than the length of the shortest projectile to be fired at the target, whereby a projectile hitting, penetrating and passing through the target causes a transient electrical low-resistance connection to be established between the electrically conductive surfaces. |
