A spotting projectile, especially for training purposes, which dispenses a cloud of powder upwardly on impact to indicate its location visibly. The projectile has an interior cylinder receiving a piston in gas-sealing slidable relation, so that gas trapped in the cylinder is compressed by forward inertial movement of the piston when the projectile impacts. The compressed gas ejects a powder charge carried by the piston rearwardly from the projectile to form a visible cloud.
A spotting projectile comprising: a casing having a longitudinally-extending interior passage terminating rearwardly in an exterior opening and terminating forwardly in a wall-forming casing portion; piston means mounted in said passage for sliding motion longitudinally therein, said passage, piston means, and wall-forming portion defining a gas-sealing expansible chamber therebetween; said piston means initially being located rearwardly in said passage and being inertially slidable forwardly therein upon impact and deceleration of the projectile, to com...
