ABSTRACT:
A hypodermic syringe projectile for animal usage characterized by a hollow housing which receives an axially movable body member. A chamber for receiving treatment liquid is defined between an end of the body member and an end of the housing which mounts an injection needle. The body member is retained in a fully retracted or filled position by flexible fingers on a wall thereof which selectively engage an end of the housing and which are maintained in such retained position by a weight. Movement of the weight upon impact with an animal releases the body member for movement from the retained position and forces the treatment liquid from the chamber through the injection needle.
