A projectile adapted to be propelled at sub-sonic speeds to carry a dose of medicament or an electronic device into an animal while causing minimum physical damage to the animal's hide or flesh. The projectile has an average density of less than about 5 grams per cubic centimeter, an elongate body portion adapted for close fitting engagement in a barrel from which the projectile is propelled, and a conical nose portion having a radiused apex. A method of implanting a medicament or device in the flesh of an animal. The medicament or device is combined in the projectile and the projectile is propelled nose first at sub-sonic speed from a range of one to sixty feet through the hide of the animal so that the nose portion causes only a slit in the hide of the animal, which is shorter than the diameter of the projectile, and so that the projectile makes only limited penetration of the flesh.
