An improved automatic pellet carrier (100) fed pellet implanting gun apparatus (10) is described. The carrier is mounted in an opening (12b) through a front side (12c) of a retractable head (121 which is linearly moveable in a nose end (11c) of a handle assembly (11) along a longitudinal axis a-a. The carrier relies upon an internal spring (107) to automatically register a pellet (101) in a bore (12a) in the retractable head so that by actuating a trigger (14), a drive rod (23) which travels linearly along the axis a-a and through the bore in the retractable head and through the carrier, can move the pellet into the barrel (13a) of a needle (13) that has been inserted into an animal or the like. After the pellet enters the needle, the needle, the retractable head and the carrier are mechanically retracted into the gun with the carrier retracting along a slot (11f) in the nose so that the pellet is deposited in the animal, unobstructed by the needle. Releasing the trigger causes the retractable head, the needle and the carrier to return to their rest positions in the nose of the gun and the drive rod to move out of the bore in the retractable head and into the handle assembly so that the internal spring in the carrier can automatically register the next pellet in the carrier into the bore in the retractable head of the gun apparatus.
