Abstract: A tracer training bullet which can be assembled into a conventional cartre case and fired in a conventional M2 machine gun is disclosed. The bullet consists of a main body of relatively low strength material which is segmented so that, if not restrained, it will bend under the centrifugal rotational force imparted to the segments by the spinning action of the projectile when fired. The bending of the projectile segments away from their central axis is ordinarily prevented by a retainer in the form of a spider. The spider is made of a relatively low temperature melting material, preferably aluminum, having a given thermal mass. The burn of the tracer material during the flight of the bullet toward a target weakens the retainer to the point of rupture after the bullet has travelled a given distance toward a target position. After the target position is passed, the securement member is destroyed by the high temperature burning action and the segments of the projectile bend or flex apart.
