The projectile brake has two brake shoes movable relative to one another. The brake shoe carriers engage with spring pressure on either side of a wedge which is movable transversely to the application and release directions of movement of the brake shoes. When the wedge moves, the two brake shoe carriers move in opposite directions to one another; the two shoes move over the same distance relative to one another so that the longitudinal axis of the braking channel is always in alignment with the path of the projectile entering from the guide channel despite wear of the brake linings.
