An improved small diameter, high density shaped charge perforating apparatus is provided. The perforating apparatus includes an elongated carrier member having a plurality of shaped charge receiving stations spirally located therealong. The anterior and dorsal sections of the shaped charges extend outside the outer diameter of the carrier member and a length of helically wound detonator cord passes through an axial aperture in the dorsal section to retain the shaped charges in the carrier member. An alignment member is connected to one end of the carrier member to prevent rotational movement of the carrier member within the gun body and aligns the axis of perforation for each shaped charge with spotfaces on recesses in the periphery of the gun body.
