A telescoped ammunition round comprises: a propellant charge having an axial cavity for supplying firing power for the ammunition round; a projectile housed within the axial cavity for being fired from a forward end of the ammunition round; a control tube means housed within the axial cavity for selectively covering an aft surface portion of the propellant charge axial cavity, the control tube means having a generally cylindrical axial bore substantially coaxial with the axial cavity, the projectile extending forward of the control tube means; coupling means for releasably securing the projectile to the control tube means; a control tube pistion having a generally cylindrical outer shape forming a sliding fit within the axial bore, positioned aft of the projectile; a booster charge within the axial bore, the control tube piston being forwardly movable in response to the firing of the booster charge and the projectile, in turn, being forwardly movable by forward movement of the control tube piston; a primer means in communication with the booster charge for actuating a firing sequence for the ammunition round; and projectile guide means for guiding the projectile during forward movement thereof from the axial cavity to a gun barrel upon firing the ammunition round, comprising a generally circular disk mounted in a forward position within the ammunition round substantially normal to the longitudinal axis thereof and concentric with the projectile, the disk comprising segmenting means for segmenting the disk into a plurality of generally triangular petals resiliently forwardly deflectable from the center of the disk to apply radially centering pressure upon the projectile during forward movement thereof.

A telescoped ammunition round comprising: a propellant charge having an axial cavity for supplying firing power for said ammunition round; a generally tubular casing means surrounding said propellant charge; a full caliber projectile housed within said axial cavity for being fired from a forward end of said ammunition round; a control tube means housed within said axial cavity for selectively covering an aft surface portion of said propellant charge axial cavity, said control tube means having a generally cylindrical axial bore substantially coaxial with said axial cavity, said projectile extending from within said axial bore to forward of said control tube means; coupling means for releasably securing said projectile to said control tube means; a control tube piston having a generally cylindrical outer shape forming a sliding fit within said axial bore aft of said projectile; a booster charge withins aid axial bore, said control tube piston being forwardly movable in response to the firing of said booster charge and said projectile being forwardly movable by forward movement of said control tube piston; a primer means in communication with said booster charge for actuating a firing sequence for said ammunition round; and one-piece projectile guide means for guiding said projectile during forward movement of the projectile upon firing said booster charge, comprising a generally circular disk mounted in a forward position within said ammunition round and anchored to the tubular casing means substantially normal to the longitudinal axis of the projectile and concentric with said projectile, said disk comprising segmenting means for segmenting said disk into a plurality of generally triangular petals resiliently forwardly deflectable from the center of said disk to apply radially centering pressure upon said projectile during forward movement thereof during firing of said booster charge; whereby the disk remains anchored to the tubular casing means as the projectile is ejected from said ammunition round.
