Abstract: A cased telescoped ammunition with a perforated forward control tube in which the main propellant gas and flame front ignites a propellant surrounding the tube through the perforations. Seals form annular segments of consolidated propellant surrounding the tube separated from each other and the main propellant charge. These seals prevent gas and flame front propagation from the main or rearmost charge of propellant, except through the control tube perforations or ports which have been passed by the obturator.

Abstract: A low dispersion discarding sabot projectile comprising: a full caliber cylindrically shaped pusher having a cup-like forward facing recess concentric with the external surface of said pusher, a circumferential groove for receiving a rotation ring, said groove being positioned in approximate radial register with a rear surface of said recess, and a concave recess in the rear end face of said pusher; a cylindrically shaped subcaliber projectile having: (i) a rear portion adapted to be inserted into said forward facing recess of said pusher, (ii) a main body portion projecting forward from said pusher, and (iii) a nose portion; and a discarding sabot of lightweight frangible material disposed around said main body portion, the forward portion of said sabot being spaced radially away from the external surface of said nose portion.

Abstract: A method of manufacturing a spin stabilized discarding sabot projectile comprising the steps of preassembling a subcalibre cylindrical projectile in a full calibre cylindrical pusher, installing the subassembly in a two section injection molding machine with spring biased pusher locator and spring biased projectile nose locator for precisely holding the subassembly aligned with a primary axis, following which plastic material is injection molded about the projectile. Surplus plastic material may be removed as by machining and a noise piece may be added.
