A telescoped ammunition round utilizing nonstrategic materials is light-weight and enables the use of conventional particulate propellants as well as conventional components such as projectiles and primers if desired. Webs molded into the case interior facilitate molding of the case and provide for supporting the projectile therein before and during the loading of particulate propellant into the case. In addition, the webs are operative for decreasing the longitudinal resistance of the case thereby reducing inward movement of the primer when struck by a firing pin thereby reducing the possibility of misfire. The projectile is prevented from debulleting during handling and is provided with preselected shot-start characteristics by an opening formed through the cap and a plurality of holes formed in the cap to provide proper resiliency in the cap for holding the projectile before firing and retarding the projectile momentarily upon firing.

A telescoped ammunition round comprising: (a) a projectile having a rear end surface generally transverse to the longitudinal axis of the projectile and an ogive; (b) particulate propellant; (c) a one piece substantially hollow case of plastic material in the form of a right circular cylinder having an interior side, an exterior side, and an open forward end; (d) a base formed in the rear end of the case; (e) a primer centrally mounted in said base, with the primer and base closing the rear end of the case; (f) said case having a plurality of integral internal structural webs formed therein of the same plastic material as the case, and extending longitudinally from the base to a position proximate the forward open end of the case; (g) such webs having portions which abut the interior side of the case from the base of the case to a position proximate the forward open end of the case, and further having portions which abut the rear end surface of the projectile, and such webs being shaped to support the projectile within the case in a coaxial position enabling the particulate propellant to be poured into the case and around the projectile through the case open end; (h) a separate plastic cap fitted to the case open end; (i) the cap having a cylindrical opening therethrough which is coaxially aligned with the projectile, and into which the forward end of the projectile extends; and (j) means located on said cap for engaging the ogive of the projectile for preventing premature forward movement of the projectile within the case.
