A propelling charge support comprises horseshoe-shaped clips for engaging the tail fin and holding the propelling charges together for protection, a rounded saddle for holding the propelling charges of the cartridge, and winged edges to protect the propelling charges and aid in removal of the propelling charge support from the tail fin. The propelling charge support further comprises a flat outer surface on which the propelling charge support loaded with propelling charges can rest while being installed onto the tail fin. It comprises a fin engagement clip that interfaces with a fin blade when installed on the cartridge, and that prevents rotation of the propelling charge support and propelling charges about the tail fin axis during rough handling and transportation, preventing damage to the propelling charges.

A protector for propelling charge increments on a mortar shell includes a semi-cylindrical body, the semi-cylindrical body arranged around a bottom and sides of the charge increments; two generally horseshoe shaped end plates attached to a front and a rear of the semi-cylindrical body, the end plates defining openings therein, the tail tube of the mortar fitting in the opening in each end plate, the charge increments being disposed between the two end plates; a wedge-shaped boom attached to the rear end plate, the wedge-shaped boom fitting between two fins on the fin portion of the mortar shell; a stop tab attached to a rear end of the wedge-shaped boom, the stop tab extending substantially perpendicular to a narrow side of the wedge-shaped boom to contact an end of the fin portion thereby minimizing longitudinal motion of the charge increments; and a nose cone attached at the front of the semi-cylindrical body, the nose cone defining an opening at its front end, the middle portion of the mortar shell fitting in the opening.

A container that is a spirally-wound, laminated, and cylindrically shaped is capable of protecting a mortar or other round from a large number of environmental conditions. The laminate material includes a layer of low-density polyethylene (LDPE) heat-bonded to a kraft paper, and is both durable, strong, and moisture-resistant. During the container manufacturing process, multiple layers of the laminate material, augmented by one or more layers of aluminum foil, are wound in a spiral fashion over an interior cylinder of ammunition container board, using conventional tooling and machinery. Layers of the cylinder are bonded to their contiguous neighbors by adhesive. The ends of the containers are sealed with crimped metal end caps, effecting a durable and moisture-resistance seal and giving the cylinder added crush-resistance. The construction of the container requires no high temperature operations, produces no noxious fumes, and does not expose workers to hazardous or toxic materials. In addition, there is less waste as compared to the current technology.
