A case jacket made of a felted, in particular combustible fibrous material, comprising a cylindrical case jacket portion and a calotte-shaped case bottom which is connected to an end of the cylindrical case jacket portion, wherein the bottom-side end of the case jacket portion has a first inside diameter and a first outside diameter, and wherein the case bottom has an annular connecting edge towards the case jacket portion, which has a second inside diameter that is smaller than the first inside diameter, and a second outside diameter which is smaller than the second outside diameter, includes a conical connecting portion whose one end has the first inside diameter and the first outside diameter and is connected to the bottom-side end of the case jacket portion, and whose other end has the second inside diameter and the second outside diameter and is connected to the connecting edge of the case bottom, wherein the angle of inclination of the inner wall and the angle of inclination of the outer wall of the conical connecting portion with respect to the cylinder axis are not more than 10°.

The present invention relates to a granulated block propellant device for firearms that is comprised of a generally rectangular body that has a flat top surface and a flat bottom surface, in addition to a set and a second set of generally parallel side surfaces. In differing embodiments, the body may be in the form of an axial slab body, a radial disc body, or a concentric-wrapped body. The body is further comprised of at least one perforation that can be arranged in a plurality of configurations. The body may also be comprised of at least one partial cut on a surface of the body that does not have the plurality of configurations. In one embodiment, the device can be placed in the casing of a projectile and used as a propellant. Multiple devices may also be stacked atop one another within a projectile casing.

Small-, medium-, and large-caliber combustible cartridge cases and propellant combustible containers that are manufactured using reactive injection molding of azido polymers. An injection process for a single propellant combustible charge including the steps of: providing a quantity of azido bearing polymer; providing a quantity of curing agent; optionally providing a quantity of chemical blowing agent; optionally providing a quantity of fibers; optionally providing a quantity of additives and catalysts; and providing a mold defining a male cavity, a female cavity, and an injection port. The injection process further includes mixing together the azido bearing polymer, the curing agent, the optional chemical blowing agent, the optional fibers, the optional additives and catalysts, and injecting the resulting mixture into the mold.

The present invention is directed to a process for making combustible foam celluloid munition parts having high aspect ratios, different densities or having an insert embedded into the foam celluloid munition part. The process for making such foam celluloid munition part requires pre-soaking dry particles of celluloid, placing the celluloid particles into a munition part mold, exposing the celluloid particles to high heat and pressure until the celluloid particles expand and fuse into the shape of the mold. Varying the density or the size of the celluloid particles used in the process produces munition parts having different densities. In addition, the placement of inserts into the particles prior to exposure to high heat and pressure produces munition parts having inserts that are useful for identification and tracking of such parts.
