The SHELL, H.E., M43 was originally adapted as the light shell for the 81-mm mortar. It is designed for use against light targets such as machine gun nests, barbed wire entanglements and personnel in the open.

Shell body. The body of this shell is constructed of forged steel. It is tear-dropped in shape; that is, blunt nose and tapered tail. It has a bourrelet machined near the nose of the shell consisting of several annular grooves which serves to act as a forward bearing surface and a gas check. The action of the propelling charge gasses expanding in the grooves and contracting to pass the raised portions tends to slow the gasses and prevent their passing the bourrelet. The nose is machined and threaded to receive an adapter. The adapter is threaded and acts as a bushing for bakelite fuse well cup and the fuse. The bakelite fuse well cup is fitted to the adapter before it is assembled to the shell body and prevents the entrance of foreign material into the fuse cavity prior to the assembly of the fuse to the round. The fuse used is the Point-detonating Fuse M45. This fuse has a selective element and can be set for either super quick or delay action. To the rear of the bourrelet is a curved taper reducing the base of the shell to approximately 1 1/Z inches. The base is closed and machined so as to receive a stabilizer assembly. The shell filler is 1.22 pounds of TNT. The total weight of the completely assembled round is 7.05 pounds. Entire length of the fused shell is 13 1/4 inches.

The fin assembly consists of a machined cartridge container to which six stationary fins are attached. One end is closed and threaded so as to be screwed on to the body of the shell. The other end is machined and hollow inside so as to receive the ignition cartridge. Several holes leading from the interior to the exterior periphery of the cartridge container serve to conduct the flames from the ignition cartridge to the propellant increments which are seated in the fins.
