A shell possessing a substantially cylindrical shell casing in which there is contained an explosive mass and at the inner wall of which casing there bears a layer of substantially spherical-shaped projectiles of the same size which are partially embedded in the explosive mass and between which there is locacted a filler mass. The projectiles which are partially embedded in the filler mass are exposed to axial pressure in the finished fabricated shell in order to avoid displacement and detachment of the projectiles from the shell casing and the thereby resulting imbalance during firing of the shell. The method of fabricating such shell contemplates inserting a guide sleeve into the shell casing and between the shell casing and the guide sleeve there are embedded equal size spherical-shaped projectiles. The projectiles after being filled into the shell are exposed to pressure in the axial direction and thereafter the guide sleeve is removed. A filler mass is filled into the shell casing while the same rotates for such length of time until the projectiles are partially embedded in such filler mass and an explosive mass is filled in a liquid state into the shell casing so that the projectiles have the remaining portions thereof embedded in the explosive mass.
