Abstract
a cartridge case is assembled from three pieces, namely a cylindrical tube, a strengthening piece insertable in the tube, and a base ensheathing the end of the tube occupied by the strengthening piece, utilizing a strengthening piece fashioned in a substantially non-deformable material with a ready-made radially projecting flange; the base is open at both ends, and formed with stretches of dissimilar diameter interconnected by a flared reduction the internal surface of which creates a seating by which the flange can be accommodated together with one end of the tube, Having inserted the tube through the smaller diameter of the base a short way into the larger diameter stretch, the strengthening piece is inserted into the base from the opposite direction, located in the tube, and driven forward such that the end of the tube is splayed and sandwiched between the flange and the seating, whereupon it remains only to crimp the excess part of the larger diameter stretch inwards to lock the strengthening piece in place.
