摘要： A training cartridge has a plastic projectile or plastic dummy projectile wherein the projectile or dummy projectile is integrally molded on a synthetic resin sleeve open at the rear end. The sleeve is inserted in a cartridge case of metal open at its front end. The cartridge case with case shoulder and case neck formed thereon is made to be open also at the rear end so that the synthetic resin sleeve can be inserted from the rear end into the cartridge case in close contact with the inner wall thereof. A separate metallic bottom piece is inserted into the rear end of the cartridge case, sealing the case tightly toward the rear.

摘要： A training cartridge has a synthetic resin projectile or dummy projectile wherein the projectile or dummy projectile is integrally molded to a synthetic resin sleeve or tube open at the rear end. The sleeve is inserted from the front end of a cartridge case of metal that is open at its front end. The sleeve is held within the cartridge case by drawing the cartridge case inwards, after insertion of the synthetic resin sleeve, in its frontal zone to form a conical case shoulder and a cylindrical case neck, which shoulder and neck encompass the synthetic resin sleeve in firm contact therewith. This arrangement achieves clean separation of the projectile from the remainder of the synthetic resin sleeve and/or avoids uncontrolled tearing off of parts of the synthetic resin sleeve.
摘要翻译：训练筒具有合成树脂射弹或虚拟射弹，其中抛射体或虚拟射弹一体地模制在合成树脂套筒或后端开口的管上。套筒从其前端开口的金属盒壳体的前端插入。套筒通过将合成树脂套筒插入其正面区域之后将盒体向内拉，从而形成圆锥形壳体肩部和圆柱形壳体颈部，其中肩部和颈部包围合成树脂套筒与其接触。这种布置实现了抛射体与合成树脂套筒的其余部分的清洁分离和/或避免了合成树脂套筒的部分的不受控制的撕裂。

摘要： A projectile, especially for hand firearms and automatic pistols, including a core member formed of a first material and provided with a blind bore extending in the forward direction into an outwardly inclined truncated cone surface indentation in the core member. A projectile insert member formed of a second material which is more difficult to deform than the first material, contacts the core member along the outwardly inclined truncated cone surface thereof and is provided with a lug portion extending into said blind bore of the core member for detachably joining said insert member and said core member. A jacket member encompasses the rear portion of said core member and extends forwardly at least up to a zone of the core member surrounding said blind bore. The jacket member has a front edge portion which terminates at a spacing from the forward edge portion of the core member so as to provide an unjacketed strip portion of the core member thereat.
摘要翻译：一种射弹，特别是用于手枪和自动手枪，包括由第一材料形成并具有沿向前延伸的盲孔的芯构件，形成在芯构件中的向外倾斜的截锥形凹面。由比第一材料更难变形的第二材料形成的弹射插入件沿其向外倾斜的截头圆锥表面接触芯构件，并且设置有延伸到芯构件的盲孔中的可分离的凸耳部分连接所述插入件和所述芯件。护套构件包括所述芯构件的后部，并且至少向上延伸至围绕所述盲孔的芯构件的区域。护套构件具有前端部，其以与芯构件的前边缘部分间隔的方式终止，以便在其中提供芯构件的未被覆盖的条带部分。

摘要： A projectile, especially for hand and long firearms, including a projectile body having a longitudinal axis, a front face and a rear face, a deformation cavity extends partially into the projectile body at the front face thereof and a continuous axial bore is provided in the projectile body in communicating relationship with the rear face and the deformation cavity. The projectile body has a wall thickness in the region surrounding the deformation cavity which is smaller than the wall thickness in the region surrounding the axial bore. A cap is initially disposed in the region of the front face of the projectile body for covering at least the deformation cavity, the cap being separated from the projectile body within the barrel of the firearm during firing of the projectile and exiting from the barrel in front of the projectile body.
