摘要： A method for producing a gun barrel with an integrally adjoining housing for at least one breech head includes the steps of providing a cylindrical blank having a through-bore corresponding to the breech head diameter; hammering a first longitudinal portion of the blank on a part of a first hammering mandrel corresponding to the inner profile of the barrel while the first hammering mandrel is guided through the through-bore; and hammering a second longitudinal portion of the blank on a second hammering mandrel corresponding to the inner profile of the housing while the second hammering mandrel is inserted into the through-bore.

摘要： An improve firearm rifling is provided in which the trailing edge face of the land is significantly longer than the rifling land top surface. The trailing edge angle between the trailing edge face and the level of the groove floor surface is a much smaller angle than conventional rifling land trailing edge angle, while the leading edge angle of the disclosed embodiments may be akin to a conventional rifling leading edge angle. Due to this, the present embodiments provide a rifling land profile that is nonsymmetrical, with the trailing edge face being at a much lower angle than the leading edge face which is configured in a more upright orientation.
摘要翻译：提供了一种改进的枪支膛线，其中陆地的后缘面显着地长于膛ling台面。后缘面与沟槽底面的水平面之间的后缘角度比传统膛缘后缘角度小得多的角度，而所公开的实施例的前缘角度可能类似于传统的膛线前缘角度。因此，本实施例提供了一种不对称的膛线轮廓，其后缘面与被配置为更直立取向的前缘面成比较低的角度。

摘要： A jacketed bullet having a penetrator constructed of a hard material in line with a slug having a lower modulus. At least a portion of both the slug and the penetrator are then encased by a metal jacket. A plurality of circumferentially spaced and axially extending flutes are formed along the slug and possibly the penetrator. These flutes receive deformation of the jacket upon firing of the bullet into a rifled gun bore to thereby reduce friction between the bullet and the gun bore during operation.
摘要翻译：一种夹套子弹，具有由硬质材料构成的穿孔器，该硬质材料与具有较低模量的块状物一致。然后，两个塞子和穿透器的至少一部分被金属护套包住。沿着塞子和可能的穿透器形成多个周向间隔开并且轴向延伸的凹槽。这些凹槽在将子弹击中膛口枪孔时接收夹套的变形，从而在操作期间减小子弹与枪孔之间的摩擦。
