军用步枪子弹被假定在目标中翻滚180度，最终面朝后，但完好无损。然而，有人声称，德国版本的7.62毫米x51（7.62毫米北约）子弹可以在100米的距离内破碎。护套缺乏强度，导致其在以高冲击速度击中目标时在槽缝处断裂，这是造成这种行为的原因。丹麦武装部队使用的是7.62毫米x51的子弹，由Ambustionsarsenalet（AMA）生产，设计类似。鉴于1899年《海牙宣言》可能会对这种子弹和类似子弹的合法性提出质疑，我们决定对实际致命案件的调查进行补充，使用弹药明胶进行调查。为了在平等的基础上比较各种不同的子弹，它们以不同的射程射入弹药凝胶，从而以不同的撞击速度射入弹药凝胶。使用了美国政府、Bofors（瑞典）、Raufoss（挪威）和AMA制造的子弹。以前使用的AMA子弹M/75被发现在大约1000米的范围内碎裂。100米，对应的冲击速度约为。715米/秒，而所有其他3种类型的子弹在2.5米的范围内完好无损，对应的冲击速度约为2.5米/秒。810米/秒为了回应这一批评，AMA子弹的最终原型被证明能够承受碎片以及之前测试的外国制造。它将于1995年底开始批量生产。
Military rifle bullets are assumed to tumble 180 degrees in the target and end up facing backwards, but intact. It has been claimed, however, that a German version of the 7.62 mm x 51 (7.62 mm NATO) bullet may fragment at ranges up to 100 m. A lack of strength in the jacket, causing it to break at the cannelure when hitting the target at high impact velocity, has been held responsible for this behaviour. The Danish Armed Forces use a 7.62 mm x 51 bullet, produced by Ammunitionsarsenalet (AMA), which is similar in design. Since the legality of this and similar bullets may be questioned in view of the Hague Declaration of 1899, we decided to supplement an investigation of actual fatal cases with an investigation using ordnance gelatin. In order to compare various makes of bullets on an equal basis, they were fired into ordnance gelatin at various ranges and, consequently with various impact velocities. Bullets manufactured by the US Government, Bofors (Sweden), Raufoss (Norway) and AMA were used. The AMA bullet M/75 used previously was found to fragment at ranges up to approx. 100 m, corresponding to impact velocities of approx. 715 m/sec, while all the other 3 types of bullets were intact at ranges down to 2.5 m, corresponding to impact velocities of approx. 810 m/sec. The final prototype of an AMA bullet to answer this criticism proved capable of withstanding fragmentation as well as the foreign makes previously tested. It will enter series production in late 1995.
