AbstractMilitary 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.
