Its Origin

The 5.56×45 ammo is a product of extensive research. During the 1950s, the need to modify ammunition arose in NATO and the 7.62x51mm was adopted. However, many criticisms had been trailing this ammunition prior to its adoption for use by NATO forces. Some of the criticisms lingered on after the adoption and usage. That ammunition was deemed to be too powerful and therefore not suitable for lightweight service rifles because of its tendency for excessive recoil. As a result, it was unable to provide enough automatic rate of fire from hand-held weapons used in modern combat operations.

At the same time, the British were experimenting their own class of intermediate cartridges and were almost adopting the .280 inch cartridge when the 7.62x51mm was adopted by NATO. The Belgian gun manufacturer, FN Herstal was also developing their version of the .280 inch. Rather than completely jettison the 7.62x51mm because of concerns for recoil, NATO opined that standardization of the ammunition was far preferred to selecting a perfect one. The US had gone ahead with more research even after NATO had adopted the other ammunition as a standard. That study led to the emergence of the 5.56x45mm ammunition. By the time the research results showed that the 5.56x45mm was more effective than the previous ammunition, there was little or nothing fighting forces could do than to adopt it for use. Though the original study and its subsequent adoption as ammunition of choice happened in the United States, NATO and many other countries have found the need to take on and use this very effective bullet.

From the 1950 through the Years

The 5.56x45mm ammo, alongside the M16 rifle was adopted by the US infantry forces. This was a temporary reprieve from the weight issues that characterized the 7.62x51mm. The general acceptance of the ammunition by the US and NATO in the 1950s through to the 60s made the ammunition more popular until it became one of the most popular centerfire cartridges in the world. This ammunition is renowned for its speed. At the initial stage, it was loaded with full metal jacket bullets that exited the barrel of the AR 15 rifle at more than 3200 feet in one second. In 1977, NATO formalized the adoption process of the 5.56×45 ammo by signing an agreement among its members to take on a smaller caliber cartridge,

By this act, NATO inspired a new preference for lightweight, small-sized military cartridges which were capable of providing low bolt thrust and free recoil impulse. Other countries like Russia in 1974 and China in 1987 developed their own versions of the 5.56x45mm for use by their military.

Despite all the criticisms that have been leveled against the performance of the 5.56×45 ammo, huge progress has been made in an attempt to bring it up to speed with trends per time and keep it continually relevant. For instance, the US military replaced the lead slug with a copper alloy slug, principally to cut down on the effect of lead on the environment. This has made the ammunition even more lethal in terms of penetration, accuracy and consistency in wounding ability. This was made possible by the M855 steel penetrator tip that was used to cap the ammunition to boost its effectiveness against targets. As common with military ammunition and rifles, there is always an opportunity for improvement of weapons. The 5.56×45 ammo has been criticized for lacking stopping power and totally depending on velocity for its effectiveness, however, the research teams around the world have worked on variations and modifications to this ammunition to make it capable of performing at the level of impact which the users would like it to.
