7x43mm, a fascinating video from the 1950's

Interesting video ovenpaa, i got to photograph and handle the EM2 in the Royal Armouries Pattern Room collection a few years ago.
There was also a 7.62 version which was developed by the Enfield design time.

Killed off by the Americans who were pushing the 7.62x51. Now they've got 6.8SPC which is very similar to the 7mm or 280 British!

From Wiki http://en.wikipedia.org/wiki/.280_British

The .280 British concept would later prove to have been far ahead of its time, as the U.S. itself adopted an intermediate cartridge — 5.56×45mm NATO — by the end of the following decade. Soon after America's large-scale involvement in Vietnam commenced in 1965 the 5.56 mm ArmaLite AR-15 rifle, later standardised as the M16, was purchased in ever increasing numbers and by the late 1960s had displaced the 7.62 mm M14 in combat units. After insisting on a .30 caliber round with full-power ballistics almost identical to those of the existing .30-06, the U.S. then adopted the 5.56 mm intermediate cartridge, which demonstrated the emergence and dominance of intermediate cartridges on the battlefield (the other notable one being the 7.62×39mm AK-47 round). The adoption of the 7.62×51mm NATO round and the adaptation of the intermediate cartridge CETME (later developed into the G3) and FN FAL designs to fire it, produced rifles that were relatively longer and heavier and had greater recoil. The result was weapons that performed well as longer-range semi-automatic rifles, but were more cumbersome and only marginally controllable in automatic fire. These guns also had a higher training burden and were not well suited to soldiers of smaller stature, again due to the recoil. Coincidentally, in 2002 the Americans developed a military caliber intended for the M4 version of the M16 family called the 6.8 mm Remington SPC — with similar ballistic properties to the .280 British cartridge — which was intended to provide better ballistics than the 5.56×45mm.

Closest I got was some late night Robotic work just before one of the production lines went live, they were using the Yaskawa/Motoman L10 robots for some of the processes and were having huge problems. I was very familiar with the L10 so the Technical Director of British Federal (Spot welders) rang me up late one evening in a panic needing some help. Turns out I knew more about the L10 than they did

Anyway everything was easily sorted and the SA80 production started up on time.
