Saurdaukar: Interesting stuff. Dont see how it can be 'legal' for combat usage though. Regular 5.56 ammo fragments into dozens of pieces at velocities above 2600fps - at distances below approximately 200 yards if shot from a 20-inch barrel. It leaves devastating wounds that are very hard or impossible to treat.
There is nothing illegal about US using any kind of bullets because it was never a party to any conventions limiting the bullet design.

http://www.ammo-oracle.comOctavius: That article doesn't reveal that much scientific data. I'd like to see an explanation for this: While I am not familiar with this praticular round, I can explain how the standard round works. I believe the mechanism must be similar.
You see, the shape of a military bullet makes it aerodynamically unstable - it tends to turn rear-end forward in flight. The proper sping of a bullet counteracts that tendency in air.
As soon as the bullet enters some denser tissue, the spin is not sufficient to keep it stabilised and it flips over. If the speed is sufficient, at about 3-4 inches deep in human flesh when it is travelling sidewise, the stress becomes too great and it breaks appart into two pieces that further disintegrate.
Easy disintegration is helped by weak thin copper jacket, canellure and internal bullet design.
So a bullet can easily be able to penetrate 1/4 inches of steel but desintegrate within 5 inches of tissue or a drywall.
Hunting bullets are usually round-nosed and they have much less tendency to flip over. Also, the bullets with copper-washed steel jacket or without canellure may not fragment as readily as the standard mill-spec rounds.
GtoRA2: That part is out dated I think and we should use the best ammo we can for our troops. At some point the bad guys will start using the same ammo that we do instead of clean prenetrating AK-47 rounds. At that point our statistics of 1 dead per 100 wounded will get much worse.
