As far as I can recall, uranium has this nifty property of being self-sharpening (as it go's through the air it keeps a nasty point).
Here is some info on it:
"To understand why DU makes a good anti-tank weapon you have to enter the Alice In Wonderland world of high-energy collisions. When metal meets metal at five times the speed of sound, hardened steel shatters like glass. Metal flows like putty, or simply vaporises. A faster shell does not necessarily go through more armour, but, like a pebble thrown into a pond, it makes a bigger splash.
Armour penetration is increased by concentrating the force of a shell into as small an area as possible, so the projectiles tend to look like giant darts. The denser the projectile, the harder the impact for a given size. DU is almost twice as dense as lead, making it highly suitable. The other metal used for anti-tank rounds is tungsten, which is also very hard and dense. When a tungsten rod strikes armour, it deforms and mushrooms, making it progressively blunter. Uranium is "pyrophoric": at the point of impact it burns away into vapour, so the projectile stays sharp. When it breaks through, the burning DU turns the inside of a vehicle into an inferno of white-hot gas and sparks."
Reuters Responds to Allegations Regarding Videotape from East Jerusalem, 11 September 2001.
Reuters rejects as utterly baseless an allegation being circulated by e-mail and the internet claiming that it circulated 10-year-old videotape to illustrate Palestinians celebrating in the wake of the September 11 tragedies in the United States.
It also dismisses as completely unfounded later suggestions that its cameraman instigated or in any way encouraged the demonstration.
The videotape in question was shot in East Jerusalem by Reuters on September 11 in the immediate aftermath of the attacks on the United States. The footage was broadcast by CNN and other subscribers to the Reuters video news service.
Reuters is not in the business of falsifying the news. The public demonstration of support for the attacks was already under way when our cameraman and other media arrived on the scene.
Reuters welcomes the following statement by the Universidad Estatal de Campinas-Brasil (UNICAMP), one of whose students was the author of the original e-mail questioning the authenticity of the footage, setting the record straight
UNICAMP would like to announce that it has no knowledge of a videotape from 1991, whose images supposedly aired on CNN showing Palestinians celebrating the terrorist attacks in the U.S. The tape was supposedly from 1991, and there were rumors that the images were passed off as current.
This information was later denied, as soon as it proved false, by Márcio A. V. Carvalho, a student at UNICAMP. He approached the administration on the 17.09.2001 to clarify the following:
the information he got, verbally, was that a professor from another institution (not from UNICAMP) had the tape;
he sent the information to a discussion group email list;
many people from this list were interested in the subject and requested more details;
he again contacted the person who first gave him the information and the person denied having the tape;
the student immediately sent out a note clarifying what happened to the people from his email list.
The original message, however, was distributed all over the world, often with many distortions, including a falsified by-line article from the student. He affirms that a hacker attacked his domain. Several E-mails have been sent on his behalf and those dating from 15.09.2001 should be ignored.
Among the distortions is the fact that UNICAMP would be analyzing the tape, which is absolutely false. The administration considers this alert definitive and will be careful to avoid new rumors.
