Just my humble opinon.... I
wonder if the US has really stopped using depleted uranium, or if they've found
something almost as good?



Just about any really dense metal will do for this type of technology, I've seen rounds
made with hardened copper that work quite well. The big problem is finding something that
is really dense that has sufficient tensile strength to withstand the acceleration of being
fired from the weapon and at the same time is not expensive. DU filled these requirements
nicely, it's a waste product and thus cheap, as an added boon this was a great way of disposing
of several thousands of tons of unwanted radioactive waste. I believe I read that making
this type of kinetic round with copper is actually more expensive than DU.
