I would like to request some reference on the use of Uranium in the casing of a shell or round. The casing gets thrown out on the ground (by both aircraft and tanks) when the round goes off. There is no reason to use anything other than brass or steel for this.

There is some confusion in terminology here. The brass case is indeed discarded when the round is fired. Byt 'casing' he means the exterior of the warhead. The word 'round' is used for both the warhead+gunpowder+brass and then for the warhead itself. Larger artillery pieces do not use a brass shell case at all. The round is loaded, and then the powder is rammed in after it.

I can find no reference any U-core round being HE or otherwise carrying a charge. In all cases that I am aware of and can find reference to it is simply a KE attack on the target where the by products of the impact bounce around inside the target grinding up whatever is in there.

I believe that this is true, except that the 'products of the impact' are drops of metal and what they do is worse than grinding something up. -- Jim Dixon
