Tantalum would be an _excellent_ material for shaped charges, indeed.
It is about the most ductile of the metals, very dense (almost as
dense as uranium), inert like platinum (won't combust on hitting
something), high melting (about 3000 oC, a great advantage). Tungsten
is also very good for shaped charges, at least it gives a few tens of
per cent increase in performance compared to copper. I am quite sure
tantalum would outperform it.
