Interesting, thanks for the link. Intuitively it still seems like much of the energy from the projectile would be absorbed deep in the Earth as it traveled through. For sure it would cause some damage, but it still seems like a nuclear bomb would have a higher effective energy, as far as the tactical goal of taking out a city or something.
