Art,
You have two waves going in your argument: electromagnetic waves in free space (i.e. a vacuum with no material present); and longitudinal waves propagating in a physical medium.
The EM waves can go a long ways, but the pressure waves attenuate and disappear very quickly.
Ulf's paper emphasizes that the bullet damage is only due to the physical passage of the bullet.
In any case you need to shoot the bullet into the animal in a place where the damage kills quickly. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
