Seems a little overkill for hunting, that rifle! I can, however, see this being pretty fucking amazing in real life. Input rifle values such as bullet speed and let the computer calculate elevation, angle, etc. and then attach the computer to a little antenna type thing with one of those wind-speed gauge things, and it'll pretty much be able to calculate exactly where to shoot. Could even develop prediction algorithms for moving targets. Oh technology, how I love thee. EDIT: Well, fuck me. They actually have put most of those things into this. That's pretty damn awesome.
I think you have to think less warfare, more tactical/SWAT type things. Like in the video, with hostage situations.
