It looks like a short stumpy pointed no powder 458 Socom. Just get a Beowulf and be done with it. They make Hornady aerodynamic ammo that works great around 1900fps. And lots of powder to expand.

I also wonder if you could cut a Beowulf case down and use a Barnes Triple Shock BMG 647gr and go sub sonic...

My first thought was a sawed off .458. .458 SOCOM does a pretty good job loaded subsonic. I have some factory loaded 500 grain soft nose pills that will hurt something big if they're close enough.
