The link did not work for me so I could not see the gun. Any air rifle with a listed velocity of 1000 fps or better is what you should be looking for. Gamo makes PBA Raptor ammo that is fantastic. It is a ballistic alloy that increases the velocity of any gun as it is lighter than lead. I have shot things that have died faster with that ammo and at greater distancesthan with any other. What ever gun you do get, look into getting that ammo for hunting.
