You could hit it with a .22 at 2000m but damage would be minimal to nothing. The larger calibre anti materiel arms would be the choice if ya had bad intentions. Gruesome thought. Desert Eagle more of a movie weapon than anything serious. How do ya like these petite little actresses/actors waving large calibre firearms around in movies and spraying ammo around the landscape. I reckon the actual recoil from live ammo would instill a little more respect as blanks are all very well but the noise, flash and kick from live rounds is as rump steak is to soya mince.
