Me and my friend were out shooting armadillos; he had his savage .17 and I had my marlin 795 22lr! He shot one that, no lie, blew the shell and most of his back muscle close to his neck! The dang thing preceeded to hop around and try to find his hole -the best he could- for about 2 minutes! I've personally shot them in the midsection, guts hanging out, and still run off!! Tough little dudes. Are count right now is at about 32.. in 3 or 4 trips out
