I was trying out my 22 CHeetah several years ago with 60 gr Sierra Hp loaded down to 4060fps .A full grown Texas whitetail doe stood facing me at 127 yards (measured after the shot), the cross hairs were placed on the neck where it meets the body,trigger was squeezed, doe dropped it its tracks....literally! The bullet traveled 16 inches down the spine ,blood shot the front shoulders,ruined both back straps and tenderloins with bone splinters,as well as the tops of the rear hindquarters. I have never before or since seen as much destruction of tissue from a shoulder fired firearm.Since then I use head shots only with the Cheetah,with the same destructive results but limiter to the head, usually removes the brain completely regardless of the angle of entrance.Needless to say Jack Rabbits and Armadillos are very dramatic and not for the squeamish!
