Lazi. I used an RWS Diana .177 to kill a dozen Skunks. Only one needed 2 shots and it was about 20 yards away. I took all head shots from the side or where the skull meets the spine (base of the skull). And my rifle is almost 30 years old, but even today it still puts out about 950 FPS. If you want a “Survival or Hunting” rifle, don’t cheap out.
