I was at my friends property zeroing the scope on my new FX Wildcat with the JSB 18.1 domes (890 fps). He has a ground squirrel problem and I was hoping to line one up in my crosshairs but no luck. Along came this tree squirrel around 15 meters on the fence. I did not have time to adjust my focus, but I held under and pulled the trigger. The squirrel did a crazy back-flip and lost it in the bushes, thought I may have missed. After recovering it, this was the carnage. Boy does this gun hit hard!
