I'm pretty impressed with mine-it will shoot 1/2" at 50 yards and the ..25 pellets really make a pop when they hit! A couple added bonuses are the safety factor-like a wiffel ball,the pellets lose energy much faster than a .22 40 grain bullet and don't destroy as much meat if you don't make a perfect head shot.I think the PCP air rifle may well be THE best squirrel tree hunting gun?
