My Nephew ranged a pair of Blue Grouse @ about 55 yard --- said if I could hit one in the head; he would clean it. One shot from my S&W 34 revolver -- right thru the eye. I acted like I did it all the time.

That was a while back, but last Summer I was shooting Richardson's Ground Squirrels with a very accurate 10-22 and one popped its head out of a burrow @ 214 yards. There was a full value 10-12 MPH breeze. Only his head was showing. Got it first shot. The headshot caused him to do the jumping jack routine or I would have never known that I hit it.
