when I was 13, my bro in law and I went to see a guy about baling some hay for us. He was laying on the roof of an old shed, shooting a Remington Nylon 66 at the heads of turtles in his pond, 50m or so distant. He was having no success, due to the fact that he didn't know how LONG their neck is. The turtles were slaughering his ducklings and he got po'd. All you have for a target with the 22 is his head and it's a very small mark, drifting a bit, too. He missed a dozen times , went and got his 3006 bolt action and started aiming low and well back from their heads. Then he killed a few of them. At a low angle like that, the 22's pierce almost no water at all before being deflected.
