It was a fluke. Headshot ona squirrel (he was cutting up in a tree) from 100 yards w/ a4x scope. I couldn't range it, but after the shot I paced it off (I was taking big paces as well) and it came to right at 100.

I had a good rest in the fork of downed tree, so I just slid in underneath it and was popping squirrels. I saw that one that far off and thought, "well let's see", so I aimed high, had time to look over the scope, and saw him fall.It was pretty neat!
