Ok guys hate to burst your bubbles but there are a number of guys here in PA that do this every year for deer. They set up on logging and forestry roads glass the mtn across from them and then decide wether to shoot or not. They take shots from 500 yds. to over 1200yds. I have done it myself took a doe at a little over 700yds. first shot hit just to the right of her second in the neck she dropped in her tracks. So yes it can be done and is every year here.
