Finally on the board. Had 2 out behind the barn but by the time I got the rifle they were 600 yards away behind my neighbors barn. Called her up to ask for the all clear. Try to get them closer but they stopped at 540. While on the phone with the neighbor I asked to to whistle when I was ready. Worked like a charm. They looked back at her giving me a shot. Hit the first one a little back and while it was flailing the other stood for a shot at him. Dropped it in it’s tracks. The neighbor was excited and added them to her pit. 🤣
