I just watched this video. The problem I have with it is the poor video of the target. They don't really show it. Also the time of flight is way off. In the video from when he fired til the time the spotter started calling the Impact it was about 4 seconds. I put in the numbers into AB and at 2000 yards the time of flight is just over 10 seconds. Big difference. Now it could be because of the video but if you were going to attempt a shot like that wouldn't you make sure you have good video of it?
