Filming hunts is hard because the main star of the video is not privy to the script. So many shots do not get captured because you just never know when and where the deer are going to show up and give you a good shot.
Every now and then they do seem to follow the script and you get amazing footage like this one posted to Facebook by The Big Buck Registry. It appears to come from Cuz Stricklands Instagram account and it just shows that sometimes it pays to have a camera in the right spot.
Guaranteed that buck is not running far. Congratulations on whoever the hunter was that made the shot.
