Don't try to joke with the boarder guards they have no sense of humor. Some years ago my buddy and I crossed over for a spring bear hunt. When they ask what was our reason to be in Canada my buddy blurted out, "We're here to kill some of your bears" next question, "Do you have any guns?" He say's, "no we don't need guns". Next statement from the boarder guard, "pull your vehicle over there".....they took EVERYTHING out of our truck and made us stand back and watch...… live and learn
So I watched the video. He is giving you a reference point starting center of center and moving 3”forward. That puts you 4-5” back from shoulder. He said a broadside shot to get two holes through them. All sound advice to me. I’ve killed 2 so far both were shot a hands width (4-5”) behind the shoulder and dead center of the chest. One fell within 25yds of my stand the other about 40yds. Listen to your outfitter he’ll not steer you wrong.
