That weapon appears to be too high on his shoulder.
His aim for skeet is far too low.
What exactly is the “smoke” coming out of the top of the barrel? It’s too far back to be of consequence for stopping barrel jump.
What’s with all the smoke. He would have had to fire a lot of rounds to produce that much.
That was going to be my second question. I think they don't want people Photoshopping this because it already has been Photoshopped. I also agree with you on the butt against his shoulder. That isn't the way someone who "shoots all the time" would hold that shotgun. IMHO.
See #42, the smoke does seem to fit where the port holes are on that.
