Did anyone else cringe when he was shooting off the rock with the forearm resting on the rock? Or, when he leaned the shotgun down with a clunk onto another rock? Maybe it is me, but I wouldn't do that on any of my guns. My hand would be between it and the rock.
His door shots I think were right at the side collision bars. Slightly down would make quite a difference. I liked the video, and he displayed good trigger finger discipline.
Exactly why he should have tested some birdshot from Valuepack to high brass!
Birdshot will definitely ruin your day, but it might not take the fight out of a motivated attacker immediately. I'd leave birdshot for the birds.
