It says it took them 69 attempts to hit the target. I wonder if that is repeatable, or did they just get lucky? The video gives the impression that the rifle was handheld, so they couldn't have dialed in shot like artillery. But if they had, what would the spread be like at that range? Would it even be possible to reliably hit the target? If not, is it literally just dumb luck?
