I thought fake when I first viewed. He did not flintch when it failed to fire and missing the target at that range. But when stopping at about the 24 - 26 second point you can plainly see the image of a shot colum and hat lifting. I now think a very good fake or a lottery win wasted for surely he can't have any luck left. I bet he did not shave or use after shave for several days.
There is a very good reason the NMLRA has a rule against blowing down barrels. A guy walks up to the line and has a cap go off but it does not discharge. He drops the rifle down and blows to check for a loaded gun.
