I'd say that's a hunter safety video all by itself.  Can't disagree with a thing he said in it and testing actual firearms on camera with actual loads and barrel obstructions is very valuable to today's young video oriented hunters.  I've done some upland and marshland hunting where the chance of a barrel obstruction was definitely there.  I've never had one I didn't catch before firing a shell and none of mine were as bad as what he did in the video with the dirt obstructions but the point is you have to be vigilant about that kind of stuff.   Good video.  Thanks for posting it.
