I personally have a VERY hard time believing this claim. There are so many variables in a shot at that distance, wind speed and direction, what point on the horizon to you pic to aim at, and could you even see anything that far due to your iron sights being gigantic in comparison, short sight radius, natural wobble, etc. etc. Not to mention he used bulk ammo, no fancy target ammo. In my experience, there is a considerable difference in consistency in cheap bulk ammo. I have shot with some very good bullseye shooters, who use very high quality guns, and ammo, and are excellent shots. If I were to look at one of their 50 yrd targets, and multiply by ten, they would be lucky to hit anything at that distance. I'd be lucky to hit a barn.
