Guys, there was a lot of luck and some specialized equipment to make this happen. Most scopes and mounts would have run out of adjustment for such a shot. Maybe he used a prism of sorts to beef up his scope magnification and get more elevation, but even then this shot was a lot of luck. Lots can happen to a bullet traveling that far. Not saying these guys aren't skilled by any means, but from my experience a shot like this requires as much luck as skill. I suppose if the person stood still or stayed at the same range the whole time then it's possible it could have been walked in with spotted misses from a forward observer. Either way, not an easy shot.
