When I wasa kid we (my brothers and I) used to shoot long and recurve bows at 75 yard targets, you know the big round straw ones with the cloth bullseye target that tied around it. They were big targets and we would be happy just to land one on it anywhere, but for the most part we could hit the target 6 out of 10 arrows. Sometimes more, most of the time less.Man them old arrows would have such an arc! Talk about instinctive shooting, we'd be aiminglike 8ft over the target just to get them suckers to land.

Three inch groups is about the size of a baseball. Man it would be hard to see that, much less put your arrows into it at that distance. It can be done and like someone mentioned the Olympicshas an80 meter range (I think) Even they don't put arrows in three in groups consistantly at that distance.So while it CAN be done and maybe even the kid got lucky (possible) and shot one three inch group at that distance, I highly doubt he can do it on demand.

I highly doubt he did it at all.
