I just answered a thread over the weekend on another board , that asked what was the first friearm I ever shot.
I answered .22 bolt action a broad creek scout camp.
I hope the kid is ok, .22 he should be. When i was in the 6th grade some farmer kid at my school shot another farmer kid in the leg with a .22, "just to see what would happen", and the "victim" turned out ok. We were all in 4H together , and by the time they were teens they both laughed about it.
Almost 20 years ago when i was at camp, the range seemed really safe. Almost everyone at the camp got one range session, even if they weren't taking the class for the merit badge. You got a rifle, a lane, safety glasses , earplugs, and a block of wood with holes drilled in it w/six .22 bullets. I remember it being very strict and procedural. Something really strange would have had to been going on for someone to have gotten shot at their range.
