I was thinking the same thing that Drew said. You might want to get an eye exam. You only said that you were shooting "clays"- were you shooting trap or skeet? Sometimes people have a tendency to start out with a 20 gauge, but sometimes they have a severe recoil also. He might be pulling his head off of the gun because it could be hurting him when he shoots. I always thought that 9 years old would be kind of small/young to be shooting trap and/or skeet. I know. I know. "My grandson, etc. etc. etc...!" But I would watch him closely the next time he shoots and see if you can figure out what is happening. And did you ever think, maybe his shooting clays might be messing up his shooting at video games. Just a thought. But, good luck.
