2 inch at 25 wow I'm thinking thats off a bench....if its freehand he's all set he's got good eyes and hands if its not see how he does freehand.might want to keep him to 50 yards...my friend kids a good shot as good as most adults, sometimes we forget he's 11 ...75 yards can be alot of pressure...I passed a deer at 80 yards last year in the woods...I feel good to 50yds freehand after than i'd want to rest the gun unless there broadside wide open....
