From my experience with my son, I have limited him to 200 yards thus far. He is only 8. When he progresses at ethically taking game I will give him a longer leash on shots he can try. But a 350 yard shot for him right now is out of the question. And he has killed quite a few deer. But hey whatever the responsible adult with the kid thinks, then go for it. Each their own.
I'm with you there. It's important to recognize the limitations and stay within them.
