Thanks for the suggestions it’s still a little bit early to get him started but I’m trying to get ready for it. I had my nephew out there shooting deer when he was 5 and my son is bigger than he was. He had a 243 and still has it so I guess I’ll just go with what I know. Just didn’t know anything about the 6mm creedmoor. We never really had any trouble out of the 243 with recovering deer. Only one time that he double lunged a doe and we didn’t have any blood trail in some super thick overgrown clear cut. Never found that one and I had the hit on video.
