For a hunting rifle, I would strongly recommend against the JP Bennie Cooley brake. Permanent hearing loss will happen, sometimes even for bystanders who are wearing ear pro. A simple flash hider is fine on a 20" barrel. The guns don't move much at all, and your son will be able to spot his own hits with practice.
