FWIW I tried some 3" turkey loads in my O/U and HOLY BAJESUS I wouldn't wish those things on ANY kid. Not unless they are shooting a semi auto to absorb some of the recoil. I've shot 2 turkeys with the 20 ga using 1 oz, heavy field loads, In #4s, X full choke and they died just fine. Of course both were spitting distance. Patterning the load is the key.
