If the young lad has been brought up on firearm responsibility and safety. then I certainly don't think 6 is too young. My 3 boys have all shot deer, ducks and doves before any of them had started school. Old Pop's didn't even have to shoot a deer last season (doe, button buck and 8 pointer) were shot by my 3 boys in early season with a crossbow. Twins are 5 and oldest boy is 8. Freezer was full so it allowed me to concentrate on pheasents and grouse the rest of the season. Still got a deer and a half in the freezer.
Definetly open the choke up on that .410. Reduced felt recoil and better pattern with steel at the very least.
