Many Americans like "crowbar" game guns and light as a "feather" rifles. While typical laddie would be best served with .30-06 occasional round of skeet or trap with Mossberg Ultimag and bunch of 3.5" shells would be good practice to get used to heavy gun recoil. The only downside is pump action of said shotgun so perhaps smoothbore 3" Marlin bolt shotgun would be a better choice.
