RE: 28 gauge shotguns
Like frizzellr said, a .410 has harvested many a squirrel for me and my grandfather. He started me out with that gun. I was also 13 at the time thought, and like frizz said again you have to aim it. A smaller kid needs to be able to point. I don' t know anything about 18 guages except that I never see any 28 ga. ammo in the stores.
