"No one shoots deer with a shotgun, silly. You'd never get a clean kill.
So you can't say no one ever told you: Shotguns are for birds, such as quail, partridge, pheasant, and turkey.
Small caliber rifles are for varmints, such as squirrel, gophers, and foxes.
Game rifles are for your big quadrupeds: deer, elk, and feral pig."
