Whats the biggest aniamal youve killed with an airgun?

[Ridge Runner]

useta shoot squirrels and rabbits with my bb gun, never owned a pellet rifle, I do know that they are making elk capable air rifles now (.50 cal) and also doves and canada geese are federaly regulated migratory birds, it is a federal offense to shoot either with a rifle no matter how big of nuisance they are.
