Have no doubt a wrist rocket or equivalent of an old Wham-O and a ball bearing could kill a rabbit.

Problem is, hitting the damn things, especially if moving. I spent many hours with one as a kid, and best I could do was maybe within 6". Would not want to count on one to stay fed.

Fishing, trapping, and spearing are definitely better more reliable ways of staying fed.
