My favorite way to do it was buy a rabbit from tractor supply, break it's back legs and tie it to a stake in the middle of a field so it screams. Set up 75-100 yards out with a 22 magnum with a red light spotlighting the area so their eyes reflect. Then aim for the gleam.

In the back yard, even a medium power pellet gun will kill them with a well placed shot, eyes, spine, brain.
