Wabbits are easy to kill. Had an old BB rifle that was so wore out that you could see the BB leave the muzzle & follow it all the way to the ground! If holding the rifle at the shoulder, from our patio, the BB would hit the ground about the time it got to our backyard fence, about 60 ft! My wife caught them (cotton tails) in our garden just outside that fence. Intending just to run them off, she shot up into the air. One of them was hit & died on the spot!! She really grieved about that & had me bury it when I got home. There was just a barely discernible mark on the back of it's head!
