Get you a .17 HMR with a really good scope on it and you can pick them off at 100 yards. Academy has them for around $300 These are really straight shooting guns, use cheap rounds, and my DH can shoot dime size groupings at 100 yards. I even impressed myself when I shot it (the first rifle -- or any gun--I had shot in 25 years) and shot nickel sized groups at 50 yards. You could pick them off from a distance and they would never know what hit them.
