We recommend making an imaginary "X" between the eyes and ears and placing the bullet in the middle of the "X." The “X” should be just above the plane of the eyes.
A .22 Long Rifle works well if you are comfortable with your proficiency and accuracy. It is low-energy, so it is less forgiving. A .22 Magnum Rifle gives you more energy, and less precise shots will be lethal to the animal. You can also use .22 Stingers or Velocitors (higher-powered .22 Long Rifle rounds). Please check your state regulations.
