Use the blunt points and aim for the head. Otherwise use a good 3 or 4 blade muzzy around 125 grain and aim where the neck meets the body. Stay away from the wing area. That area is like body armor and I have seen it stop #6 shot from a shotgun before.
Also be prepared for a quick follow up shot or to run over and wring the suckers neck while it is flopping around after being hit.
