I hope not. There are what, maybe 9 pellets of 000 in a round?
Unless you're really up close and personal, he can slip right through your pattern.
For hawks, you want to use #6 shot. That's all I ever use for turkeys.
And with a full-choke barrel, at 40 yards a robin won't get through the pattern.
Animals that are cared for are considered Property in most states. You get a hawk catching your free rage chickens that you feed and depend on for food and eggs, no question asked the Hawk has to GO.
Cats are also property if fed and given Vet care, so are small 6 pound dogs, they depend on you to keep them as safe as you can.
In some States it is illegal to shoot a Bear, catch one of them going after a calf or Foll and they be gone also.
Darn, were this Hawk to get a shining to your brand new car and decide to eat the paint or peck holes in it, perhaps get aggressive with the kids playing out side----Hawk be gone.
This is so stupid, Humans rights come before the rights of aggressive animals, and when a wild bird or animal acts out they may be sick with any number of diseases that can effect your family. One has the right to protect their Property, from all threats.
