I'am a conficted felon and I love to hunt... will I be able to get a gun or bow for hunting

You are not going to get a gun. Check the following guide and see:
Gun Control laws - Information on the law about Gun Control (http://law.jrank.org/pages/11807/Gun-Control.html)
You may get a archery license - check your laws in Il, but bowhunting should be legal for you.

Also see this post: J_9, one of our moderators, has some excellent information posted there:

My husband owns a sporting goods store, so I can tell you no, you won't get a gun for hunting. Impossible, no way.

Now, you can get a bow and hunt during bow season.
