Coyotes are pretty smart.  They learn real quick what a rifle is.  The slow ones don't get the chance! 
They are not hunted in the parks and forest preserves around here so they get pretty brazen. The park superintendent at a local state park referred to them as "pretty friendly" in an email to me one time. I don't think they are friendly at all.
