I never have been much of a predator hunter but had a friend in Montana I used to go out with now and then. He called at night but never saw him call one in. The coyote's I've killed, I bumbed into hunting something else, just been a few. Shoot For some reason I even bought a call. Know what I found out? Use the fawn in distress call and every doe in the country come's in! There was one predator I did hunt quite a bit. Talked to a guy from Kansas that did varmints for the hides and he called them Prairie Sable, house cats!
