Few elk hunters even know how deadly rattling can be for calling-in elk. Many hunters recommend that when usinga rattling bag, try to make the bag sound like two young bulls are sparring over a cow in estrus. When the big bull hears the sound, he thinks to himself, “Who in the world is that fighting? Is there a cow in heat down there? I better go check it out.” When you use a rattling bag, you’re simulating a fight in the schoolyard that everybody will come running to see. Using a rattling bag for elk hunting is much like using a bag for whitetail hunting. You can’t go out and expect a bull to come running to you as soon as you rattle the bag.
