I have never tried rattling or grunting on public land due to the safety aspect of other hunters. I have rattled on my property with somewhat success. I normally start rattling around the pre rut rut period when I'm seeing alot of bucks sparing on the property. I would typically rattle around a good staging area around a good scrape line. My techniques are just small clashes of the bag and a few grunts, the bucks typically dont all out fight on my property. I think the doe to buck ratio is pretty high.. Good luck this season and be safe on the public land..andrew
