Those are the dates I normally hunt MT due to work. They are usually herded up pretty good by that point as mentioned. I notice they go to their beds really early with the full moon, but come out in the evening earlier, and probably stay out all evening. Depending on where you are going, decoys can be helpful. Especially trying to peel something away from a herd. I have glassed from afar lots of small bulls running ridges looking for herds during the day during this time as well. Depending on where you are going in MT, wolves can make them quiet. It varies by drainage where I hunt. I've seen them screaming, crossed a ridge and spotted elk, and watched a herd rut completely silent. Enjoy it! I leave tonight for a week and can't wait!
