Using real bone antlers, I have rattled in several bucks and killed four as a result of coming in to a rattle.

I once had a large buck come down on the other side of a river and was headed away from me. I hit the bones and he turned and cleared the river so fast and was in my zone so quickly, I was not able to get into the shooting position I needed to before he was upon me. As I tried turn in my stand, a loop on my rubber boots twanged a stand cable. I witnessed why he was a big and mature buck. He left in the blink of an eye.

I only use the antlers in the post-rut and rut period.

Of course, my experience with rattling has been mostly in Illinois.
