Here's a quick story about how grunting can work. I had a stand that I like to hunt opening day, I shot a buck there 4 opening days in a row. Well one of those was in a bachelor group. They came in but were just inside some really thick, nasty stuff and I could see them pretty good but it was too thick for a shot. So I gave a couple of toots on the Rod Benson and the biggest one about ran up my gun barrel. He can on a string at a very fast trot. Shot him almost straight down, he fell about 6 feet from the tree I was in. I think he was the dominate buck of the bunch and wanted to show his buddies and the new guy he was boss.
