Very seldom have had deer even react to a grunt call. The few times I have had bucks come in, at least they have all been decent ones. I have 2-3 differentcommercial brands and one "custom made" ... I cannot tellif one is better at attracting bucks than any of the others.I have had zero luck with a bleat can. In fact I ran off a monster buck last year trying to get it to turn reather than contiunue walking away from me. He came out on a woods road and was working scrapes as he walked away. All I had was a rear end view. I rolled the can one time thinking he might at least turn a tad, buthe buste out of there like he was shot out of a cannon !!!
