Like Daver said... way too many variables.. Your best bet would be probably the last week of October and first week of November will give you your best results. The bucks are looking for that first doe and fighting or tending grunts are something they will likely check out, thinking that maybe another buck in the area is tending a doe or a couple different bucks are fighting over one. You can start tickling the antlers from Oct. 1st on. Once hard horn hits, they are constantly sparring/fighting all the way until they shed. Me personally, I don't like to blind call a whole lot, especially early. I'll maybe do a rattling sequence twice a sit when things really heat up. I have one deer I was hunting last year that was very call shy. So, if I can find him again this year, I probably wont call at all. I have also grunted in a buck a couple hundred yards across a bean field on Oct. 1. Also, results will depend on your buck to doe ratio. If there are few does and a bunch of bucks in the area, they will be competing a lot with one another. If it's the other way around, they don't have to fight much at all to get a doe.
