Well, I hate to see your question languishing for days so I'll take a crack at it. Late October would be a good time to rattle, call, and use scents. Assuming the pre rut isn't really going yet, i.e. they haven't begun to chase and harass the does, bucks still are very interested in each other and light rattling and/or calling can definutely bring them in. When you're setting up, put out some buck urine in a couple spots 20 yards or so upwind of you. That will help convince the bucks that circle downwind that they are hearing the real thing. Just don't go at the horns too hard as it's probably too early for two bucks to be fighting over a hot doe. Good luck.
