If the breeding is still in the stage it is here in Iowa, hunt the food sources the does will visit in the evenings, and hunt the travel routes the does will take to their bedding areas in the morning and midday and you will find those bucks....or possibly some even bigger you've never seen before. While the pre-rut brings out the young bucks who are eager to get started, the older guys wait to show themselves until the does are actually in full-blown estrous. Then even the most wary bucks can't resist the urge to find some 'tang during daylight.
