Hey Scotty, As you know feeding (baiting) wont hardly work on a mature buck and your chances of catching him during daylight are slim and none. Your best chance is during the rut, or pre-rut. Find where he is scraping and get up high and wait.......if the does are there, he'll show eventually.
I hunted in the national forest near huntsville, tx for 5 years before I took that big 8. I took some spikes and 4's during that time, but it took me 5 years to get that 8. I've killed many deer, bigger deer since but thats the one im most proud of. good luck

If he is coming in consistently at night then he is probably on to you and your patterns. I would try to figure out which way the deer is travelling and set up a new ambush spot in a diiferent location. These creatures learn quick or die.

Chesters right move up his path and ambush him coming in from feeding or headed out to feed.

Try baiting every other day at first light. Then hunt it right after you bait it. I still would not hunt that spot more than once or twice a week. Some of the deer will want to get to the feed before the others eat it all. You will most likely get a chance at a doe or young buck. I have never seen ANY large bucks on the feed during hunting hours.

They usually hangup out in the transition area under cover till nite time.You will have a better chance to ambush him in this cover by setting up 100 yards or so back . This way you may get shot at or around twilight time.
