I agree with the posts that tell of bucks finding places to stay that are "out of the way". After a day or two of slugs flying, think like a pheasant hunter. How many stories have we all heard from pheasant hunters jumping the "biggest buck I've ever seen" from the middle of a draw that no self-respecting deer hunter would normally pay attention to.
If the big boys are in the timber they will sit tighter than bark on a tree. Several years ago I arrived at a farm to hunt pheasants during the second slug season. About 30 locals had just finished an ol' fashioned, "if it's brown, it's down" drive when we arrived. ( Never mind that they didn't have permission to be there. I did confront them regarding their trespassing and got the old, "we have hunted here for years" line. What to do, 2 against 30 didn't really seem like a good idea that day!) Long story, we went ahead and let the dog out and started hunting. Not long afterwards, my dog jumped a big buck out of an area these folks had just been through. I had already walked past this buck, no more than 8-10 yards away, when it jumped. I am certain that it would have stayed put had not my dog rousted it.
I could tell many similar tales, but the morale of the story is to think differently when hunting bucks that are pressured.
