This kind of goes against what i think, but I guess anything is possible. I recently watched the new Drury Outdoors videos, and I think it was Dream Season 11. Jared Lurk killed an 8.5 year old buck called Corkscrew. They saw this deer at 3.5 and Jared passed on him at 4.5, and for the next 3 years they saw no sign of him at all ( no pics, no sheds, no video, nothing...) And you know if a deer goes unnoticed on the Drury's land it is a miracle. He must have had a home range of about 100 yards. Older bucks are some amazing animals, they devote their lives to survival and become some real experts at it.
