Big 8, I don't think the late shedding is anything to be concerned with. It is an individual thing among the bucks as to when they lose their racks, and you will find those that lose them early will continue to lose them early, same to be said for those losing them late. A variable that will affect a certain individual's timing is his health and nutrition level. You will find that your buck will lose his antlers the same time every year, sometimes within days of the year before, unless like I said his health or nutrition is down.
