Nice buck!
I lease some ground in Southern IL with a few guys. One guy has killed two bucks that look exactly like that one; wide, good mass, very similar tines.
You don't hunt near Mounds, IL do you?
Probably just coincidence, but I do notice that a lot of the mature deer seen/killed on our farm in MO seem to have similar antler characteristics. The two bucks my buddy has killed in IL are definitely similar.
