Inlaws family shot a 4pt during gun here in MI the 3rd week of Nov. When the deer hit the ground, the right antler came off. When he was dragging it out of the woods, the other side came off. In that neck of the woods, they found several sheds late Nov/early Dec. Kind of strange for MI I thought, but you never know what was going on in that area. I see deer through late April with horns on their heads.
