we hunted out near the KS border a couple of years every buck we saw early and late had broken points, after talking to several longtime hunters they said that was the norm as the ground was missing some minerals, although they grew huge antlers they were weak, those deer were also very aggresive the buck I shot left a hot doe when I rattled the horns, never had that happen.
I passed a nice buck that was broken up this year, he was only a 3 year old, if he would have been old I wouldnt have hestitated.
