In my mind this study really drove home the point that lots of open roads and unlimited bull tags usually means bulls don't live long.
Prettty much what I have always found. In Colorado,before the 4 pt restriction was put in place, probaly 80% of bulls killed were spikes, maybe even more. They did not live long enough to get wised up.For a few years it was slim pickings,but then killing a branched antlered bull was not all that hard, but still that 1-2 years that the spikes matured into 3-4 pointers,gave them enough time runnning with a herd,they figured out enough to stay alive that some matured into 5-6 x's.
