The term "cull buck" is the lamest term and idea I have ever heard of in the whitetail world. Does anyone actually think they'll get the genetics out of the herd by killing one buck? You better start finding his sisters too and get rid of them.
IMHO Texas ranches came up the the term "cull" and "management" bucks to find a way to make some money on the less desireable bucks. Most everybody wants a "trophy" buck, but won't pay for it. So they came up with "management" buck, dropped the price and now people will pay to shoot them.
Want to determine a true trophy? Let's look at their teeth.
Dan.. you and I are like peas in a pod.
