I don't care for the term. Here in Tx on some highly managed ranches a buck could be considered a "cull buck" because its "only" an 8 point at 3.5yo. It may be 140 inches but because its "only" an 8 and may never be a 10 or 12 its considered a cull. I think that sucks. Oh and you can bet your butt they charge a nice fee to shoot that "cull"!
