I will contend that these clubs have good bucks despite killing so many does not because of it. You said they did not shoot small bucks. That is your answer for having bigger bucks. Killing does does not make more or bigger bucks. Never has never will.
So called not enough does is going from seeing 15-20 deer every weekend. Killing good bucks every year. To seeing 5 deer a year and not a single decent buck. That is so-called not enough does. Thankfully that club next to us that fucked everything up saw the error in there ways and changed.. thi gs are better now. Just took it 20 years to recover.
