I fully understand all this.
But imagine, if one of your hunters was by himself consistently killing 3 of those bucks annually, while most the others weren't getting one (and there were only 6 total available for harvest).
Such can create conflict among the group.
In my area, long-term, a sustainable harvest of 3 1/2 or older bucks has only been about 2 annually per 500 acres. In most cases, or most family farms, most clubs, etc., there really aren't enough 3 1/2 & older bucks available for every hunter to even kill one (and have ongoing sustainability).
In my situation, we were not producing enough older bucks (3 1/2 or older) for every hunter to have a reasonable opportunity at even one, if a minority of accomplished bowhunters (and muzzleloader hunters) were taking most of those bucks before most the others even went hunting.
We came up with something on buck limits that is working for us.
We have a 3-buck limit spread over 2 years.
This is more or less a 1.5-buck limit annually.
With this, any hunter can take 2 bucks,
but if he does, his limit is 1 buck the next year.
So long as a hunter only takes 1 buck annually,
he always has a 2-buck limit.
