I like AR's, but the issue will always arise in pockets within counties where over-population is an issue. My county addresses does with MLD permits for the county WMA members. I am in an area where I can only kill does in archery season. But with the MLD permits it allows me more time and more tags to control numbers.
Some questions for you- What is your buck to doe ratio? What is your CC? What is your fawn survival like over the past 3-4 seasons? Do you do surveys every year? Do you kill all the does need to be killed as per survey? Do you have good records of harvest deer and an annual survey for the past 5 yrs? How many hunters on that total acreage around your and on your lease? As and example, will you be okay with MLD when they limit your buck harvest to 10 bucks total on the 4500 acres and you have 20 hunters due to buck to doe ratio?
For me, I would concentrate on what I have to work with now. If I needed to shoot bucks off due to a good buck to doe ratio, then I would shoot spikes and a trophy. I would shoot all the does needed to get the ration in line if needed. You can do more on a ranch shooting does at first than culling bucks. Letting the better bucks live to mature ages increase the amount of desirable bucks breeding.
