It's all about location/hunting pressure.You can't kill a mature buck consistantly if thereisn't many to kill. I use to have a great bow hunting spot, for two years my brother and myself took two 3 1/2's and one 5 1/2. Then the CWD craze kicked in, the Wis. DNR gave eveybody in the area the right to kill as many bucks as they wanted. The adjoining landowners do not practice QDM anda public hunting area is across the road. Many immaturebucks were shot. The last two years I have only seen two bucks on that property that I would call mature, they were both on my trail cam. Luckily I have other places to hunt.
So, to answer the question, unless you can control alot of area, including harvest numbers. IT'S NOT EASY!
