I don't know everything there is to know about QDM and i will be the first to admit it. But i really don't see the reason to shoot a 1.5 - 2.5 year old bucks. If i am going out to fill the freezer i am going after the first mature doe i see. I agree with TLBS and will not shoot a yearling. I know the whole key to bigger deer and a healthier herd isn't letting the little deer go but i think it is a good start. The only time i try for one of those little guys is when i have the camera in my hand, I get more satisfaction just watching one of those immature bucks go buy then i would shooting at it, just knowing i probably could have shot that deer but instead just watched him go buy and gave him a chance to get another year on him is good enough for me. Good huntn'.
