QDM is the big antler hunters dream. That's all it is. Designed to grow big antlers for those that that's their thing. It really has nothing to do in most cases with the "Health of the herd". If that was the concern of QDM they would and should be pushing for "Does Only" in a lot of places. QDM was started by the big Texas ranches that wanted to beable to charge people $10,000 for shooting a deer. Now they're getting it. Without QDM there have and will always be the big guys who survive and become the boss of the local herd. The QDM craze was fostered for one purpose only.... BIG HEADGEAR. You want to practice it that's fine. If they legislate it that's fine. If all our herds were 1 to 1 ratios and BIG BUCKs we all will end up with Texas sized pricetags. QDM in all these high priced... big money markets puts the herd size way above the natural carrying capacity of the land with feeding and food plots. Which also seem to grow the towers overlooking them. They get these outrageous prices because of the unnaturally large numbers and ease of taking. They're close as you can get to cattle herds. You want it fine, but don't tell me it's for the health of the herd. The herd could care less if it's bred by a 2 year old or a 5 year old. AND, I never saw a 5 year old buck that tasted better than a 2 year old. Besides that... my old heart can't drag 250 pounds.
