I have to agree with Mr Pdevil. If I harvest a 6 point and he turns out to be a youngster, what would he have been next year. Probably a pretty nice deer. Thats the exact reason I feel antler restrictions won't work. You have to judge the whole deer, the body size(is he thick, or sway backed or is he still young and some shoulders to grow into) I saw a lot of 6's and 8's (Jackson county) that were young deer hanging on the buck pole. I'd rather shoot the spike and let youngster with the nice rack go if I were to harvest a young tender animal. On the other hand, if I wanted a doe. I would have to wait to shoot an older one, more mature bodied so not accidentally take out a button. What would taste better young spike, or older doe?
That said I don't have to worry...my luck prevents any thing shootable from coming into range. I did pass on two does, because they were marginal in size, one had a real pear shaped head, but I couldn't be sure by looking at her that she wasn't a button...I got one button 3 years ago and never want to again.
