RE: "Success rate" on "mature" bucks
For the sake of the thread.....size of rack is unimportant. A 3.5/4.5 yr old buck is that age, period.
I don't think they store memory; woods savvy or increased intelligence in their antlers!
So DC....if my math's correct.....you're thinking a success rate of about .266 is "good"? (every 3 years is .333 and every 5 yrs is .200)
