I'm with Old Buck. I would say to have a mature buck, you have to be in the 4 1\2--6 1\2, neighborhood. Not saying that you can't see a big rack earlier than that, because you can. As far as genetics, you do see some pretty sorry basket racks, year after year. On my property I see baskets often, but anywhere close to the river it's been my experience to see a lot of them due to travel. If you are trying to get bigger bucks on your land, I would harvest a lot of does, and thin out the old basket bucks. If there real gray in the face, or have a big body, those are the guys to go after. Never take a button, or a spike. And let the bigger young bucks go, and you'll get your maturity level up.....
