Hey Ken, My answer to your question would be to judge the deer to your past kills. If you have a buck come by that is bigger than your last I would take that buck. You really can't manage a plot of land well until you have at least 1500-2000 acres. I have never put restrictions on myself as far as how big a deer must be to shoot, however I try not to kill any smaller than what I have already killed. If a young deer has a cool rack (drop tines, odd shape, different characteristics than normal) I will take him so I can mount him and keep him that way. You never know if you will see a deer like that again.
