That is not a question that can be definitively answered. It depends on the deer, its breeding and food. Some deer will develope earlier than others. Some deer will never be an 8 pointer. Where I hunt there is a tremendous body size deer with an amazing and heavy spread. It has been a 4 pointer, two on each side for at least 5 years and I suspect will be a 4 point until it dies. In PA it need 6 points to take it in the zone I hunt, except for Jr hunters, active military on leave and disabled hunters with a permit to hunt from a vehicle. I keep hoping my grandson gets a crack at him. I could have killed him a bunch of times.
