This might be a very stupid question and one with no real answer at all. Last spring I got my first buck that was a yearling. I have no idea with being so new to raising deer weather he grew a good first rack or not but by looking at many pics on here he was very much on the small side in comparison. My questions is when does a buck make his biggest jump and is it realistic for a buck to put on 40-50in of antler from yearling rack to 2yr old rack?
