Never heard of a 13 pointer being a non typical. Non Typical usually means that the buck has unusuall antler growth. Such as drop tines, split brow tines, 3 racks, stickers going in every direction. But even if the buck has a drop tine or a split tine, doesnt necessarilly mean he is non typical. You can shoot a 19 point buck and it could have a perfect symetrical rack, this is not concidered to be a non typical buck.
