I don't think there is anything wrong with this way of hunting, although I think according to your description of the way you hunt, you are fairly new at hunting deer. Is this correct? If so, then IMO, as you mature as a deer hunter, after you have several deer under your belt, you may decide to only hunt a mature buck for instance which would make you try to understand more of the habits of a mature buck and concentrate on more of the lifestyle of a mature buck instead of just a food source.
