If they are truly a nuisance, people would be glad for you to hunt them. It would be worth making a few phone calls. A call to the game warden may get you setup with a place to hunt, they will be the first to be notified of nuisance deer. Also, a good idea is to earn your way to hunt their property. Trade work for hunting rights. Then if you prove you are an effective shot, you will probably get calls from other landowners that feel deer are becoming a nuisance.
