Way-over-yonder deer? Well, when you're in rugged desert mountain country that has a sparse deer population and a sixteen-day one-buck-only season, and your odds are such that a 400- or 500- yard shot is not at all improbable, developing gear and skill becomes somewhat important.
If you want to eat deer meat, anyhow.
