This is the point at which you must make your move. You can stop a broadside deer in its tracks with a quality bullet or slug by firing through the near-side shoulder and into (or through) the off-side shoulder. If you have the abilities, equipment, and time to be extremely accurate with your shot placement, hit a little high in the shoulder. This will bring down most any large game animal instantly. The best way to ensure a quick death is to shoot a deer between the eyes at close range. This will kill it instantly. Shooting a deer in the heart or in the chest will only cause it pain and sufferings that will last until it dies of its injuries. It's best not to aim for anything other than a perfect headshot! Of course, if you don't have access to these kinds of weapons or skills, then you'll need to find another way to kill your deer.
