The main rule is once you go into the three figure club on big game you should know something about shot placement. When you have dressed out 500 or so you will know something about bullet performance.
TV shot placement is for movie stars showing the generic way to shoot a deer for the beginner. Arrow shot placement is different from bullet placement with the ideal shot being in the lower quadrant behind the foreleg. Which looks to me like a heart shot.
The center lung shot which is tight behind the shoulder is both a good bow and rifle shot but for different reasons. First it is the easiest shot as the biggest target. For the bow hunter it gets both lungs and the deer should drop between 50 and 200 yards. For the rifle hunter (depending on the rifle) this is a fair shot or a good shot depending on the equipment.
Determining the deer's reaction: If you are hunting in an area where tracking is easy; snow, or park like forests you can afford to let a deer run a bit after the shot. Then you can lung shoot a deer and let it run. Unfortunately I don't have that luxury in my part of the country.
I have to be very selective in choosing a bow hunting spot and be very selective of the guns I use for deer hunting. If a deer runs more than 50 yards in a Louisiana briar patch you may not be able to get to it. So you have to use a DRT Weapon (Dead right there).
With the bow, just don't go there, and that goes for 223 and 243s too. In heavy triple canopy forest (jungle) you must think of both bullet and arrow deflection, learning to spot a clean path all the way to the deer and set up the shot. This is difficult with high trajectory weapons like vertical and horizontal bows. This is the worst case scenario so once you get this right, more open terrain wont be as difficult.
So how do you drop a deer "right there?" Well if you are a Texas market hunter with a 22 hornet, at about 40 yards or less you can shoot them at the base of the ear all day. Neck shots are very difficult with a rifle as they move too much, but a neck shot with buckshot is the same as a head shot on a turkey. I use this shot on Nannies when shooting for the freezer. Three buckshot hits inside 40 yards with 00 or 000 buckshot in the heart lung area is a DRT Shot.
With 308 and 30-06 class rifles, minus the 243, a center shoulder shot will an-core your deer right there. Just don't use a bullet designed for larger than deer as they may shoot through the deer and you have a bow and arrow situation. A 30 cal 165 grain soft point is about right.
How to mess up a deer..Magnums...You should avoid the 7 mm and 300 magnums with 140 and 150 grain bullets if you like venison. However the 325 WSM and 338 Win Mag are not that bad on deer with heavy weight , but light jacket bullets, and keep the speed below 3000 fps.
If you do use high speed calibers like the 25-06, 270, 257 WBY mag, 7mm and 300 mag go for a behind the shoulder shot if you can.
The high lung shot, is one to do if you know exactly what you are doing with a good rest. This is for the guy on the TV show that gets to shoot tame food plot deer with perfect broad side shots (I never get that lucky). Trouble is most of these guys cant shoot that good, but if you can....go in the upper quadrant, tight behind the shoulder. The idea is to put your bullet just underneath the spine but not touch the bone so not to ruin the back strap. The power of the bullet will shock the spine and deflate the lungs at the same time..DRT.
Now if you are a Big Bore Nut, like I am then you learn a new degree of death, known as "Elmer Keith Dead" Using 50 cal muzzle loaders and 150 grain powder charges,444, 45-70 with at least 240 grain bullets on up but with light jackets or pure lead like a Brenekke 12 ga slug and you get this effect inside one hundred yards. Shoot them right in the middle of the shoulder and watch the rear collapse, and then the front. Sometime they skid on the ground a little after they fall. Then you find out you can eat right up to the bullet hole. Pass it on...
