Lung shot, every time. About 80% of them fall in their tracks, the rest don't get far.
Can't say how far OPPOSITE my experiences are with N. MN whitetail deer!
I've shot many deer in the lungs, broadside and NEVER dropped a deer in it's tracks. That's a fact.
Broad general statements like that confuse people. The reply should have been backed with data to reveal "why" those 80% of deer dropped in their tracks.... and 0% of mine did NOT. LOL!
I bet it has to do with 3 things:
1.) Just how high in the lungs. (I'm thinking higher to shock the spine)
2.) Faster ammo has more energy to transfer once the bullet hits.
3.) Type of bullet. Bullets that expand better will transfer more shock energy.
The deer I shot in the lungs were mostly shot with 30-30 and .243. Fact is, 100% of them did die after a brief run, but 0% of them dropped in their tracks. Most all of them shot in the middle behind the shoulder or just slightly lower. Nothing high near the back/spine area.
When giving statistics, it helps to offer up some detail to explain the situation, which helps the reader determine the "why" of something.
Personally I do take other shots besides just double lung that are effective, but are deemed by some to be an unethical shot. That really should be determined by the shooter. Especially if that shooter knows their ability and stays within those parameters.

I was simply relaying my experiences. No need to jump down my throat like a drill instructor during hell-week.
In the past few years, I've shot deer with a 30-06, a .35 Rem, and a .50 caliber muzzleloader.
The '06 hits them like Thor's Hammer. Shots through the center of the lungs make deer dead before they hit the ground. This is shooting Federal ammunition loaded with Nosler ballistic tips. All shots have been inside of 50 yards, so the Nosler is no doubt going along at a rapid clip. Damage to the vitals is impressive, and exit wounds are usually quite small considering the mayhem that the bullet does inside the deer.
The .35 Rem claimed it's first deer back in October, a big fat doe who had her lungs utterly pulverized from 100 yards away and ran 30 yards before hitting the dirt.
The .50 cal muzzleloader was shot with 370 grain maxiballs, and the maxi's are the ones that caused spinal trauma. I don't use them anymore because I noticed that they do screwy things inside deer. The shot that comes to mind was angled slightly down and centered on the body just behind the leg, but the big conical somehow managed to arc up through the body cavity and come close to the spine, while still managing to take out the lungs. I can't figure that one out.
One thing that I think has a lot to do with the fact that I drop quite a few deer is that I shoot deer that are completely relaxed and at ease. I've never taken a shot on a spooked or running deer. I think that their mindset at the time of the shot can mean the difference between expiring instantly because of shock or loss of blood pressure, or running 150 yards on adrenalin with the top of their heart blown off and their lungs splattered in the grass behind them.
