FBI gel tests is sort of misplaced, You fellers think the "Gel test" are not a good comparison for real life ?

ya'll may be right as far as I know ?

The only comparison I have to people size targets is deer hunting. I've never been on scene when a people target has been hit.
Here are so observations I've made over the years from deer hunting.
1. I help track a deer that had been shot with an 30-06 180gr soft point factory load. The bullet went into the diagram on the lung side and exited in front of the hip. We tracked blood trail for at least 1/2 mile before we found the deer a half a day later.
2. I shot a deer with a 60gr. 22 cal Bator cast bullet from a lee mold (22Mag-velocity). The bullet went in high on the lung and exited strait out the other side (hunting from the ground) , just in one side and out the other - high in the back of the lungs. That deer went 30 yards and fell over.
3. Hunting from a tree with a 38 special 140grSWC/1000fps pistol 4"barrel. The shot went in high in the back of the lungs and exited front part of the lung on the other side. The deer dropped in it's tracks on the spot.
4. .223 55gr. varmint home load 3200 fps , ground hunting strait into the lungs , deer dropped like a rock. No exit.
5. .243 70gr. varmint home load 3500 fps , ground hunting strait into the lungs , deer dropped like a rock . No exit.
6. .357 pistol 158gr.HP, tree hunting entrance high in lung exit low in lung. deer run 60 yards.
"Oh" , this list could go on for a long time ...

Point is , the only one-shot-drops I've ever seen have been spine shots or Varmint (exploding) projectiles. Either one works but the Varmint requires less accuracy.
At least with people ... the threat of getting shot might end a situation ?

One more : 45cal-RN-220gr. Muzzle loader rifle , lung shot , dropped like a rock, lungs came out like lumpy gravy !
