In armor training. They explained for a sabot round to work correctly it had to leave the Or exit the turret. Thus sucking the crewmembers out with it. The web sight terminal ballistics research also discusses trauma based on velocity. I think smokepoles point is also valid in that the lungfield will be in a varying degree of susceptibility depending on its state of inflation upon impact. The other thing to consider in ruminants is the rumen which predominantly occupies the left abdomen and is basically inert sack of ingesta, this makes almost impervious to shock in that area.
"Sabot
Sabot rounds work like a basic arrow. They don't have any explosive power; they penetrate armor with shear momentum. The heart of the sabot round is the penetrator -- a narrow metal rod (typically depleted uranium) with a pointed nose on one end and stabilizing fins on the other. Before the round is fired, the rear part of the penetrator is attached to a propellant case, and the front part is attached to the sabot structure. The sabot's purpose is to keep the narrow penetrator centered in the wide gun barrel.
On firing, the propellant casing remains in the chamber, and the expanding gas pushes the sabot and attached penetrator down the barrel. The sabot is attached to the penetrator with relatively flimsy plastic, so it falls away as soon as the round leaves the cannon. The heavy penetrator flies through the air at high speed toward its target tank. Because of its narrow shape, the penetrator focuses its full force into a very small area, plowing straight through heavy armor. As the penetrator enters the tank, heated fragments of metal fly off in all directions, hitting anybody and anything inside.
HEAT
HEAT rounds use explosive firepower, rather than momentum, to penetrate armor. At its nose, the round has an extended impact sensor. When the impact sensor collides with a target, it ignites an explosive, which melts surrounding copper. A shape charge liner concentrates the molten metal and hot gases into a narrow blast that cuts through the armor.
The M1 also has three machine guns. It has a Browning .50-caliber M2 and a 7.62-mm M240 mounted to cupolas on the top of the turret, and another M240 mounted next to the main gun."
How any of the above relates to "stopping" or "killing" an animal with a rifle or handgun conventional bullet, I'm waiting with baited breath to find out.
I got banned on another web site for a debate that happened on this site. That's a first
