Of the hard cast variety
Depends on what is damaged. I've shot a few deer through the lungs/heart with .452 dia shotgun sabot rounds and while they have not gone far they do not drop without major bones or spine also being damaged. Bullet construction plays a big part also. Some .45 cal pistol bullets grenade at rifle velocities and they tend to disrupt the nervous system more on high lung hits but also jelly a lot more meat than I like.I think anytime you shoot a whitetail in the vital area with a 45 caliber bullet at rifle velocities you get a bang flop.
