What do they do in animals? Is there a bit of weight loss, 100% weight retention, etc.
Gotcha,
They are generally pass throughs, but in the rare event I do find them they are mushroomed out in the back side of the skin or in the ribs. But thats rare. Really rare. I have never seen one come apart in any meaningful way.
Generally they leave the chest cavity completely destroyed and have an exit wound somewhere between a golf ball and a baseball size. A few have run but leave blood trails and none lived longer than a few seconds after being shot.
That's out of a .243 but I see the same thing out of my .257 Roberts, my 6.5 Swede, and my 30-06.
