The second deer has a bigger exit wound, on shoulder I presume, and that might be some shoulder bone exit effects too:
The third deer moved as the trigger broke and looks like it nearly got cut in half, maybe the bullet motivated a big chunk of spine toward exit:
Entry points and range of impact would be interesting to know. I guess all the entry wounds look the same, about caliber size, tidy holes in hide, like the one on the deer I clobbered with a Buffalo Bore 400-gr TSX at about 2350 fps MV.
The 450-gr TSX at +2400 fps of Sir Jerry's handload will expand better than a lesser sectional density bullet of same velocity. Even mo'better if both heavier for caliber AND faster at impact and same TSX-type HP.
