“Umph” isn’t a wounding mechanism and only exists in your imagination. Animals die by destroyed tissue, and bullets destroy tissue by penetrating, tearing, crushing, stretching, and bruising. None of that has anything to do with “umph”.
You would be light years ahead of you slow down, read the thread below for how and why bullets kill, and then start asking questions.

That’s isn’t for you to choose a 223, it’s because there is more legit information in that single thread on how animals die, how bullets kill, and why just about everything that is “common knowledge” is factually wrong.
