M1 or m2 ball are FMJ and the cheapest .30-06 available. FMJ will icepick through soft tissue, hydrostatic shock is a meme. That shot isn't hard to achieve for a recreational target shooter who is probably using cheap plinking ammo. There's nothing unreasonable about the claim that it was .30-06. To really have an idea you'd have to be able to look at the wound channel which is information that we will never get or be able to trust if we do.

No, even m193 and m855 that are designed to tumble or fragment don't do it reliably. 7.62x39 and 5.54x45 are both far superior in that regard.
