This may or may not be a fake, but I have seen this much damage from various bullets. If the bullet came thru from the other side and hit bone, it could very possibly have blown not only the remainder of the bullet but most likely bone, flesh, and skin thru causing this damage.

Also a front shot which went bad and hit the animal at a more or less type passing shot, it very well will cause that much damage.

Speaking from more than 40 yrs of hunting and using several different firearms over the years, you would be surprised what a bullet can do.

My 2 cents.
