So this is what it looked like out of the box.
We started off using the T-Rex for science and testing wound channels for different rounds.
Then we just shot him to hell.
That sreak going through the T-Rex is from my Smith and Wesson short barrel revolver with Hornaday .357 defensive ammunition.
I think it's safe to say that the bullet expanded pretty well on impact; and, given the shape of the wound toward the exit hole, the bullet probably did a good job of slowing down before popping out.
Seems like a good defensive round.
