Re: 175gr MKs vs. Wild Pigs
They are definitely thicker and they do tend to develop that thick "carapace" on their back. This doesn't make them bulletproof, but it may cause certain frangible bullets to prematurely expand and dump their energy too far from the desired location. Another thing that makes them seem harder to kill, in my opinion, is that they don't understand they've been shot and are about to die (no animal does). All they know is that something just hurt him in the spot he was standing, so he's going to run as fast as he can in the opposite direction he believes the threat came from. He'll continue to run until his brain can no longer tell his muscles to work. Even if his heart is destroyed and no longer capable of pumping blood to his brain, he should have about 8-10 seconds (maybe more) worth of oxygen left in the vessels in his brain. That's about enough oxygen to keep him running for 30 yards at least! And since his heart is not capable of pumping blood to his brain it's probably not going to pump it out of any wound (gravity gets a say so, so some does come out). That may partially explain the lack of a good blood trail. The small exit hole contributes to the lack of blood as well. It doesn't necessarily mean that the bullet didn't expand or create a sufficient wound channel. It could mean that the bullet had already transfered enough of its energy to the surrounding pig resulting in decreased velocity to the point that the wound channel was getting narrower, and merely ran out of pig. We've all seen the gelatin block wound channels, starts narrow, then creates a big cavity, and ends looking similar to the entrance channel. I've run on long enough. None of this really matters if you put the bullet (any bullet) in the right place.
