>>352030The gif is the cleaner way to kill a game, but the brain is hard to locate, the head move all the time, the skull is hard and will deviate the bullet if it is not exactly perpendicular to the skull.
You will have one instant death for 10 or 20 atrocious, very long agony in unimaginable pain.
On the other hand, lungs are easy to get and with a decent caliber the game will choke in its own blood in a minute. This is one minute of inhumane agony, but still only one. It is the best we can do.
