Tex, A bullet is designed to kill with shock, not how big a hole it makes in the game. A perfect match is the combination of the right caliber and correct bullet choice for a particular hunting situation. In a perfect scenario, the bullet expands on contact with the animal. Upon impact, the energy or shock of the impact causes massive shock to the animal causing an extreme accelleration of blood to the heart and brain. This renders the game instantly unconscious. If the correct type bullet was selected the bullet should be found just under the skin on the opposite side of the impact. All the bullets energy was expended on the target. Maximum shock and energy expended on the target. The damage caused by the bullet itself is to inflict damage to the internal parts to assure that the game will not regain consciousness. This is a perfect scenario. Distance, obstructions in the path of the bullet, wind, and most important is the skill of the shooter make an accurate shot that is critical for a quick, humane kill.
Good Hunting...
