Mr. Murphy is alive and well in the hunting fields as well. But you can still do your part by getting enough practice under field shooting conditions, and by using a good bullet. Yes, as you said, any bullet can go astray inside an animal, but I think you'd have to agree that some are more reliable than others, and are less likely to deviate from their course. For example, if you were hunting Gemsbok, would you be inclined to use a Nosler Ballistic Tip, or a Barnse X?
