Yes I know where you are coming from and agree we never really know the full or true story. I suppose in the context of how a cartridge performs it probably matters not if the animals are shot from a vehicle in terms of bullet performance. Much of African hunting seems to be waiting until the animal is stationary and presents a good shot before taking it off the sticks, much the same as if shooting from a vehicle.

Of course in most countries, and certainly if you are paying for a trophy hunt, you would want to hold off until you get as close to the perfect shot as possible. It is countries like NZ, were we have no game rules or laws as such i.e. no season, no limit, no restrictions on animal age, sex, etc. where you can take long range shots, running game shots or any shot you like using any cartridge you like. This usually sorts out the men from the boys in terms of cartridge and and hunters too. We also do not a culture of class or ethics when hunting as such i.e. if you miss or wound an animal and don't recover it or get an animal and only take the back straps because it's too far to carry the rest, nobody sees this as an issue, it is just part of hunting to us.
Most I've ever hunted with here if they have a miss or stuff up on an animal just say f....k and move on. Thank god we do not have the stiff upper lip "it not the thing to do old chap" mentality.
