I must protest that you are leaving out the smaller centerfire calibers, like .17 and .223 on the small end, and loads of calibers up to and including nuclear weapons on the high end. Of course all of these calibers can kill a deer, but each one does it in a little different way. For instance, whitetail meat hunters might not want to carry a .375 H&H in case a buck pops out of the brush at 15 yards, while a lion hunter might be wise to pack something heavier than the .243 just in case the lion decides Mr. Bushman is a threat when he unexpectedly steps on a dry twig at 15 yards.
Besides, like Dave says, you are taking all the fun out of having a favorite caliber! Seriously, I do think we sometimes get carried away on posts about the "right" caliber when many will get the job done. But I do think it is fun sometimes just to have a friendly chat about the pros and cons of different scenarios.
