I always like to revert back to the 30-06. Now, I'm not that old, but I cannot shake it. I am primarily a whitetail hunter, although I do hunt bears and am hunting in the west. I have almost all of the Weatherby cartridges covered in my gun safe, I've got 3 different 6.5 cartridges, wait, no...4, and I think they are spectacular for whitetail deer. In fact, I think the 6.5cm is as good as a cartridge will ever be for our medium sized southern whitetail, and serves well in timber stands as well as bean fields and creek bottoms, and kills deer dead when you hit them correctly, but no matter how many rifles I own, I grab my 30/06 more than anything else. That is probably the oldest big game cartridge I own, and I'm not even shooting AI. It just works. It kills deer like magic. It is a no fuss option that you never have to think about. It is remarkable to me how much they got right with it, well over 100 years ago, and then Roy Weatherby showed up 30 years later and made cartridges in his basement before color television that the best rocket engineers are still chasing today. Cartridge innovation has not gone through an actual major innovation since Roy Weatherby.
