I think there are a lot of cartridges that deserve more accolades than they get, 280 as mentioned, as well as a lot of other older cartridges, 358 Win is another already mentioned, but in my opinion the most under rated of all, by everyone who has never hunted with one is the 350 Rem Mag. I too was guilty of dismissing it as a joke until I got a Mod 7 KS on a trade and did a little hunting with it, I was VERY impressed with this little cartridge and I must say it kills all out of proportion to it's paper numbers. My 350 is now my constant spring companion and resides in a little niche in my camper all summer as a "just in case" gun. This little rifle and cartridge has derailed double digits in black bears and I don't recall ever shooting one twice, from point blank to 300 mtrs!!!!
