You guys are so hung up over the fact that a cartridge has to do something better than another one.
No cartridge needs to do anyhting more than be fun for someone to justify it's existence.
Isn't THAT the whole point behind different cartridges: I.e. that one is designed for a specific purpose which it can do better than another???
I sure as heck think that a .375 can bring down a kodiak a hell of a lot better than a .22 lr.
