Now THAT is a bullet no two ways about it. I find that the Lee .452-300 RF out of my 454, is plenty of lead for anything I plan to hunt. I don't even load it to top end and it still rocks.
I totally understand the "BIG" bore attraction as well, but I have to have a use for what I put in the safe, and unless the hogs here get a LOT bigger, or a LOT tougher, I simply can't justify anything bigger than what I already have.
