I hear ya! That thing weighs 12 pounds. I'd rather be toting around my 6 pound .243, but that long range gun has more than twice the reach of the .243. It's easier to walk up to them without the rifle when they're dead than stalk after them with the rifle when they are alive!
Although after my experience this year, I'm thinking of finding a lightweight rifle that can shoot to 600-700 yds if required. Something in the 6# weight class with scope. I know recoil won't be pleasant, but I can live with it for one or 2 shots on game.
