I think you'll be cursing the day you were born if you ever have to drag 30 pounds of rifle through a swamp looking for moose. Are you going to try and shoot that thing off the shoulder or do you figure you'll just find them out in a pasture where you can just set up a bipod?
You're not going to hunt in the lower 48 because you can go through your whole life without ever being drawn for moose. You can try Canada but I doubt they'll let you in the country with a .50 bmg.
That leaves Alaska where toting a rifle that size through muskeg and "hippy-heads" and alder jungles is ....not going to be much fun.
