I' m going to disagree that the .454Cassul can do everything the .480 can do and better, it can' t, it shoots comparably accuracy wise, and dead is dead, of course, but in energy and trajectory, the .480 Ruger wins out. HOWEVER, it' s kind of like comparing the .30-06 and the .300win mag, or the .270win and the .308win, they are so close that in any hunting application, you' ll never notice the difference. What matters to me is that the .480Ruger kicks so differently, it' s just like their ads claimed two years ago, a good solid shove as opposed to a sharp kick as found in the cassul, with ear protection, I can shoot the .480R a lot longer without gloves on than I could my .454C, of course, it costs me more. Also important is that there are still very few loadings available for the .480R, which if you handroll isn' t important. Also, there is no ' little brother' round that can be loaded in the .480R, so cheap and easy practice isn' t an option as in the .454C, good .45LC rounds through the .454 wheel would be great for taking deer with your moose gun.
Hope that helps a bit, if you' re still looking to get a new gun, the .44mag you' ve got would be fine, it' s just a shorter range basically.
You could always get a .45-70 from MR like mine!! [8D]
