Because you included elk and moose, my first pick would be a 45.70, .450 Marlin, or .444, with the 45.70 my first pick because of the availablility of a wide range of ammo from cowboy loads to garrets and everything in between.
The .35 Remington is a great choice and would work for elk and moose, but would limit the range, but hey, the big bores arn't really known as long range rifles either,and there are several members who shoot 200 yards and more with the big bores.......
I'm certain that there have been many elk and moose killed with the 30.30 but the big bores would be a better choice IMO.
The 30.30 is relatively inexpensive to shoot compared to the rest even if handloading and if your wanting to shoot alot and have a limited budget then a 30.30 would be the round for you.
