Hard to argue with a proven rifle. I'm a huge 70 fan and run a .270 most of the time. With that being said if I were in your shoes I might take my Winchester classic 70 in 300 mag, but I'm sure your plan will work out fine.
I would probably try to keep the speed up on those Barnes and opt for the 130 over the 150. In a Partition I would take the 150 since moose is on the menu. But I've never killed one so my suggestion isn't worth much.
Sounds like the hunt is going to be awesome!
