High Noon,
A man with your education and income should be able to have several rifles.
If you reload your own ammunition the rifle instantly becomes very versatile.
For example I bought a 375 H&H magnum for my son so that he could come bear hunting with me.
Now I use it for deer with either a Sierra 200 gr.
or a 220 gr Hornady @ 2,200 fps.
Very dramatic killer on deer.
But with 270 grain bullets at 2,700 fps it is a lot better suited for African big five. My advice is to think less about rifles and more about reloading.
A Handloaded 220 gr. NOSLER in a 30-06 would be big enough for what you need in Alaska IMO.
A 35 Whelen with 250 grain bullets at 2,400 fps is nothing to sneeze at either.
You have a very versatile rifle once you get away from factory loads.
A 225 gr Partition @ 2,700 fps is "flatter shooting" than most people can utilize.

I like to do my hunting BEFORE I pull the trigger!
There is only one kind of dead, but there are many different kinds of wounded.
