If I had to choose from my current battery, I would take my 7mmRM with 150 TTSXs and a .30-06 with 180 TTSX's as back up.
If I were to buy a new gun for such a hunt I would buy a .338 Win and shoot 225 TTSX's. Or I would sell my 7mm and buy a .300 Win and shoot the 180 or 200 TTSX.
.300 Win and .338 Win best Elk cartriges in the world (Tie!)
