After hunting in the area you’ve described I built a 350 RM on a 600 action and used 250 grain bullets.
I think I’d be using a 35 Whelen in the cartridges you’ve covered. But I built a 375 Whelen AI that I might use too. But you can’t go wrong with the 35 Whelen IMO.

The 30-06 with good bullets would work well too.
