I’m with ejo; go 30-06 or smaller, use a good bullet, stalk closer.
My M28 in 270 wsm worked well on a black bear in SE Alaska, and I wouldn’t hesitate to use it on sheep or griz. Considering how close we had to spot and stalk to get him, I sure didn't need any magnum, I am no longer a fan of magnums in general. If you don’t mind the negatives, more power to you. I personally wouldn’t want more than a 7 mag or 270 wsm in a NULA. I wished I could snap my fingers and turn my model 28 magnum into a model 24 270.
Whatever you choose, they are great rifles, so pick something you will want to shoot a lot and keep forever! With the right bullet and shot placement, the choice doesn't matter so much, it just needs to turn your crank.
