Your reseach is the best answer for you and your choice !
Use other's opinions as just that - opinions........................
When I wanted a rifle to fit those needs; I brought a Sako A7 Stainless in 7MM Rem. Mag.

A classic saying for the 7MM RM is;
Shoots as flat as a .270, and hits as hard as a .30-06.
If you're including brown bears, then that's why I brought a .338 WM also !
