If the rifle will take the 156 and 160 grain round nose bullets you would be in the same class or better as the 6.5X54 Mann/Scho.
The "256 Mannlicher" was known 100 years ago for it's exceptional penetration with those kind of bullets.
So yes you would have the capability of making kills on big bears.
But you better shoot well. Big bears die as easily as anything, if you break their spines or brain them, and the 160 gr bullets will go deep enough to kill with lung shots.
But if you were facing a mean bear, where the bear was the hunter and you were responding, you'd better keep cool and shoot REAL well.
