19 years in Alaska hunting bears and worrying about all the details...I have carried a few .416s a 340 WBY but the two times I tagged out were while doing other things with my ever present 6.5 lb ,06. A 125gr X bullet on my first kill a 180 A frame followed instantly by another...
I just shoot and carry the WBY now. Just like it.
250 RN @2950 it is as accurate as my F-Class rifle.
My guide friend said to me..."your problem is you fall in love with the bear, then won't kill it" I do seem to find an excuse to just let THAT one walk.
