Been in on 117 bear kills. Brown grizzly and black bears nice got stories I've forgotten. Very lucky to be a hunting guide in alaska specializing in bears.
Best advice I can give you is don't believe everything you read about bear hunting.
Very few bears die hard. .30-'06 is an awesome bear gun for any bear.
Books aren't usually from very experienced bear people.
My website has some
Photos just for kicks if Ya get bored.
