You are exactly right. A good friend and life long Alaska outfitter tells every hunter behind the shoulder then start breaking shoulders.Bears aren't nearly as tough as people make them out to be. This myth of toughness comes directly from shooting shoulders.
1-Don't shoot their shoulders there's no vitals there. Made that mistake many times they are quite hard to kill when you "anchor" both shoulders and do little damage to their vitals. They also don't hemorage a bunch from shoulders shots due to the coat and fat.
2-Shoot them in the vitals with a fragmenting bullet and they die really quick. Bonded or copper bullets are less effective at this
After you kill your bear examine how it's built and how fragile their vitals are
