Speaking as someone who has followed this closely as the grizzly aka Brown Bear population up here is pervasive (and the following deals withe Brown, not black bears which should be deal with differently)
1. Bear spray is your friend (thats really the first 11)
12. You are better off playing dead
13. The best shotgun load I worked with (did not have to use but the party Chief set the load) was 4 rounds of double O buck and a slug (with spare slugs in the kit). You are not going to kill a grizzly quickly with a shotgun slug, you can blind him and distract him and the OO buck is your best chance (or next size down). Slug was to kill him
14. Any gun you carry should have hard cast lead bullets.
15. A pistol you might as well shoot yourself with.
16. I have seen some evidence that massive trauma will kill one, twice from high capacity 9mm pistol (wielded by tow different idiots who lived) and once with an AK74. One reported incident of a 45 acp 9 shot, but I did not fully trust the person telling the story.
If you have ever had the dubious luck to see a grizzly move (in person, not on TV) then you will truly know terror, they are insanely quick. The times I have they moved away, thank you very much.
As someone noted, one shot from a bolt action is all you are going to get one shot off if you are lucky and you better have nerves of steel. A lot easier to talk it than do it.
