Been there, done that. If I'm hunting where there's grizz, I'll want a stout bullet.
As it's been mentioned, when it happens, it happens fast and your more in a wing shooting mode than "pickin a spot."
8 1/2 brown bear at ~ 5 yards, coming like a freight train. 300 Weatherby with a Barnes X; don't remember if it was a 165/168 or a 180 grain through the shoulder. First shot knocked her down, rolled her downhill a bit which I think saved me/us (we were standing on a small knoll). I jammed my rifle somehow, cleared it and knocked her down for good at about 50 yards. Did I mention my partner froze?
My 2 cents.
