There's buckshot and then there's buckshot.
I don't know if #0000 will stop a grizzly, (I am guessing it will), but there is a huge difference between it and #00 Buck
And there are quite a few documented reports of people in Alaska repelling bears with #00 Buck. The ones that I've read - they've been coming in the house when they've been shot, and the shot wounded but didn't kill the animal, which had to be tracked down and destroyed.
If you don't think #0000 will do the job, there is always tri-ball.
I would definately sound a note of caution though. If I remember the last few incidents where people shot bears and it didn't involve the ber actually coming into the home - there were fairly resource intensive investigations done to determine if charges could be filed against the shooters. I would think it would turn out badly if it looked like you went gunning for bears. Last year, June 1st, in Denali National Park a hiker shot a charging grizzly with a .45. It garnered a fair amount of media attention and he had to wait until July 30th to find out that no charges would be filed against him. And there were quite a few people inside the National Park Service and without - that wanted to see some kind of charge, any charge, filed against the hiker.
