This bullet could do the job. I'm going to order some and try 'em out, not necessarily for bear, but I like the idea of having a heavy-for-caliber round for my G22 and G23 should I need to use one of them for a backup gun in a hunting situation.
I have to reiterate what I've said many, many times before, though: handguns are a poor choice of firearm for bear defense. A rifle or slug shotgun are my preference.
FWIW, though, unlike others have posted I wouldn't be
totally averse to using an XTP or GDHP 180 gr load for black bear under the circumstances you've described, but it wouldn't be my first choice. I think you should also heed what JJHack has written, above... whether you're going to be hunting bear, or defending yourself and/or your camp from bear, you really should go with a larger/heavier caliber in the .44 Mag or .45 Colt class or larger.
Using rubber bullets combined with airhorns and/or pepper spray as a deterrent to bears approaching camp is also an alternative to consider, but once the bear is in close proximity to you/your camp, especially if it's a hungry bear trying to get at your meat cache, this may not be a viable option. Gary Shelton describes several bad encounters of this type, and in his experience/opinion you need a heavy rifle or slug gun in such situations. I happen to concur with Shelton on this.
