....I agree with many comments above alluding to the 357 being VERY light indeed for bear! It's not that a black bear couldn't be killed with one, a 22RF could kill a bear, BUT it is not a good choice as a dedicated bear stopper! Neither is it a wise choice as a camp stopper for PROBLEM bear! Why gamble life and limb on a MARGINAL caliber for your intended use?
....The handy little Rossi 92 replica is a fine gun from the standpoint of portability around camp, but the 44 mag or a mag pressure loaded 45 Colt chambered Rossi would be a far better choice in the little gun.Better yet a Winchester 94 Wrangler in 38/55 with hot loads (not much more beefy a carbine than the sweet little 92)would up the ante if a rowdy bear acted up. Finally the suggestions of a slug loaded shotgun really swing odds more strongly to your side of any altercation! For something really handy and lightweight look around for a Ithaca model 37 pump gun (even 20 GA would be good), or a used Franchi AL48(this gun in 20GA would be lighter than the Rossi!).These guns with modern slug loads would be sufficient for an errant grizzly up close in camp!..Good luck, and good fortune on your jaunts afield..Hope you won't need bear protection..
