An 180 gr hardcast bullet in a .357 mag is as hard as you can hit. Problem is that that is not as hard as even a light .44 mag. If that's a big bear, you may be on the light side.
The Buffalo Bore .357 180 gr hard cast full power rounds have approximately the same energy as the Buffalo Bore .44 240 gr lower recoiling rounds. I agree that a full power .44 magnum would be a better choice for brown bear or grizzly bear but those BB .357 hardcast bullets pack a tremendous punch and could probably get the job done.
+1 on this line of thinking. Back when first I used to carry a bear gun, it was a .41 mag, and remains so to this day, unless it's Alaska, then a .454 Casull FA gets the nod. But, my little brother only had a Ruger Security Six, and he used to backpack with my wife and I. So, we went to the range and worked up and hottest load for his Ruger, using a very hard cast 180 Keith type bullet, and as much Blue Dot as was safe and practical in his specific Ruger. It kicked a good bit, but was fairly accurate, and my Bro was very happy with it. For a .357, it hit hard, and though he never had to shoot a bear to see how it would work, he felt safer carrying it. For what it's worth.... Take care, and God Bless!
