Will a 357 Magnum stop a grizzly bear?
Asked by: Dr. Faye Jacobs Sr. | Last update: July 2, 2026Score: 5/5 (53 votes)
Yes, a .357 Magnum can stop a grizzly bear, but it is generally considered marginal for that purpose. While it has enough power and penetration to kill a grizzly—especially with 158–180 grain hard-cast or flatnose bullets—it lacks the stopping power of heavier calibers like the .44 Magnum, and requires precise, expert shot placement under immense stress.
Is a 357 more powerful than a 10mm?
