Quick Answer
Heavier calibers are usually necessary for bear hunting scenarios involving larger grizzly or polar bears, or when hunting in areas with dense cover or where a quick, decisive shot is critical.
High-Risk Situations
When hunting grizzlies or polar bears, even with a rifle, a heavier caliber handgun can be a lifesaver. In these situations, a .454 Casull or .460 S&W revolver is ideal, as they can deliver a massive amount of kinetic energy and penetration. Aim for the heart or lungs with a 240-grain bullet at 1,800 feet per second to ensure a quick kill.
Densely Forested Areas
In densely forested areas, a heavier caliber handgun can be more effective due to the limited visibility and potential for a longer shot. With a .454 Casull or .460 S&W, a 200-grain bullet at 1,900 feet per second can expand quickly, taking out the bear’s vital organs. However, always prioritize accuracy and a clear shot over sheer firepower.
Backup Sidearm Considerations
When choosing a handgun as a backup sidearm for bear hunting, consider a heavier caliber like the .357 Magnum or .44 Magnum. While these calibers are not as effective as the .454 Casull or .460 S&W, they can still deliver a significant amount of kinetic energy. Aim for the brain or spine with a 180-grain bullet at 1,300 feet per second to ensure a quick kill. Always practice proper handgun technique and safety protocols.
