Quick Answer
In general, the minimum caliber for hunting brown bears is considered to be .40 caliber, but .375 caliber is often recommended for its added stopping power and effectiveness. For handgun hunting, a .454 Casull or .460 S&W is typically considered the minimum for taking down brown bears.
Handheld Firearms for Brown Bear Hunting
When it comes to handgun hunting for brown bears, you’re looking for a heavy revolver capable of delivering a large caliber bullet with enough kinetic energy to take down the bear quickly. The .454 Casull and .460 S&W are two popular choices for this purpose. These heavy revolvers usually weigh in excess of 40 ounces, with some models approaching 60 ounces. The .454 Casull, for example, is known for its 255-grain lead bullets traveling at 1,800 feet per second, while the .460 S&W can propel a 300-grain lead bullet at 1,950 feet per second. Both of these cartridges offer more than enough kinetic energy to take down a brown bear.
Backup Sidearms
When hunting brown bears, a backup sidearm is crucial in case your primary handgun fails or is otherwise unavailable. Look for a reliable and compact handgun in a caliber that’s capable of delivering a quick and humane kill. Some popular backup sidearms for bear hunting include the S&W Model 10 in .38 Special, the Ruger SP101 in .357 Magnum, and the Glock 19 in 9mm. These handguns are all compact and reliable, making them great choices for a backup sidearm. However, keep in mind that even with a powerful backup sidearm, you may still need to use multiple rounds to take down a brown bear. A well-placed shot from your primary handgun is often the best option.
