The suitability of the .308 Winchester cartridge for defense against grizzly bears is a frequently debated topic among hunters and outdoor enthusiasts. This caliber is generally considered adequate for most North American big game, but the immense size, strength, and aggressive potential of grizzly bears necessitate careful consideration of cartridge effectiveness. A .308, while capable of inflicting lethal damage, might not deliver the stopping power required in a close-range confrontation with a grizzly. Factors such as bullet weight, construction, and shot placement become paramount when discussing its viability.
Selecting an appropriate caliber for grizzly bear defense is crucial for ensuring both personal safety and ethical hunting practices. An underpowered round can lead to a wounded, dangerous animal and increase the risk of injury or death for the hunter. Historically, larger caliber rifles like the .338 Winchester Magnum, .375 Holland & Holland Magnum, and even larger bore rifles have been preferred for their greater stopping power. The effectiveness of any caliber, however, is heavily reliant on hunter skill and accuracy under duress.
