Pretty much everything I heard about if you don't hit them good with the shot it's gonna take quite a few bullets to drop them 6-7 hits as they run and most of those are from a 375 H&H .I was told by my GuideNo such thing as overkill in the midst of sows with cubs.
Simplest solution is to have some heavy for caliber, well constructed bullets, ready to go when your searching for animalsI took the mountain goat in my profile photo on Kodiak in 2018. The outfitter told me to bring the largest caliber rifle I was comfortable with, for the goats will suck up lead and you want something bigger to deal with bears if they become an issue. The outfitter carried a 325 WSM and the 2 assistant guides carried 300 WM. Everyone, including myself had a 45 or 10mm handgun, also. I purchased a 338 LM for this hunt. Never saw a bear, but our halfway point (3.5 hours of the 7 hour hike) to our spike camp reeked of bear. So, they obviously were traveling in the same places we were. You can't be too prepared for big bears. Have a great hunt.
I hike Pole Bridge Montana near glacier yearly, big time grizzly country, my two forms of survival should an attack occur is #1 a dog that can smell a bear a mile away, and not afraid to distract a bear , and if that fails I carry a lightweight Mossberg Maverick 88 top folder 12 ga pump, first shot is Dixie tri ball will stop any land animal in it's tracks more than likely.I'll be hunting deer on Kodiak this summer. Thinking my 338 Edge is a bit overkill for a deer but having the firepower for "just in case" has it's appeal. Other option I have is 6.5 Creed....454 Casull will be on my chest.
Which would you take....Edge or 6.5 ?
Don't worry about any predator on planet earth, only one ,Homo Sapiens, by far the most dangerous and unpredictable.,10 grizzlies encountered in 12 years near Glacier,private land and no mishaps,however I stand by what I say a well trained dog I would never be without when in that wilderness, surprise attacks is what gets you killed. And that's an impossibility with the dogs that have accompanied us. This female will go with us in September for a week. Attack, obedience,tracking, quiet as a mouse but can hear a mouse, fart and smell one at uncanny distances, trained in Slovakia.The dog sat in the car for 10 minutes while I was outside the car talking to a local cop about her, people walking by asked if they could pet her, go ahead she's fine. TRAINING<BREEDING<BRAINS AND ABILITY, is all we keep.The first time i hunted Kodiak i took a 300 mag. Once i saw what it was all about i took a 260AI on my next hunt. I've lived there the past 4 years. Mostly hunting with a 308. Last year i took a grizz and 2 deer. I shot the deer with my 340 Wby mostly because it was shooting good. I hunted an area that had no bears. I have a goat hunt next month. I'll probably take my 308 but load some 168 TTSXs. I don't worry about bears. But I'm prepared to deal with them.
I have a spring brown bear permit for 3 saints unit. Either the 340 or 9.3 gets the nod.
