That’s where I landed. i figured better odds of 3-5 and 2 on target with a 10mm recoil vs 1, maybe 2 out of a revolver and 1 on target with massive recoil if I didn’t want to carry a very long barrel.
The round size you’d need to drop a bear quick basically implies you should hike with a rifle. So if you can’t do a single shot approach that makes sense (ie hike with a rifle), multiple shots with lower recoil and suitable bear load seemed logical. Then YouTube Alaska guy did all the ballistic pros/cons too.
