Read the whole thread and it is an interesting one.
Which begs the question...
Why bother hunting, tracking, stopping wounded bears with anything over 30 caliber?
OR
Is there a scenario in which the over 30 cal rifle gives the hunter or guide an advantage?
While I might be willing to hunt the large bears with a sub .30 caliber rifle, I sure wouldn't want to see one in my guides hands. I've read stories of native guides backing up bear clients with .30-30's. In that situation I'd carry a .338.
This. I have no do have a dog in this fight other than having bear on my list. I would feel comfy HUNTING a bear with my 30/06, but I know I'd reach for my 9.3 in a charge/tracking situation.
I realize a charge would not allow that convenience.
