The standard factory slugs of olden days would be risky for deep penetration into the body of a big bear on a frontal charge, I think. Soft lead shell with the hollowed out butt half.
No reason not to use the well proven Brenneke-stlye slug, with the possibility of having to hammer a 600lb or heavier bear. They aren't prohibitively expensive.
I do think most any 12ga slug will drop 200lb bears at close range. I have to contend with the possibility of encounters with some big boars. So I prep for them. Any overkill on smaller sized bears is icing on the cake.
Even a 200lb grizzly will rip ya a new one if they make physical contact. Quicker they die, the safer and better for all involved. My scalp remains intact, I retain my good looks, and my black hair turns gray at a slowed rate.
