I think people overestimate the power of a shotgun due to the big hole in the barrel, and the healthy thump to the shoulder. In real terms, power/terminal performance is on par with the more powerful revolvers. That's not a bad thing, but a reality check.
I just don't understand giving up the power and accuracy of a rifle to take a shotgun. A medium to large bore rifle with good expanding bullets will create a fist sized wound channel clear through the biggest bear.
