You folks are quite literally "armed for bear!" - LOL!
Got Weatherby? ;)
Shotgun slugs were good enough for buffalo hunter Wyatt Earp, that's good enough for me. Besides doing the job about as well, shotgun barrels hold up a lot better than those big rifles. If the range is more than a hundred yards, but under 400, I will fall back to the pistol, as did Wyatt.
