Not entirely exclusive.
I've spent many of the last 20 years on assignment in Alaska, specifically the Fairbanks and Anchorage locations. While the 12 gauge slug gun may indeed be a favorite of guides there, more than a few guides and bush pilots I met packed the Marlin 1895 Guide Gun in .45-70. I would wager that Ken at WildWestGuns does an alright local business in leverguns chambered for .45-70 and better, also.
Only if you're loading BP or commercial powderpuff loads for a Trapdoor Springfield. I run 405gr Beartooth hardcast rounds at 2,100fps through my Ruger #1, and some of the commercially-available Level II Marlin/Winchester/Sharps loads like Buffalo Bore and Garrett are closer to the latter than the former.
Don't get me wrong, 12 gauge and 10 gauge slugs are great for big bears. 30mm GAU-8 rounds are even better, and nobody's gonna argue that the 120mm M1A2 smoothbore would make short work of a pissed-off grizzly bear. Give me a Marlin Guide Gun, and either Level II handloads, Buffalo Bore or Garrett Hammerhead commercial loads, and I'll be just fine.
In Alaska, bear distances in which your life is in peril is measured in feet. Use what the guides up there use for backup (unless it's a .375 H&H), and it ain't no stinkin' .45-70.

If a .45-70throws a 405 slug @ 1,300 and a 12 gauge throws a 437 @ 1,900, guess which one wins.
