I'll have to go along with the Alaskian Game Dept. on caliber recommendations.

Too many hunters have read all about "dangerous game" in the hunting rags or watched so many movies, they think you can't hunt Africa or Alaska with anything less than a 375 H&H or 458 magnum. If I were going on a hunt that I knew would have me facing charging grizzlies at 20 steps, sure I'd pack a .458, that's no where typical bear hunting conditions.
