Did some browsing and found this:
Grizzly, Brown, and Polar bears
On the North American continent, where I live, dangerous game is rather thin on the ground. Most species live in places far removed from major metropolitan areas. This is particularly true of the most glamorous species, the great bears: grizzly, brown, and polar. They are hunted primarily in Canada and Alaska, although relatively small populations of grizzly bears can be found in some of the Western United States. Adding to the difficulty of the hunt is the fact that the great bears are protected in many areas. I believe that polar bears are protected almost everywhere.
These great bears are the largest predators on earth, the top of the food chain wherever they live, and belligerent by nature. They have fair eyesight and excellent hearing and sense of smell. They are armed with fearsome fangs, huge claws and are immensely strong. They can move silently in thick country and yet easily outrun a man. Adults are generally too large to climb trees. They must never be taken lightly and should not be approached except under favorable conditions.
Polar bears are denizens of the far north. Their normal prey is seals and (in the appropriate season) bird's eggs and fledglings, but they will kill and eat pretty much anything they can stalk and catch, including people. They are strong swimmers, seemingly immune to Arctic water temperatures. The great white bears are unchallenged in the wastelands they inhabit, and so are generally afraid of nothing.
An average male polar bear will scale about 900 pounds, a very large specimen1100 pounds, and an exceptional individual can grow to 1550 pounds. Even females, which are generally smaller than males, have been known to weigh as much as 900 pounds.
Grizzly and Brown bears are actually the same species. The division is geographical, not genetic. On the coast they are brown bears, and inland they are grizzly bears. Abundant forage, particularly the great Alaskan salmon runs, provide the opportunity for the coastal brown bears to attain prodigious size. An adult grizzly might attain a weight of 700 pounds (400 pounds for a female). A very large brown bear might weigh 1000 pounds, and an exceptional example can scale 1600+ pounds. That is bigger than most buffalo, which in prehistoric times were preyed upon by grizzly bears.
Both grizzly and brown bears are temperamental, ferocious, and can be very unpredictable. They are also intelligent and curious. Do not underestimate these creatures. It is recommended that non-residents hunt with an experienced guide.
Use plenty of rifle when hunting any of the great bears. About 3000 ft. lbs. of muzzle energy (ME) or more is suggested. The various 7mm Magnums and the .30-06 with heavy bullets of high sectional density (SD) are the minimum recommended calibers. Better are numbers such as the .338-06, .35 Whelen, .405 Winchester, .450 Marlin, .45-70 (with heavy loads) and the various .300 and 8mm belted magnums. Powerful medium bores including the .338 Winchester Magnum, .340 Weatherby Magnum, .350 Remington Magnum, .358 Norma Magnum, 9.3x62, 9.3x64, 9.3x74, and .375 H&H Magnum are ideal. I have read that the most popular caliber used by Alaskan guides to "back-up" their clients is the .338 Win. Mag.
