YELLOWSTONE NATIONAL PARK, Wyo. — A killer grizzly is roaming Yellowstone National Park’s backcountry after mauling a man who apparently surprised the female bear and its cubs while hiking with his wife, in the park’s first fatal grizzly attack in 25 years.Okay, this is rare--the first fatal grizzly bear attack in Yellowstone since 1996. But who wants to be the rare exception? The next time I visit Yellowstone, I will have my .44 Magnum revolver with me, loaded with the 240 grain solids. This is not the ideal choice for grizzly bear self-defense, but it isn't like you can carry hand grenades or one megawatt lasers.
UPDATE: I mentioned a government report in the comments. The full citation is William R. Meehan and John Thilenius, Safety in Bear Country: Protective Measures and Bullet Performance at Short Range, Gen. Tech. Rep. PNW-152, Portland, OR, U..S. Department of Agriculture, Forest Service. I have a copy at home; I should try and find it and scan it in, since it does not seem to online anywhere.
UPDATE 2: Yes it is online! And they refer to .30-06 as a "small caliber rifle."
