Bowcat, both MagniAesir and I hunt in British Columbia, Canada, he for more than 30 years, and I for more than 50. Black bears and cougars are common throughout the province, and grizzlies in most of it, especially where we hunt moose and elk, and more recently, they've moved into our local deer hunting areas, within 50 miles of our homes. Though neither of us has trophy hunted the carnivores, I have meat hunted blacks, and had to take down a charging grizz on one occasion. I was using the ubiquitous 30-06 at the time, and though it took more than 1 shot, that bear is now a beautiful rug, and I'm still here to tell you about it. BTW, both of us have at least a decade of bow hunting experience, as well. Two close friends have also taken grizzly under similar circumstances over the years, and both were downed with one shot, using a .270, and a wildcat 7mm-308, so I think that MagniAesir's statement that that magnums, or 'elephant guns" are not necessary to take the type specimen can stand, from my perspective of experience with large, dangerous game.
