If you are a hunter or guide in Alaska, what gun and caliber would you use for stopping a charge by a Brown bear or Grizzley?
The question is about a stopping caliber. Phil Shoemaker uses a 458 WinMag routinely, but has also utilized other calibers, .375 and up. As far as handguns, he carries a .357 and recommends firing it into the ground in front of the bear as you vacate its proximity. It won't stop a charge.
