What do you think about the gun writers that say the S&W 500 with it 2600 muzzle energy it capable killing anything in North America,but in next month's issue they will say that that a 270,30-06(both have much more muzzle energy than the S&W 500 and tons more down range enery) is too small to feel safe with in big bear country?If a griz were bearing down on me I would feel much better with my 270 or 30-06.
