I don't care what that chart says - 123gr. bullet at 2,300fps is not a 300yards Caribou round, let alone a moose and elk round at any range. That's ridiculous in my opinion. Good Lord - it's a pop gun. It is much LESS powerful than a .30/30, and generally not as accurate as a M94 lever action, either. Spray and pray with large capacity clips - carry lots.
