The Swedes take many full size moose and Elk size animale with the 6.5x55. They would be suprised as hell to find out that they only shoot calf size animals. I have shot a lot of big game animals with the Swedish Mauser but thats a different topic from the 270 WSM Which by the way is an excellent all around big game rifle based just on what its smaller cousin the 270 Win. has done.
