Hehe- "have killed" and 'should even attempt to kill' are often two things some hunters don't morally perceive; I saw a guy on a thread one time try to argue the virtues of moose hunting with a .223. Many guys will claim they are all about shot placement, but having an adequete gun to harvest game is a big part of being a responsible hunter and warden of nature IMHO.
And I'm always reminded of the fact that people used to crawl into bear dens with .22s and kill bears, and the story of the Alaskan grandma who took a bear on her front porch with a .380 or some little thing....
Can you?
