For doubters-william "karamojo" bell killed hundreds if not thousands of elephants with perfected precision brain shot with a 7x57mm and fmj bullet. Could he have killed as many without getting killed with less skill but bigger rifle-I really don't think so. He studied until he was actual expert on bullet placement and was a marksman without peer. That's why I say it's shooters skill-not big supermags that gets the job done.
