Wow Hardcast...to each his own I guess. But both myself and my friend have dropped both elk and moose where they stood with our measly 30-06s and 180 gr Barnes bullets. And while I could possibly see someone using a 338 WM on either of these critters and the bigger bears I quite honestly don't see the need for anything larger for north american game. But like I said, to each his own and if it trips your trigger more power to you. Heck I use a .45-70 for deer which is a lot more than necessary.
