As an eastern guy who has hunted Moose a number of times but never hunted Elk (although I plan to ), I had always led to believe Elk were tougher to bring down than Moose and you need at least a 300 mag. Many of the gunwriters touted the various 338 mags as perfect I just accepted it because I didn't know. Then I started watching Best of the West on TV and those guys were doing some crazy things with the 7mm Rem. mag. I joined the CF and John Burns is doing those same things with a .264 mag. Thanks to them I have a different perspective and when I finally get around to Elk hunting I won't follow the eastern hype and go straight to a .300 mag. Whatever I do take will probably start with a 2. I don't shoot long range but I feel there is a lot to be gleaned from those who do.
