RE: 400 yard shots at elk????
My .338 RUM could certianly shoot accurately at 400 yards with no wind, alas....I cannot.
However, hunting an elk with a .25-06 is not exactly smart in my book either. Sometimes I wonder what guys consider "hunting". I guess if you road hunt and plan on shooting an animal within 1/2 of a road, and making short shots caliber may not be all that important.
As for me, when the airplane drops you off, you are on your own for ten days. I sleep with my rifle loaded in case of bears, my rilfe may be called upon to save my life, THAT is not an exaggeration, it's the truth. And I when I shoot a moose, I want him down NOW!. Anyone who lauds the greatness of small caliber rifles on big animals like elk or bear has never had to carry them out apiece at a time from a muskeg that sinks you up to your ankles or a canyon that takes you four hours to get out of.
