Find a mauser or pre 64 winchester action and go with something other than the 308. Spice it up a little and turn it into a 338 federal. I love mine and think it's got the extra bit of punch over the 308 that makes it more efficient for elk, bear, or hogs (excellent for both mule and white tail as well). If you don't handload though, go with the 308 or an -06. You can always rebarrel in the future if you want something with a little more kick.
Want a quick and inexpensive call for Moose? Take an empty 32 ounce coffee can, and make a small slit in the bottom, only about a quarter inch. Then, take one of those really big red rubber bands, the ones that go around big folders. Cut the rubber band to make one long piece.
Now, thread one end of the band and tie a knot on the outside of the can so it won't pull through. Cut the band off on the other side so it is even with the top of the can.
Now, wet your finger,...
