I agree with this 100%. I really can't rap my mind around bigger and more powerful is better. There hasn't been a large game animal in the US that hasn't been killed with a 30-30, don't get me wrong I am not recommending that anyone go hunting Grizzly Bears with a 30-30 because there are better choices. As fastdadio said a 45 Colt 300gr Ruger only +P will do the job on any big game in the US. While I'm at it my first choice in rifles would not be a Magnum. With the right bullet and with in its range my choice would be a 30-06 and I wouldn't feel under gunned. As for the 454 or 500 S&W are not on my long list of Revolvers or Lever actions to own. Sorry for the rant.
