Broey 1. You are absoluley right. I have an Uncle who worked as a professional hunter for forty years. He killed every African and North American species of game with one rifle. A 30-06 Model 70 Winchester. From fox to elephant. He owned bigger rifles but had 100 percent faith in that 30-06 and never changed anything but the bullet weight. He was however the best rifle shooter that I ever knew. I have a 6.5x55 Mauser that I would not hesitate a minute to use for all North American Big game. I shoot it well and with the 140 grain Hornady SP I have never had an animal get beyond a few yards. There are far more inferior shooters than there are inferior calibers.
