Once upon a time, many years ago I was in a gun shop in East Central Wisconsin when a guy came in with the sweetest Remington 700 in 30-06 that I had seen in awhile. It was midweek during the annual Wisconsin deer season. While I was there to buy readily available .308 ammo (My preferred round at the time and still may be so many years later) Anyway he wanted to trade in the 30-06 for a 458 Win Mag stating that the
30-06 was inadequate for hunting White Tail Deer. The owner of the place, who was a friend looked at the guy as if he was crazy and asked how he thought his 30-06 was deficient. He said that he shot a magnificent (so he says) buck three times and the buck did not fall and in fact ran off without leaving a blood trail. He wanted the .458 mag because he heard it would knock down anything. To make a long story short, he did buy a Model 70 in 458 Win Mag, at the end of the season he had still not tagged out and blamed it on those Wisconsin Whitetails who simply refused to die. We all kind of figured that one has to hit the deer before one can kill a deer and a .458 Win Mag was not the cartridge to do it with. I guess the point that I am trying to make here is that, " Bigger isn't necessarily better."
