I've hunted with and shot various 7x57's since my early 20's, having read too much Jack O'Connor and W.D.M. Bell as a kid. No animal has ever required a second shot and most went down in their tracks. Consistently ringing an 8" gong at 300 yards is no trick with my Ruger no. 1A. While not a vintage gun, it is a classic. Over the years, I've used everything from the .22 Hornet (behind the ear bullet placement)to the 45-70 including the magnums during my high velocity addiction. I keep coming back to the 7x57 and sometimes a 25-06. Current love is a Ruger 77 RSI mannlicher in .250 Savage.
