Please explain the big advantages of the .308 over the 7x57. I have used both cartridges a lot and have a hard time seeing any difference in field results, recoil, etc.
I can appreciate that the .308 has more factory loads available, at somewhat higher velocities. Also that it is generally slightly more accurate, which I believe is mostly due to more consistent throat dimensions. We could also argue that it fits in a short action, saving us maybe a 1/4 of a pound.
