7x64, 7mm-06, 280 Remington, nothing at all between. My German friend uses the plastic stocked Steyr Mannlicher Professional 7x64 as his go to rifle for general hunting.

Slightly but not much over the 7x57 or 7mm-08 and not quite up to the 7mm Magnums but they're all excellent game cartridges and that says it for the 7x64.
