Different round. 8 X 57 and 7 X 57 are both very good hunting rounds. Both are loaded by Hornady, Winchester, Federal, and Remington, to name only some of the manufacturers that carry it. Most factory loadings are very much in the safe range of pressures out of fear that some older, tired military weapons exist out there.
Either round in a modern firearm can be loaded to very nice hunting rounds with a variety of purposes.
