So,what does the .308 Winchester that a 8x57 Mauser won't do?
Let's throw in all the aspects of shooting..
hunting.. target...self-defense...sniping?
rifle,
NOTHING if the 8x57mm Mauser is loaded as it is factory-loaded in Europe.
(In fact the 8x57mm in some European loadings, exceeds the .30-06.)
US ammo companies have always down-loaded the 8mm Mauser, so that it could be used in some of the old/weak rifles. = That said, the 8x57mm as loaded in the USA is still a more than adequate deer cartridge.
(The BIGGEST WT "head" that I've ever seen was killed at 150+ M by a man from Upshur County, TX in the 1970s.)
yours, tex
