It has the punch to do it all, reach out to 800yds, excellent stopping power, hard cover penetration if needed, with only medium recoil in a small package in short actions and its READILY available around the world.
The 8x57 mauser is on par, in the US the 8mm Mauser may be exotic but here in Europe its like the 30-06, readily available and it packs hell of a punch. 196 grains @ ~ 2650 fp/s is nothing to sneeze at and recoil is not bad. Its a true do-it-all cartridge. Its downside is the rifles chambered in 8x57 are all either K98k's & G98's (OK thats not really bad) and hunting rifles.
A modern rifle in 8x57 would be awesome but the .308 is enough.
