A .30 Mag with today’s bullet choices, especially with 180-220 gr .550 - .700 G1 BC along with their high SD are IMO the best NA heavy game magnum caliber that offers the most versatility that can be had. From any range, especially from 400-800 yards and properly scoped the .30 Mag combines ballistics and power that can’t be matched by a .35 way out there. The .35, while potent, can’t hang with the long range capability of the .30 Mag, mostly due to the bullet technology available in the .30 and that lacking in the non sweet spot .35. For plains and mountains on smaller game up through elk, moose and mountain grizzly you would be hard pressed to find a more shootable, potent and versatile setup for an all around NA big game rifle. The 308 Norma can push a 212 gr high BC (.660) bullet easily at 2,850 fps from a std length long action magnum bolt face, that’s some serious big game lights out, especially way out there if you’re good enough to make shots way out there. Only one man’s opinion.
