7.62 x 51 is STILL a NATO Round!In all my 55 years of hunting, I've never needed to shoot farther than about 425 yards on any game. All with a .308. Having said this, it can go farther. My personal limit is around 600 yards on it. Some game have "thicker" hide than others requiring a heavier caliber for drt reliability. And there are some game out there that may require much farther shots than I would be comfortable with using my .308. My trusty 300 wm can fit the bill for "longer" shots. Now, if we're talking dangerous game, I turn to my 375HH. My experiences hunting include African game and all over North America. But these are my thoughts. To each, their own.
