Well then, (
) to weigh in, IMO, if a fellow was not interested in hunting the great bears nor hunting where the great bears roam, and didn't have elk on his menu (more about that later), he would hard pressed to find a cartridge that would out do the 7-08 in real world hunting.
That opinion is based on hunting with rifles from .300WM's on down. The 7-08 just gets the job done with such blue collar efficiency that it's almost embarassing to tell the wife you "need" a new rifle. If you're hunting deer, pigs, black bear, a 7-08 is all you need. If you reload and want to go elk hunting, load up a bunch of 160's and go. Just be aware of you limitations. Which you ought to do anyway.
If a man has a good rifle, he, maybe, shouldn't run out and sell it to get a 7-08 but if he's starting out, he'd be wise to start and finish with a 7-08.
From a reloading point of view, they are like a 30-06 in that they are one of the most agreeable rounds you can load for. It hard to find a load that they won't shoot well.
Low recoil, accurate, easy to load for, readidly available ammo, deadly, the 7-08 brings it all to the table.
In another thread, I told how my son had made a shot on a mulie at 280+ yards with a 18.5" barreled 7-8. Well, our longest shot ever was a 380+ yard shot on an antelope with a ta-da .280. But that's another story.
