Fubsy,
Ever try stalking an antelope in open areas?
I have. Not hunting, just seeing how close we could get to the things on the open high desert in New Mexico to snap some pictures.
Unless you've got some seriously deaf, dumb, blind, and olfactory-challenged antelope, you're going to have a hard time getting into .30-30 range.
As for my longest shot on game, it was slightly over 400 yards (measured with my father's surveying equipment), a groundhog in Pennsylvania, with a Remington .223 that a friend had lent me for the season.
With my groundhog rifle, a .243 Remington, my longest was about 325.
I popped a groundhog a few years ago with a .300 Wby. Mag. at about 75 yards, using 130-gr. varmint bullets. Wasn't much left but a smear.
Farthest on deer? Estimated 80 yards paced off. Closest? About 7 yards.
Please don't get me wrong. I'm not in any way trashing the .30-30 as a hunting cartridge. But just as the .416 Wby. Mag. isn't really suitable as an all around North American rifle, the .30-30 isn't really suitable in that role, either, although either one could be pressed into service.
When you get right down to it, the "all around" rifle is really a series of compromises and accommodations. You give up performance in one area to get performance in another area.
In the end, though, you really have one rifle that fills one or two, or if you're lucky, three, of my criteria REALLY well, and makes accommodations on the others.
Were I to hunt ALL types of game in North America, I'd want at least two, and possibly three, separate calibers.
