natman, sorry, but you could not possibly be more wrong.
So instead of spending most of your post restating the OP's criteria to fit your preferred conclusion (30-30), you've now decided to ignore them completely.
Yeah, just like you did when you recommended .30-06.
I suspect that a 300RUMAI would not meet the OPs criteria of affordable, available ammo and rifles, not to mention recoil.
Wow, gee, ya think? Kinda like one OTHER recommendation from SOME people.
I realize you are exaggerating for effect
Ummm, yeah.
but while the 30-30 was at one time considered a powerful, flat shooting marvel, that era lasted only 12 years - until the introduction of the 30-06.
And yet every year up to and including 2009 - over 100 years later, truckloads upon truckloads of leverguns in .30-30 are sold and used to good effect.
The 30-30 is adequate for 90% of hunting as long as you stick to deer under 150 yards.
You're making me laugh hard man. Under 150 yes, I agree with that. Guess what. The vast majority of hunting is done under 100 yards, let alone 150. But all give you that. As for deer sized game, wrong! You're just way off base there. Ask caribou, who just explained today that natives who hunt HUGE game in Alaska consider the .243 to be an excellent choice. The .30-30 will kill anything on the continent, any day, all day long. Easily. With power to spare. At appropriate ranges. Does anyone on this board have more hunting experience than caribou? I think not.
But the OP wants a gun for 90% of ALL hunting,
No he doesn't; you are wrong; he said:
Appropriate for 90% of the game in North America
It is you who is not reading the criteria carefully. He didn't say ALL hunting, to imply long range hunting, as you are trying to impute to him. He said 90% of the game in North America. As it turns out, the .30-30 is appropriate for around 95% of the game in North America, counting species, and 99.99% of game in North American, counting actual heads of game running around.
which includes larger game and longer ranges.
Again, he didn't say longer ranges, and it's fine for moose or any large game you can think of, except perhaps grizzly or polar bears.
Given the OP's criteria as HE wrote them, the 30-06 is a far better choice.
No, it's not. It's a good choice, which is why it was #3 on my list. But it's a LOT more recoil, and a fair amount more expense, both of which fly in the face of his most important two criteria.
