Up in NewChina, we can't own handguns anymore... so I can no longer dream of reacquiring my Dan Wesson pistol pack.
I used to think like you. 22LR, but have since moved to the thought of downloaded centerfires. If I had to have only one, it'd be a 223. although my least favourite, Brass would always be available. a 222 would be near the top right beside my Hornet... hard to decide.
as for shotguns, while I really like my .410s, I'd go with a 12ga, like my Mossy multi barrel setup. I have barrels from 14" to 30" and several in between, with some rifling in them as well.
for rifles, I get your love for the -06. truly I do. But not being American, there is no real love for it.... and there are others that can do what it does, and more.
I think we'll have to agree to disagree on "The King"! Hahahaaaa...
