Hi there,
here's a pretty impressive video of 860yds shooting with a .223 rifle:

If you were to build your ultimate .223 long range rifle,
1.) what barrel would you use (and why)?
2.) what barrel length would you use (and why)?
3.) which rifle platform would you use (and why)?
4.) which factory ammo would you use if you had to (and why)?
Please do not suggest other calibers etc (I know that).
This is a .223 only thread.
If you want long range accuracy out of a 223 here is a fool proof recipe for success.
Mark Chanlynn SS barrel in 1-7.5ROT (cause its the best)
30" long (you'll see why in a minute)
Any quality bolt action, preferrebly in a single shot because it provides for maximum bedding surface contact
COR BON or Black Hills. (I know the people and they build good stuff)
I've built a handful of long winded 223 bolt guns for guys. You basically have to start backwards with these guns. The bullet determines everything and for this kind of shooting you have two choices. Either the 80 grain Berger VLD or the 90 grain JLK.
80 grainers work in a 1-8 and the 90's require a 1-7 to 1-7.5
You load em smokin hot to where the primers are ready to fall out and then you go for it. a long barrel gets the velocity you need while keeping some resemblance of sanity with regards to chamber pressures.
The last two I did were on barrels that finished at 30" and they both shot exceptionally. The guy's last name is Savage and he lives out in CA.
A Phoenix Machine, Nesika, or BAT action are all excellent choices for this kind of gun.
If you have anymore questions just PM me and I'll be happy to help anyway I can.

Footnote:
The year was 2002 and it was a 1000 yard Palma and "any/any" (meaning any sight/any rifle) match out by Grand Junction, CO. Chris Hatcher, a shooter from the US Army National Guard Team showed up with his AR-15 National Match Service Rifle set up to shoot 90 grain JLK bullets.
He won the match. Beat guys with purpose built Palma guns and the any/any crowd.
It can be done if you can hold elevation and be jonny on the spot when conditions change.
I've personally shot a 3" spotter five times in a row from 600 during the Colorado State Championships (2002) with my service rifle (80 grain Berger VLD's).
