from my understanding the .308win is perhaps the most accurate centerfire cartridge out there. this is assuming all other variables are equal. but if someone, say me, wants a little more umph, what would be the second most accurate with a little more firepower. i know this is open to a lot of subjectivity, but lets here what you have to say.
very correct, this is a subject of controversy. Wanting the accuracy of the 308 with more power is a tough one. I have one suggestion if your up for a challenge. Try a .308 Norma Magnum. This rifle has ALOT of umph...more than the 308 win ever thought about. Accuracy comes along with it as well. This will be a project unless you buy one already done and if done right it will be a highly accurate hunting rifle with lots of velocity and kinetic energy.
I have one of these so if you want more info on the caliber let me know

Snipers, we can probably agree, know a little about accuracy.
Their favorites seem to be the .308 Win; 300WSM, and the .338 Lapua...the .338 is more than you need for anything in North America(and it aint cheap to shoot)

Basicly what it comes down to after the action is trued, trigger job done, and if bedded right, is how good is your barrel? How much are you willing to pay for accuracy? Layne Simpson has a 300 Kong that will do .25 at 100, but it has a premieum barrel on it. A good barrel blank costs as much as a good production rifle, and it must be done exact. The smiths who do this work and guarrantee bug hole groups are not cheap.

I tend to support the .30 caliber as being intrinsically accurate. The military has used it for many years, both by snipers in combat and for competition. I have two 308 Win's that will shoot a 5 shot single ragged hole at 100, and will consistently shoot under 2 inches at 200. I also have a 300 Win mag that will do the same if not better. I also have a 223 that will do the same thing.
However, the subject of accuracy must take in many details: action, barrel, stock, sighting system, proper assembly, and load development. But the most important part of the equation is the skill of the operator.
This is always a fun topic. Let's keep it going.

It really depends on what you want to use it for? Any chambering can be accurate if it is loaded right to compliment the rifle it is shot out of. Are you talking knock down power, long range stuff, a flat trajectory, what exactly? It also has a lot to do with bullet type and weight.
Technically for long distance stuff a heavier longer bullet works better because it has a better Ballistics Coeficient, and the weight helps in the wind. This why many Military long distance match shooters and snypers like the .308 so much, and tend to go with heavier bullet weights at longer distances (1000 meters). Sure it's not as flat, but it has a better BC and carries more energy to the target.
As far as flat shooting and accurate most of the varmint type cartridges work really well, like the .223, .220 swift and 22-250 and the likes.
For utmost accuracy it really boils down to the guy loading the rounds and how much home work he puts into it.
I used to have a browning HI Power I bought used from a coworker in the military. He gave me a bunch of handloads he had left for it when I bought it. It shot pretty good with the right factory ammo, but was amazingly accurate with the handloads he worked up for it.

I have great luck with any short action. 300WSM, 270WSM, 308, 243. Velocity spreads are very low, and very dynamic load. I have yet to load for the 6.5/284, but from what I seen from my friends, they have extreme good luck. Don't expect 16fps spread with a 300RUM, or 300win mag or many of the long action calibers no matter what is printed here. Sure, I have gotten them to shoot just as good. But its so easy with the short actions, in my opinion. I get velocity spread upwards of 50 to 70fps with my 300RUM. This is with a custom gun and two others. I get them to shoot .5" groups at 100yards but you can see this velocity spread over 500yards. I start getting verticle spreading.
