Not gonna happen. With a 26in barrel and rl-26 you could probably do it. A creed with a 22 in will get you 2750-2800 with a 140 depending on powder and brass.

Here is a fairly comprehensive analysis for you-
http://demigodllc.com/articles/6.5-shootout-260-6.5x47-6.5-creedmoor/?p=1
I have a .260 & at the time of buying there was no Creed, in hind sight at the time I should have gone 6.5x55se, mainly because there was next to no factory ammo available for the 260 & what was available was super expensive.
Hence my 260 has never had a single factory round through it!
The alternative is to AI the 260
6.5x55 will give you approx. 100fps more but of course its in a long action(except for tikka)
I guess if you want more energy down range then you could look at 6.5x284

I have 1 Savage 110 Tactical 6.5 Creed, 1 Savage 111 .260 Rem hunting rifle, 1 Savage 10 .260 AI Target, and I am building another .260 AI on a Savage 110 FCP with a heavier barrel than my first one. 6.5 is O.K., .260 is good, and the .260 AI is even better in my opinion.

I can get 2875-2890 pretty easy with 28" h4831sc and 142 smk's out of my .260. With h4350 and a 6.5 creed I never got above 2800 with any accuracy out of a 23" barrel and 140 elf-ms. My accuracy load was 2700-2710. Now at around 20", it actually shoots a little faster at 2725-2735. Rl26 I could get a little more than 2800 but it was a little finicky and I ended up going to h4350.
If you are building it I would go .260 and plan to load 2.900" coal. You can pick up a little more speed on the creed if you load long, Wyatt's and a bdl it increases my set hunting distance 100 yards. Factory I just don't know you can buy a .260 that is set up to take advantage of a longer case.
As an aside, my .260 is a better shooter than my 6.5 creed, but they are different rifles built for different means and both are consistently .5 moa or better.

And why is that? "Anything" is a pretty big category.

I used this bit of wisdom and even though I reload, I still went 6.5 Incredimoor X3...make up your own mind 
So let's get back on track here.
We are discussing the 6.5 creedmoor and the 260 as my choices. I have read where people are getting 3050 with a 140 out of the 6.5 creedmoor and 3100 out of the 260.
I wanna do that with a 22" barrel. Is the 260 the way to go? Will the 6.5 creedmoor be more accurate?
It seems as if a lot of people want to express their opinions on something I didn't ask about.

I don't think those velocities are possible with either of those calibers. In fact, I can only get 3050 Fps on the average with my 6.5 SAUM and 140s.
I have both, 6.5CM and 260 Rem and both are Tikka's. The 6.5CM has a 24" barrel and I can get around 2800 with 140's. The 260 has a 22" barrel and I run it as a long action. I can seat 140 grain Bergers at 3.00. With RL26 I am getting 2910. The fastest I pushed it was 2930, but had some pretty bright extractor marks. I don't see how you will get in the range of 3K with a 22" barrel.
Those are some lofty numbers for either of those rounds. Just because you can cram enough powder in the case to make those speeds and the bolt still opens after you fire it, doesnt mean its smart to do. 3000fps from a 140 is gonna be way over 62k cup pressure.
The standard chamber in the creed is built for accuracy. The freebore is .0005 over .264 so the bullets dont get out of shape before they contact the rifling. The straight wall case helps to keep the bullet square with the bore if you have a loose factory chamber. The 30* shoulder gives a flatter surface to headspace off of, make that part easier for manufacturers. If you took 20 factory rifles in 260 and 6.5 creedmoor each a ran them through an accuracy test, I feel confident the creedmoor would win on average accuracy just on what we have learned about case design in the last 30 years and was part of the creedmoor design. Same case philosophy is used in the wsm cartridges, 6.5x47, 6.5 prc, 22 br ,6mm br, the noslers, etc,etc......
BUT........if you ai the 260 , you have just done the same thing to that cartridge. You can use a reamer for the 260 that has a tight, longer freebore and take 80% of the advantage away from the creed. Factory gun.....creedmoor, custom build.........whatever your mind can dream up if your wallet can take it.

With a 22" barrel and the 156 Berger I would be suprised if you could hit 2700fps with the creedmoor. Especially if you want the brass and barrel to last.
