I guess anything could be a sniper round. If I were a sniper, I'd probably prefer rounds of scotch.
I've never heard about this cartridge. It sounds like a .270 necked down to .22. Other than just wanting something odd, not really sure the purpose. Even with the best .224 dia bullets, you're going to be hard pressed to get a bc much over 0.5 and I would assume barrel life would be very short. What does he do with this rifle?

There is a .22-250 cartridge.
Might that be what you are referring to?
It would basically be a .22-06 which was a wildcat cartridge that never found a place in practical cartridgedom.

Thanks .. No, I shoot 22-250 a lot and load a few of them.. Will check with him again. I think it is a 270 down to 22 dont know what it started as . I think some snipers like stuff like this.. now he is shooting at 600 yds. working on 1000 yds. Will get back to this after I visit with him again...
It is just a Wildcat Cartridge built on the .30-06 Springfield, but then so is the .270 & a dozen other cartridges..............

22-270?
Since the .270 is already just a necked down 30-06 then shouldn't a .22 version be called a .22-06?
There is already a .25-06.
Sniper round? *** is it with all of this Sniper stuff? Is is not cool to have a hunting rifle anymore?

Like stated earlier this round would be a barrel eating machine. Anything over 4,000 fps eats the throats out of barrels quickly and this number would be well over 4,000fps eaven with heavier .22 cal bullets.

Wildcatters have been messing with hotshot .22s and 6mms for decades. Not long after WW II, a couple of guys created a .22-.50 Ma Deuce cal. Short-lived project. 
The .22-250 was once Jery Gebby's "Varminter", back in the 1930s. He was a Nebraska gunsmith and prairie-dogger.
But real, official military snipers? I seriously doubt any of them ever had occasion to use any sort of hotshot .22.

Your "friend" sounds like he may be blowing hot air...
I know it is splitting hairs, but the 270 is actually a 30-03 necked down to 27 caliber. The differences between 30-06 and 30-03 are very minor, less than 2mm overall lengh. Never heard of either 22-270 or 22-06, but not really surprised they exist.
Actually, the 270 Winchester is the 30-06 necked down to 27 caliber. The neck of the case grows longer when necked. They may not have trimmed the case length after re-sizing.
For more information about the 22-06, look up P.O.Ackley's twin volume book set (I forget what the title is but it will be easy to look up.)
Another good long range 22 based cartridge is the 22 Cheetah which is the 308 Win necked down to 22. A tight rifle twist is used to stabilize long VLD bullets. Ross Seyfreid found it to be very accurate out to 1,000 yards

Here's a article that deals with the 22x64 (22-270), I would be concerned about barrel life, and a stainless will give you some 20% more life.

No .22 centerfire has anything to do with snipers.
But especially that one.
A sniper would burn the barrel out of a .22-270 in less then a weeks practice.
So will your friend if he can shoot well enough to know it.

Packing 57gr of powder behind a .224" bore is about like cramming a turbocharged 454 big block into a go-cart, sure it can be done, but why? The chassies cannot handle the power and neither can the .224" bore. 22-250 is about the most overbore cartrage I could imagine making a case for, and even that is pushing it. .22cals make piss poor "sniper" rifles, those bullets lack the ballistics for true long ranged shooting no matter how fast you push them. 6mm is the smallest caliber I would even consider for long ranged work, and it is easly trumped by the slightly larger 6.5mm and 7mm for that task.

As peviously mentioned, barrel life would be measured in the low hundreds of rounds, making it quite impractical.
As far as a sniper round, just saying something like that makes the OP sound like an internet warrior. Except for shorter range police situations that are already covered by .223, 22's have relatively poor bc's and limited downrange energy for true sniping.

I dont see him as a mall ninga and he is no blow hard and was a sniper, has money and can replace barrels often. I didnt say he used it as a sniper, I think he said a 308. He just shoots for fun and this is fun to him. I dont know what his inspiration was, but I do intend to visit him about it again . I would like to long range shoot but only have about 120 yds clear open space so all of my stuff works good here. thanks for the comments people...
What bullet is he shooting?
If you're interested in longer range shooting systems, get a Ruger 10-22 and a 4x scope with a plex reticle and finger adjustable turret (often resttable to "zero") on the cheap and learn to apply reticle subtension vs. trajectory to ~150yds. and 200 yds.+ with the turret. You'll learn a lot and it won't cost much.

Hey don`t knock it till you try it, I have a buddy who has a Vega with a blown 454 in it & that is about as close to go cart as you can get................
O K I will come back with cake on my face... I visited with him again and he now said 22-250 but I heard 22-270 3 times so. I thank all that had a reply both good and ??? I guess I will have to work more on shooting my 22-250 again... I did learn some things from this post. may have to get one of those scope levels ...

For a while there were guys chambering the 22-250 with long throats for VLD's. Can't see it myself.
Now, if you want a way cool round based on the 30-06 that's good for 1k, maybe think about a 6.5-06
