Would like to know if here's any other fellow shooters who use .222/.223/.224 caliber barrels? If yes, what barrel/twist rate/bullet combination works best for you? We have few .223 builds here in Finland and it seems to be quite decent caliber for long range precision shooting. For example NOE 51gr spitzer bullet has bc around .2 when shooting it around 280m/s (920fps). And they're accurate too! Few examples from my personal Airforce Escape build:

I play around with 3 different airguns in 223-224 and all of them have a 1:16 twist rate 

The Huben shoots a 35 grain at 980 fps .

The green Daystate Air Ranger shoots the old Eley 40 grain hp at 935 .

the Daystate Wolverine conversation likes the new mold from MP Molds 

in 5.55mm at 35 grain and shoots at 1040fps and seams to be very happy

The barrel on the Wolverine is a Green Mountain stainless and fluted 224 

with 218 lands I size my rounds at .2242 or 5.695mm . here is a pic of the .223s

Thanks for the replies.

Huben and Daystate barrels are closer to .22lr barrels than centerfire .222/.223/.224 barrels (Yeah I know the barrel dimensions are pretty close in those). There's a lot of research done and the consensus is that you'll need a very fast twist rate if shooting heavier (longer) bullets. 1:12" is good for around 50gr (or maybe few grains over, depending on the bullet shape and design).

I think it's not that odd caliber for PCP's. Sure there's no factory build guns as far as I know, other than the dutch made beaumont in .223 which uses 1:14 twist (I think it's similar to .22hornet PB barrel). They shoot RWS 41.5gr .22lr bullets out of it around 1000fps.
