I wouldn't have thought so. I have tried shooting a .22 bullet head through a standard 12 foot pound air weapon. It jammed and took two shots to clear it. The bullets are so much heavier as well than a .22 14 grain pellet. I think a .22 bullet is available between 30-60 grain.
Now you guys in the US don't have all the power restrictions we have. You could use it on a weapon knocking out 25-30+ ft lbs no problem.

However what would be the point? Get a rimfire .22 and shoot sub-sonics. All the power, non of the hassle. I think a standard .22 rifle barrel is a little slack for a pellet. I've noticed that the rifleing is shallower on an air rifle.

I'm sure somebody on here will come up with technical data, measurements and an actual size for you. Sorry I'm not technical. But what I can say is that all .22's are not equal.

Hope this helps.

.22 bullets are around .223" in diameter and .22 cal pellets range from .220-.222" in diameter. This is my experience using a caliper for various brands.

I have shot Eunjin 30 grain pellets out of an old .22 beater with blanks! Open the bolt, load a pellet and then the blank... One mean 'pellet' gun!

Tried firing .22 rounds (just the lead!) out of an air rifle but they appear to be too big to even load.

Resistance in the bore is equal to minimal needed pressure to dislodge the projectile...

I used to use Marlin Micro Groove stainless steel barrels, they work very well.

But because of the initial cost and the hours of machine time, I discontinued that practice.

.223 is for, well, .223 Remington, .22 Hornet (might be .224), and .22 Magnum. The .22 LR is actually smaller.

.22 LR barrels (even if the right size for your pellets) are designed for much higher engraving pressures than PCPs can hope to deliver. By ten times or more. Even Marlin 'microgrove' rifling is going to be more radical than we'd want I think.

Power loss and blowby are the likely results....neither of which are usually goals.

Unless you're building a real bruser where the pellets are stripping (I don't think really possible with HPA) I suspect you're far better off with the traditional offerings from folks like LW and HW. For sure if the .22 LR barrel was "perfect" in configuration those makers would use that instead of what they do. I think it's far to assume they considered it.

for many of the reasons stated, but they can give decent accuracy for a good price. Crosman barrels are often cheaper for better results, but not always.RF barrels are often cheaper than premium AG (LW orHW) barrels, but will rarely give as good a result.Depends on what you want...

I have a .22 rimfire barrel laying here, I was wondering how it would do on an airgun. Now I know, thanks!

Does it work the other way around? If you ream a .22 air rifle barrel to accept .22lr cartridge can you use it for shooting them?
