Hi

Can someone tell me what is the caliber of the round on the right in the picture? It's longer than .22LR but shorter than .22WMR.

Overall length 27,5mm ~ 1 5/64 inch
Case length 18,2mm ~ 23/32 inch

.22LR on the left side

That looks like one of those 60grain sub-sonic Agulia rounds.
22LR that runs a little less than 800fps. I had some but it key holed from all my 22s.

Yes it does.

I believe tha's a 22 WRF( Winchester Rim Fire). They're longer than a Long and shorter than a mag. Common in the old Winchester pumps.

Bingo.....

Not an Aguila SSS. The case on those is actually shorter than standard .22LR in order to have the 60gr bullet fit the envelope.

+1 for .22WRF. Precursor to the .22WMR.

No, it is not a .22 WRF.The WRF is larger in diameter than Long Rifle and uses an inside lubricated bullet. The cartridge shown appears to be dimensionally identical to the Long Rifle except for case length.

It is most likely a .22 Extra-Long Rimfire, a black powder cartridge that has been out of production since the 1920s or 1930s. I would be surprised if more than a few forum members have ever seen one or would know what it was if they saw it.

.22 Extra Long - Wikipedia

Here is a link to a Wikipedia article about the cartridge, along with a photo of a .22 Extra Long cartridge beside a .22 Long Rifle. The photo is virtually identical to OPs photo! Saves me from re-creating the photo with cartridges from my collection.

Thank you, I agree. Having studied the matter more closely, I have come to the same conclusion. I have two such cartridges, but I have no idea where they came from. In any case, I'm not going to shoot them.

Here's another picture, looks like a Fiocchi.

Can I go back and edit my opinion?

Learned something new about guns today...

I'm not so sure the question isn't about the round on the right as much as it is about the round on the left. The round on the right looks like a regular 22 long rifle. I think the round on the right is modern as it has a nickle case. The round on the left however looks like one of the new "tactical" rounds with a heavier than standard bullet designed for use in a suppressed gun. Some of the ones out there now have a shorter case to accommodate the heavy bullet.

...or, after looking at the picture a little more, could it be that the round on the right is a type of hyper velocity Stinger type round? I'm not familiar with weather Fiocchi makes that type round.

FYI

For reference, the Aquila SSS round is shown below... I believe it actually uses the .22 Short case

The .22 LR case is approximately 0.610" long. If the case on the right is 18.2mm (0.717") it cannot be a .22 LR. But the 0.717" case is too short to be a .22 Extra Long (0.75") or the CCI Stinger (0.74"). And it does not look like a .22 Stinger bullet (which is the shorter .22 Short bullet). So I have no idea what it is.
