Rimless Grooveless Internal Primed Centerfire

Here is an interesting piece that I’m not sure what to think of! Supposedly it’s a .22 caliber internally primed centerfire rimless and grooveless cartridge. It has roughly a 24 mm case length. Attached is a picture:

I know of a handful of patent-fire examples with similar construction, however I’m blanking on a .22 caliber. Anyone ever seen anything like this?

My first thought is a .22 case draw piece fitted with a bullet. I assume it is not headstamped.

Completely blank on the case head with a slight bevel.

Fede, you are correct. It’s a draw piece with a bullet stuffed in the case mouth. No case mouth crimp is visible. I have collected .22’s for nearly 50 years and see one of these every two or three years. It would have been nice if it was an experimental, but sadly not.

Cheers,
Will.

Thank you for your answers! I had a feeling it was a draw case, but was hoping it wasn’t.
