firing pin mark on case

[r-palm16]

Hi guys, while busy on the range today I found a .22 doppie with a strange (to me at least) strike mark on the rim.all the 22s I know make a mark on 1 side of rim but this one basically halved the case head.it goes straight through side to side.i am now very curious to know what firearm makes that strike mark.hope one of you can enlighten me a bit,thank you.

There was a thread in the last week detailing this exact striking pattern. Unfottunately the name completely escapes me. Have a look in the "Post your rim fire pics here" thread.

Gevarm semi-auto. No firing pin,just a ridge on the bolt face.Fires from open bolt. No extractor either.
