.22 XL RF Cattle Killer?

Hi
I need some information on this rimfire cartridge of Cartoucherie Fran

I beleive this is a .22 Extra Long Tool Blank for a stud driver tool.

It’s probable.
But what stud driver tool?

That I can not help you with as I have no French stud driver catalogs. A trip to the nearest construction equipment dealer in your are might provide an answer.

After information, It is
