I am in violent agreement that a rimmed cartridge should not work in a Schoenauer magazine. It is NOT a straight walled case, it looks just like my other 9.5 bottle necks, it just has a rim.

I bet 16 euro that the "R" in the description was a mistake. I lost that bet.

The box is marked "9.5X57R MS". The case, as above, is marked "9.5X57 M.Sch."

So this shouldn't exist, but there it is in my kit.

I agree, it would make an interesting kiplauf or double rifle, or may even work well in a drilling or vierling. I just don't know if I'd ever come across such a beast. The Holt's one looks interesting, and I may have paid 400 pounds... but brass will always be a problem for any of the above, so I'm not "that" interested.

I am curious if anyone else knows anything about this. It's a mystery to me. 16 euro does not disturb me, now I'm just curious.
