griss, Very Nice Piece! Yes that one is a 9X57 from JP Sauer. Made in 1906. We've always used the .358 Hornady RN with 3031. Hope that helps ya out. You have a very nice rifle there!
BTW the ammo in that pic is a box of original Wichester Western 280gr RN. Some day I'll chrono one of those...I was always curious.
