interesting fact that the rifle is chambered for the 8x58R Sauer &Sohn one of the older so called Express cartridge because the mother case was the 360 BPE 2,25". such express cartridges had a lower pressure than 8x57 rimmed and rimless and were used for early weaker break action guns. the old Werder rifle get a new breechblock when the rifle was rechamberd from 11,5x50R Werder to 11,15x60R Mauser 71 in the 1870s and seems it was strong enough then for small bore nitro rounds.
