the 9,5x47R is having the 11,15x60R Mauser m/71 as basic case

its one of over 100 different cases in all calibers and all lengths developt by using 11,15x60R brass. it was overtaken by the 8x15x46R Schütenpatrone step by step in the late 1880s and was probably obsolet by the turn of the century. but you could get brass and sometimes loaded ammo still between the wars. the old 8x15x46R also became obsolete for target shooting in the early 1930s by smokless 22lr ammo. this trend got a kick by the end of WW 2 when german target shooter lost the old rifles.
when it starts again after the war the 22 lr dominate target shooting and the old Feuerstutzen ( blackpowder - fire - stutzen) were only for some freaks.
