I have got a lot of 9x57 Mauser ammo, stuff that was leftover of a schwedisch moose hunter. this unknown gentleman had have cartridges from before WW1 up into the 1960s.
the lot contains also some 9x56 Mannlicher Schönauer cartridges. I try them into my M 88 in 9x57 Mauser and they load fine and would be safe to shot.

full boxes, I suspect the Kynoch ammo was bought beetween 1945 and 1955 when german made ammo was not available. the finnisch made ammo box is a very early post war made. headstamp is VKT, a firm that become VMT in 1946 and become a Part of Valmet in 1951.

mixed bag, interesting only one Norma round was in this lot, maybe he shot it the most. the third round from the right is a hollow point. the first hollow point in 9x57 I had in my hands.the fourth from the right seems to be the old 14,9 gramm DWM load.

the old german ammo have the "491 A" headstamp (DWM case number) or is stamped with M88/9x57 - the original cartridge designation

9x56 MS and 9x57 Mauser by DWM both with 16 gramm bullet

RWS and DWM also some interwar period Geco make the mass. you could easy recognise the 16gramm and the 18 gramm bullets. both bullet weight are fifty-fifty in this lot.
few but also some 18 gramm full metal jackets! the second from the right is remarkable because the bullet is not nickel plated(RWS load).

when compare the bullet one notize that there a differences over the years but the bullet's were sold under the same number. here two RWS cartridges - same bullet weight, same number in the catalogue

the difference between the 9x57 and the 9,3x57 is the cartridge lenght with different bullets
from left to right:
9x57 16 gr bullet
9x57 18,2 gr bullet
9,3x57 18,5 gr bullet
9,3x57 18,5 gr bullet
9,3x57 16,6 gr bullet

the 9,3x57 was and is loaded to a shorter oal with the heavy bullet weight so having less space for powder than the 9mm Mauser

by the same dealer I have got 11,2x60 Schüler rounds, DWM made
this is one of the very expensive collector cartridges and I have steal them(it was legal).

original and handload(Horneber brass and Degol bullet)

would be very interesting to shot them through a chrony but I dont think doing it
