, only in the slightly more common 8x56r, ammo is made in small lots for these.. it's made in the same factory, the same year, ŒWG in Steyr Austria in 1917, but it took a different path in life. The Wn-17 acceptance stamp has been overstamped with the "S" rechamber stamp. Other than being rechambered from 8x50r to the longer, more powerful round, the rear sight was updated from Schritt to meters, it has a long rifle sight graduated to 2200m. Also it has the front sight band, which usually indicates a cut down long rifle. The bore while somewhat dark, has very strong rifling in it, many I've looked at in the past....left a whole lot to be desired. But... these rifles are 100+ years old and never saw any non-corrosive ammo.
Along with the rifle, I managed to locate a nice stash of German M-30 surplus ammo, with various makers, years and enbloc clips. And, I had to try it.. it's no K31 in smoothness, and it will punish your shoulder with recoil. It fed great and no sticky cycling after being cleaned and lubed before hand. It's right up my alley, I thought my Mosin M-38 with yellow tip heavy ball was a thumper, nope, the light rifle weight, it measured just a hair over 7 pounds.. like 7 lbs 3 oz.. and the 210grain bullet it fires takes the recoil and your shoulder to a sightly higher level, think of it as being sucker punched, then you just get aggressive with it and don't baby it, it cycles and runs fine.
RM disclaimer... if'en you cant handle the Mosin.. just don't on one of these.. must be this tall to ride this ride..
The front band is matching to the rifle.. the bolt has no serial.
The stock, has been on, this is the third rifle, so it was most likely installed and force matched during the long to short rifle conversion and rechambering process.
It's kinda dark, with no pitting.. the rifling looks really good given the age and corrosive only ammo usage. Proof.... corrosive ammo won't rot your barrel off if you do your due diligence and clean it correctly.
Ammo stash.. some from 1931 all the way to 1940, both Bulgarian, Austrian by various makers and Nazi stamped enblocks. I will be picking up some modern made ammo to save the surplus stuff.
