Let me run out to the reloading room and see if it's like some just after WW11 stuff I've got, it's curpro nickel too but I don't remember if it's stamped or not, I'll check for ya, see if it is the same. Doe's the box have any stencleing on it? That will help track it down, or is it just stencled 8x57,, Even if it's stamped 8x 92 or 8mm Mauser or a date code on the box, it may not look like one but there usually there somewhere sense not on the base ,,that could help too. What ever writing thats there can help, maybe not by me , but by those that are specification junkies,, they'll know if I can't help. Be right back Bluejack
PS,,,, Nope mine is headstamped, didn't bother to look with what, but the wooden box just has 7x92 , quanity and weight on it, sorry no help here. Didn't know if it might have been unstamped too as the box is unstamped and its in strippers and bandoliers and haven't used it in a bit,,, zombie ammo ya know. If there comming at me I won't worry bout shooting that real carrosive stuff through my nice Mausers then!!! But not now, all my mausers are beatueys and never shoot carrosive through all but 1 or 2 of them. Sorry couldn't help out bluejack. The kernnel will know I'll bet, he's amasing sometimes!!
