went to a local sporting goods store for 7.62x54 ammo for my hungarian mosin nagant. they advertised it as being on sale. well anyway i picked up forty rounds. got them home and low and behold something did not look right, especially since i compared these rounds to 7.9x54. they newly purchased ammo came in a plain brown wrapper. i asked they clerk who made this ammo. he said it came in a plain green can. i asked if i could see the can and he said there was nothing on it, no writing or anything. these rounds appear to be lacquer coated. at the base two numbers are stamped 89, below the number 6. there are no other stampings on this ammo. my best guess is that this is a 9 milimeter round. it definately is to large as far as the diameter goes to fit in my mosin. anyone have any ideas.
