Here's a shot of some of what I pulled out. Head stamp appears to be '47,' so this ammo was probably packed for long term storage shortly after being produced 65 years ago.
Something like a nice musty pine scent accompanied the opening of the can.
I've previously shot Soviet bloc ammo in this caliber from the early post World War II era. Can't recall ever having a round fail to fire. Planning to give this latest batch a test in a week or two.
