^The ammo came with the gun. My father got it from an old uncle of his.
With The gun having been born in 1995. Ammo is from some time after that. Gun seems in pretty good shape. Looks like it was taken into the woods a good bit, minor cosmetic stuff. But I doubt the old guy it came from was exactly running through boxes of ammo.
Box is mostly empty. He probably bought the ammo when he got it. Sighted in the rifle, took it hunting a few times and decided it was too much gun for this state and his age. I do not know if he purchased it used or not. Wish there were some way to figure out when it was from.
