All the battlepacks I have left are unopened.
I'm looking at one and at the bottom of the label it has
818 A 88Z another has 376 A 86. I would guess 1988 and 1986
The oldest I had seen was 1985 and the newest 1988 of the ammo
I have shot and I have shot a bunch of this stuff in the past. We could open some up and inspect them when we meet. I kinda hate to open them now, but I guess I could if it becomes an issue.
