Little bit of extra info...

I served mandatory military service in the Bundeswehr back in the day.

Every single bullet was accounted for: All bullets were numbered, and when we would go to the shooting range we'd get bullets from a batch. We made sure that all bullets handed out were actually used, and all of our names were recorded with that batch of bullets - if any bullet of that batch ever turned up anywhere else, they would know who to check.

With that in mind 60k bullets is large number of bullets to be lost.

Edit: Grammar and spelling. Edit: Back then these were 7.62mm rounds for the G3, and (I think) 5mm rounds for the uzi (or uzi-like).
