Cool finds, My friend keeps all the scrap lead (which I am happy to give) to make a weight belt for diving. As far as the flattened bullet, I have found two in one hole and both had a different pattern, my guess it was whatever they used to squish the bullet. I think really it was a bored soldier or maybe he was going to make a game piece or sometimes they were given strips of led to make bullets and this person may have flattened one to make it easier to cut of a piece for a smaller bullet. Who knows really but its cool anyways because someone took the time to shape it.
