But he didn't have any copper.
Couldn't find it.
Despite his extensive search, he never discovered a copper mine.
He planned to cast bullet heads with iron.
And then cast the barrel with iron as well.
He had no idea if the friction between the two would produce sparks.
He seemed to have heard that bullets on Blue Star have steel shells.
He wished he could use copper for manufacturing, but couldn't find it.
Furthermore, he didn't have any lead.
Anyway, iron was the only metal available.
Iron is common and inexpensive.
So it was normal that he discovered an iron mine first.
Unfortunately, it was a poor iron mine.
How exactly should bullets be cast?
How to make the bullet shell relatively thin?
He didn't have precision instruments.
At first, he thought it would be easy, but now he began to think it wasn't simple.
Could he use beeswax?
Cast beeswax onto a small iron cylinder.
Then use a lathe to thin out and refine the beeswax shape, making it round and thin.
