In another
section I went over how to make cast lead bullets. There is a limit to how fast
these can go. That’s one of the reasons for jacketed bullets.
A modern
bullet is normally two parts. There is a lead core to give it the mass and a
copper jacket to hold it together before, and after, it hits. There are other
types, but the copper jacket represents the bulk of the market. While far less
common than casting lead bullets, there are people who make their own jacketed
bullets.
