    You got me thinking. Cheap, non-hollow point rounds of all sorts are jacketed. I buy the crappiest ammo I can find and the .22s are the only rounds with exposed lead. And some of those are copper clad.

    Copper being more expensive than lead, why is that? Smoother feeding, don’t get dented up, something like that?

      Ooh look up dum dum rounds, there was a YouTube video I watched recently, but if you like firearms it’s a fun watch.

      So iirc, lead is so soft that when we started using auto feeding the lead deformed and you would fail to load a round. Copper is used because it is softer than the steel barrel so the rifling will grab onto the bullet, but hard enough not to deform with normal use and in the barrel.

      But then you find out that they are bad at killing humans.
