Here's an oddball old cartridge
At work got a bunch of old ammo someone needed to get rid of, and there were a bunch of old .22sAnd the bullets were magnetic. Coworker decided to take one apart and grabbed the bullet to twist out, but with just a little torque it snapped off at the case mouthlike this one. This is a lousy picture of the bullet itself, it appears to be compressed powder in a very thin jacket. Which reminded me of something, so today, being unable to do much still, got things together, broke this one, put the bullet on top of a can and put a propane torch on it. Got up to a bright red, nothing melted, which I think means the memory was correct: powdered iron used for gallery loads that would break into powder on hitting the backstop.

Frangible bullets for target shooting indoors?

I worked in a steel manufacturing shop for over 35 years. It is interesting to note that not only iron is magnetic, but also pure nickel and pure cobalt.
We used both of them in manufacturing alloys. Cobalt was the base metal that we made for artificial hip sockets, knee replacement joints, and in some cases pins and screws for plates to repair severely damaged bones, along with the plates themselves, which are shaped like a section of pipe cut lengthways to form a patch with holes for the screws.
