Thanks for the informative post! Although I have no intention of casting bullets at present, I may in the future and would likely have ended up crumpled in a heap beside the garbage can....
On another note, when I bought the place I live in now I wasn't into guns much, other than 1 rifle/1 shotgun/1 22lr. Anyway, there was an old shed in the back yard and the previous owner had left a bunch of stuff in it. In one corner there was a huge pile of wooden trays filled with little metal rectangles with letters and numbers on them. There must have been 300-400 pounds of the stuff. I couldn't imagine what someone would horde that crap for.
So I took it to the landfill.
