I read a story one time that recounted the Viet Cong loading 9x19 cases with .32 acp cases filled with lead. I was never able to verify the story, but it's feasible.
I've got swaging dies for .357", .400", .410", .429" and .452" diameter bullets. I've figured out how to use annealed brass cases as jackets for all of those, but again, it's very labor intensive. It gives me something to do when the winter rains start up here in the Northwest.
Hope this helps.
