Where did you find them?
I picked up a Husky Mauser in 9.3x57 made in 1935 from what I’ve researched. I am wrestling with rechambering it to 9.3x62 since it’ll be a heck of a lot easier to source everything, or to just leave it, and go through the pain of finding dies and reforming 8x57 brass.
I haven’t been able to locate the dies anywhere.
For anyone needing a set I got mine here...
