I have these 2 shell holders, both came with a set of 32 acp dies. One is marked 7 and it appears to be close to correct, a little slop but works and the other is numbered 17 and looks much older. My charts show 17 as 303 Brit and such, but this is definitely not 303 Brit size. It is a little to sloppy on a 32 acp as one will damage the rim if the primer goes in with much force at all.
Any idea what my #17 really is designed to fit?
