Do Lyman and RCBS top punches with the same number have the same configuration? Specifically, does a Lyman 421 have the same configuration as an RCBS 421? Thanks.

Doubtful, that would just be too easy :-D...Ray

Actually they are interchangeable in almost all cases.
For instance I have a Lyman #421 and a RCBS #421 top punch.
They are identical.

Not always! Use the RCBS aand Lyman mould charts along with the appropriate top punch charts and you can get a good idea of what will work! I use more Lyman moulds than RCBS; however, some of my RCBS top punches will work on some of the Lyman moulds - BUT IT IS NOT ALWAYS THE CASE!

castpics.net has a cross-reference table

Some match, and IIRC 421 (Kieth .44 mag nose and clones) is one that they agreed on.

Many have zero relationship.
