Country,
good info, keep it coming, I like history.
History proves there is not much to invent these days, it has, most likely, been invented years ago and invented again.
I'm happy to answer your questions.
These dies will be mounted on RCBS Rock Chucker press.
I try to make few more parts tomorrow, and post picture on how it mounts on press. It's so simple I've been kicking myself for a week for not realising it earlier.
These dies fit inside normal 7/8" dies and on top of these thread base punches.
More tomorrow with pictures, it will be lot easier for me to explain what I mean when you can see the pictures.
As usual, sorry for my bad English, hope you can make some sense from it.
