Was thinking that there are guys on this site that have built their own loading press. The question I have is does anyone on here have any information on what the tool looks like that the shellholder seat is milled with or where to buy one?
It's called a woodruff key cutter. You can probably get by with a 12" diameter by 1/8". 9/16 diameter would be perfect and make it easier if you are using a manual mill, but it seems to be a non-standard size.
