Title says it all. I recently acquired a used 9mm Square Deal B. I would really like a powder funnel that has the same dimensions as a Lyman M die. From what I've gathered on forum searches, the Mr Bulletfeeder funnel may not expand quite as much as a Lyman M die. Do we have a resident machinist on the forums making custom powder funnels? I see one guy on eBay used to make them, but he only has a .40 cal listed and doesn't respond to messages. I'm looking for something like this but in 9mm:
