I appreciate your position, Windago, but have a bunch of 7-30 barrels and only one set of dies to feed them with.
Ebay sometimes has them reasonably priced.
Here's a set for $30+9 to ship https://www.ebay.com/itm/30437827821...QAAOSw8-NiHh~V
You prolly won't see em in time as it closes in less than 2 HR
Definitely keep em on your radar
