I have a Cooper with a enlarged chamber that is now back at Cooper for a re-barrel. The cases have been sized in a Redding body die, but are still too large in the pressure ring area. I need to run them through a small base die. I intend to hone the neck size area out to have it as Small base body die. Do not need the seating die.
Anyone have just a small base 204 Ruger die they would be willing to sell?
