I recently bought at auction four RCBS Rock Chucker presses.
Two of them had swaging dies and ejectors set up on them but there was no information or marks on them to tell me what they were for.
Any idea what make these are? They look to be of good quality. The form die looks like Detsch which would be good.
The core die may be for making cores for .223s using 22rf brass. They slip right into a 22rf case.
I was hoping that the forming die would be .223 but it turns out it is .243" and makes a nice spire point. I know because I tried to run some 22rf jackets in and they come out wrinkly from being undersized. Then measured with pin guages at .243"
