Derimming 22 Mag Brass for 6mm Jackets

[deltaenterprizes]

I have a set of 6 mm swaging dies a finally have time to attempt to make some high quality bullets.
The derimming die removes the rim but is leaving a ring around the base.
What size should the ring in the die be and what diameter should the punch be?

I stumbled on to the answer !
I talked to Dr Blackmon and his and wet was that the punch was too small and before I got a chance to make another punch I saw a couple extra ones and measured them. They were all smaller so I tried the smallest which measured.217” and it worked fine!
The larger punches were not going deep enough into the case .
They look beautiful!
