I have the 21st Century mandrels, 6.5mm/.223 and die body. Pretty straightforward to use and adjust for each cartridge.

The 21st Century and Sinclair mandrels are propietary and will not interchange. I have used the Sinclair system for years and have had no problems with it.
If I agreed with you, then we'd both be wrong.

They are 100% interchangeable. I have both mandrels, die bodies, and 21st Century turning lathe. All mandrels are interchangeable (except the extended length mandrels from 21st Century).

Then I stand corrected as the Sinclair that I have is a completely different design.

You possibly have the 1st gen Sinclair if it uses a set screw and isn't captured within the die on a shoulder.
