In the last couple of weeks, some members have shown automated decapping machines they built. They were truly impressive devices and I mean no criticism in the questions that follow, only to suggest an avenue for additional exploration.
What I noted with the decapping process used replicated what reloaders normally do on a press; to shove a pin through the flash hole to mechanically knock out the primer. My concern is 1) what about those oddball cases with smaller than normal flash holes that might bend or break a normal decapping pin, and 2) what about Berdan cases?
In order to not have the automated process fail because of either oddball flash holes or Berdan cases, it seems that someone using an automated machine would need to inspect their brass before using the machine to avoid stoppages. And then I wondered whether those concerns might be able to be addressed by forcing the primer out of the case using compressed air rather than a pin.
Thanks for any information you can provide.

- Has this been tried before?
- If so, was it successful?
- What are its limitations?
