I think they are playing a bit fast and loose with the term “in proof”.
To be in proof at that .006” measurement, the gun would have been proofed at .016, at maximum. I’ve measured exactly zero 2” chambered 12s, but, know enough people that have to discover that .020 wall thickness and under, is not uncommon. If it was submitted for reproof, today, it would fail the “view” phase, if pits are present.
If it was submitted for reproof today and made it past view, it would be torn apart with the revised procedure.
I highly doubt it would make it past view.
Best,
Ted
