Too many barrel wall thickness gauges out there and people know how to use them. So if you just bought a gun that is out of proof and it was discovered by your gunsmith while he was checking the gun out what would you do contact the seller or contact the exporter unless they are one in the same?
To help in my understanding of "in proof based upon proof law", which countries have minimum wall bbl thickness stated in their proof laws & what is the minimum thickness?
I know .020" is suggested by some as minimum wall thickness but I was not aware that being below .020" bbl wall thickness made a gun out of proof assuming it was otherwise in proof.
I'm not arguing that the .020" minimum doesn't make sense & that a gun w/less that .020" may not pass reproof but please clarify on the Proof Laws.
