I don't see how proof laws protect any buyer against buying an unsafe used gun. The laws do not prevent anyone from honing a bore past the proof limits, it just prevents it being legally resold that way. So, we are to believe that everybody became honest because of the laws? Baloney.

A buyer still must be educated enough to either be able to measure and determine if the bores have been honed too much, or hire a capable person to do so. Caveat emptor is not nullified just because laws exist.

Until everyone abides by laws, you're still on your own to protect yourself.
