Wait a minute, Larry. In Britain and Europe the proof laws apply to all firearms, not just shotguns, so the implications of bringing proof laws into the USA would be far reaching indeed. It would have to be at the federal level because the states could never be coerced into all passing similar rules and establishing 50 proof houses. How would it be enforced? If you want to sell a shotgun to a friend will you first have to have it proved? Perhaps some fool has punched the chambers before you got it, now what do you do? I say, the few freedoms we have left should be guarded. We don't need Dudley Dorights telling us how to live our lives. That Government is best which governs least. Sometimes I swear there are still a lot of Tories lurking in the underbrush wanting to bring back kings and queens and other assorted trash.
